We can break apart a figure to find the area, by breaking it into two or more rectangles. We find the area of those smaller rectangles, then add their areas together to get a total area of the original figure. We can use the Distributive Property to break apart an array. It may be easier for us to break apart a figure into sizes that will be easier to multiply their length times their width. We can break apart a figure into any size rectangles. We solve two word problems involving the area of combined rectangles.

We can solve area problems by using the strategy "find a pattern". We make a table to list the lengths and widths of rectangles and find their areas. Then we can examine the table and look for patterns in the lengths, widths, and areas. To solve word problems, we need to read and understand the problem, identify or circle important information, choose a strategy to solve the problem, and check our work for mistakes. We can find the area of rectangles by multiplying its length times its width. We can also find a side measure by using division if we know the area of the rectangle and the other side measure. We see how areas are related by using a table of information. We find patterns in the table. When the lengths are the same and the widths are doubled, the areas will be doubled. When the lengths are the same and the widths are halved, the area will be halved. When we double both the length and the width, the area is 4 times greater than the original area. When we triple the width, the area triples. If we double a rectangle's length, but cut its width in half, both rectangles will have the same area.

See the description for links to videos 11.4 and 11.5. We have learned that we can count the unit squares to find the area of a rectangle. We can also multiply to find the area of a rectangle. A rectangle that is covered by unit squares is like an array. It has rows of unit squares with an equal number of unit squares in each row. We can also use repeated addition to find the area of a rectangle. When a figure is broken into unit squares, we can find its area using three methods: we can count the squares, use repeated addition, or multiply the number of rows by how many are in each row. When the figure is not broken into unit squares, we can measure two sides with a ruler and use multiplication. If we know more than one way to find a figures area, we can use one method to find the area and another method to check our answer. We show an example of two rectangles that have the same area, though they have a different numbers of rows. Just like we learned with arrays, we can use the Commutative Property of Multiplication which states that we can multiply in any order. We show an example of finding how much more area is green than pink in a figure. We select each equation that can be used to find the area of a given rectangle. We look ahead towards 4th grade math and higher when we will learn how to find the area of a figure by using multiplication and subtraction, or multiplication and addition.

As we learned in video 11.4, area is the number of unit squares needed to cover a flat surface. We can find the area of a plane figure by estimating how many square units are needed to cover the figure, using unit tiles making sure there are no gaps or overlaps, or counting the number of square units covering the figure. We model using inch squares to cover the surface of a rectangle. We estimate the number of large squares needed to cover a rectangle compared to the number of small squares needed to cover the same rectangle. It's very important to use a label with an area measurement because the label lets us know what size unit was used to measure the area. We find the difference of an area of gold squares to the area of white squares in a given figure. We find how many square units are needed to be added to a figure so it makes a perfect square.

See the JoAnn's School Facebook images for dot paper that you can copy, paste, and print for your use. A unit square is a square shape with a side length of one unit. The unit might be inches, feet, yards, miles, or in metric as centimeters, meters, kilometers. It has the area of 1 square unit. Area is the measure of the number of unit squares needed to cover the inside of a flat surface. We use dot paper to draw figures made from unit squares. We draw different figures that are made from the same amount of unit squares and we see they have the same area as each other, but their shapes look different. We compare a shape's perimeter to its area. We find the perimeter and area of several figures.

We can find the unknown length of a side in a plane shape when we know its perimeter. We add the given side lengths and subtract there sum from the given perimeter. The perimeter of a figure is the distance around all the sides of the figure. When we add the given side lengths, we can use a variable to take the place of the unknown length. We find unknown side lengths for a rectangle, square, regular hexagon, and irregular shaped polygons.

We learned in our last lesson that perimeter is the distance around a shape. We can find the perimeter of a shape by adding the lengths of its sides to find the sum. We can measure perimeter by estimating and using benchmarks, by using a ruler to measure the length of the sides, then add the lengths to get a sum. Then we can compare the sum to our estimate. Using a ruler, we can measure each side with inches, or with centimeters. If the figure has sides of equal length, we can multiply the measure of one side by the number of sides. We need to be careful when finding the perimeter of a shape that seems to have equal side lengths. If we're not told the sides are of equal length, we cannot assume that they are equal. We need to measure them! We show several examples of measuring sides of figures with a ruler to find the perimeter in inches or centimeters. We solve two word problems involving perimeter.

Perimeter is the distance around a shape. We can find the perimeter of a shape by adding the lengths of its sides to find the sum. If all the sides of a shape are equal in length, we can multiply the length of each side by the number of sides. On dot paper, the distance between two dots is one unit. We can count the amount of units to find a figure's perimeter. A rectangle has two pairs of sides of equal length. If we know the length of one side, or two sides, we can find the perimeter of the rectangle. We can use grid paper to find the perimeter of figures by counting the number of units around the sides. We choose a starting point and count around the sides of the shape until we have counted all the units. We find the perimeter of a triangle with sides of equal length that has a perimeter of 15 inches. We find the lengths of the sides of a hexagon, with sides of equal length, that shows one side is 4 centimeters.

We can use models to solve liquid volume and mass word problems. We can draw a bar model to show the information, write an equation, then solve the equation. We can draw a picture to help us understand the problem. We can use a pan balance and gram masses. We place an object in one pan and gram units in the other pan until the beam of the pan balance is level. We do several examples of word problems that involve liters or mass. We discuss how to choose the correct operation sign by looking for clue words. We also talk about word problems that may have unnecessary information.

My metric chart for mass purposely does not have decimals because this is a 3rd Grade level lesson. Mass is the amount of matter in an object. The gram is the basic metric unit for measuring mass, or the amount of matter in an object. An object with a mass of 1 kilogram has more matter than an object with a mass of 1 gram. A pan balance (or balance scale) has a plate or bowl on each side, each pan is the same distance from the center (fulcrum). We can use a pan balance to measure mass. The object with more mass will make its pan go lower than the other side. We decide if an object should be measured in grams or kilograms. We match the object to the unit we would use to measure its mass. When two objects have the same mass, the pans will be even. We discuss how you can make a homemade pan balance using a coat hanger, string, and two paper cups. Mass is different than weight. The mass of an object IS NOT affected by gravity, so the mass of an object is the same on every planet. Weight IS affected by gravity, so it will change from planet to planet because each planet's force of gravity is different. A student that weighs about 36 Kg on Earth would weigh about 6 Kg on the Moon. Their mass didn't change, but their weight did. Mass is not size or weight. It's the amount of matter in the object.

Liquid volume can be measured using U.S. Standard measures, or metric measures. In metric measures, 1 liter is about 4 cups in U.S. Standard measure. Liquid volume is the amount of liquid in a container. The liter, abbreviated with L, is the basic metric unit for measuring liquid volume. When we pour liquid into a container, it takes the shape of the container. A benchmark is a known size or amount that helps us understand a different size or amount. An estimate is an answer that is close to the exact amount. We compare different size containers to see if they are less than 1 liter, about 1 liter, or more than 1 liter. We compare different containers to see if they are less than 1/2 liter, about 1/2 liter, or more than 1/2 liter. We discuss which countries use the metric system and which countries do not. We pour liquid from one container to another container to compare how much liquid volume the containers hold.

The left side of a ruler represents 0 inches. The numbers 1, 2, 3, and so on represent whole inches. A ruler is like a number line because they both start at 0 and are marked in equal sized distances. The marks on a ruler show the whole inches, and the fractional parts of each inch. Each 1/2 inch mark is centered between each whole inch. The fourth inch marks are centered between each 1/2 inch. We discuss examples of measuring length to the nearest inch, or to the nearest half inch. We can measure to the nearest half inch when our measuring tool only has inch marks on it. We can measure to the nearest fourth inch when our measuring tool only has inch and half inch marks on it. We use a line plot to show measurement data. We measure and record the measures on a line plot. When we measure to the nearest half inch, or the nearest fourth inch, the length of our object may be a whole number answer.

We can solve word problems involving elapsed time by using the strategy Draw a Diagram. We can draw a number line to find the answer to an elapsed time problem. We can also use an analog clock face to help us, but we're focusing on number lines for this lesson (see previous videos 10.3 and 10.4 for these strategies). To find an ending time, we need the starting time and elapsed time. We count on forward from the start time. To find a starting time, we need the ending time and elapsed time. We count back from the ending time. To help us solve word problems, we can circle or underline the question, circle or underline the important facts, and choose a strategy we know. We solve several word problems involving elapsed time and check our answers.

We can find an ending time if we know the starting time and the elapsed time. We can find a starting time if we know the elapsed time and the ending time. We can use a number line or analog clock to help us. We can skip count elapsed time on a number line or analog clock by 5 minutes, 10 minutes, 15 minutes as quarter hours, 30 minutes as half hours, then count on by ones. We can break apart elapsed time to make less jumps on a number line. We discuss several examples of using a number line or analog clock to find elapsed time. We finish with a two-step word problem for elapsed time.

A time interval is the amount of time between events. It's the amount of time that went by from the start to finish of an event. Elapsed time is a time interval. We discuss how to measure elapsed time in minutes. We find the starting time. We use a number line, analog clock, or subtraction to count the minutes to the ending time. Finding elapsed time by using an analog clock or by using a number line are alike because we begin at the start time and count on for both. We can use one method to find the elapsed time and check our answer with the other method. We see the importance of writing a.m. or p.m. when we write time.

See the link below to my Clocks, Time, and Calendars playlist. A.M. is the abbreviation for the Latin ante meridiem. It represents the hours and minutes from 12 o'clock at night to 11:59 in the morning. P.M. is the abbreviation for the Latin post meridiem. It represents the hours and minutes from 12 o'clock at lunch time to 11:59 at night. There are 24 hours in each day. This means the hour hand will go around 2 full times for each day. The first 12 hours are a.m. The second 12 hours are p.m. We see the different acceptable ways to write AM and PM. We look at the numbers on the clock stretched out as a number line showing morning as a.m. and afternoon and evening as p.m. We put some activities under the correct heading of a.m. or p.m. we use clues from a statement to determine whether a clock is showing a.m. or p.m. We write the correct time using a.m. or p.m.

See the link below for the playlist about telling time. We first learned about telling time in Grade 1 and Grade 2 math. We learned that there are analog and digital clocks. We also learned that each number on an analog clock represents 5 minutes for the minute hand and 1 hour for the hour hand. We previously learned that an analog clock can be divided into two parts, after the hour and before the next hour. We also learned that the clock can be divided into quarter hours of 15 minutes each. We can tell time to the exact minute by skip-counting each number by fives, then counting on one minute at a time. We review the meaning of clockwise and counterclockwise. We talk about how we can write time as minutes before an hour, after the hour, or as the exact time. We discuss quarter past and quarter to the hour, and half past the hour.

Equivalent fractions name the same amount. We can use models to name equivalent fractions. We use fraction strips, fraction circles, fraction walls, and drawings with shaded parts. We discuss how a pizza cut into eighths can be shared among four people, and the two different ways a fraction can be written to represent how much each person ate. We see how to write a fraction for a shaded part of a model. We identify fractions that are equivalent to 1/2 or equivalent to 1/3.

When two or more fractions name the same amount, they are equivalent fractions. Equivalent means equal to, or having the same value. We can use models to find equivalent fractions by carefully folding a sheet of paper into same size parts. We can also model equivalent fractions by using a number line, fraction strips, or fraction wall. We look at a list of fractions that are equivalent to a unit fraction. We see the patterns that are made by their denominators as multiples of the denominator of the unit fraction. When the numerator and denominator are the same number, the fraction is equivalent to 1 whole. You can go to the JoAnn's School Facebook page image section for fractions strips and fraction walls to copy, paste, print, and cut out to use as models. See the link below.

On Wednesday July 17, Lola didn't eat her dinner at all and was acting extremely lethargic. On Thursday July 18, she didn't eat breakfast or dinner. On Friday July 19 when she didn't eat her breakfast, I took her to our vet. He found she had a fever and a high white blood cell count, which indicates an infection. He took an x-ray of her chest and abdomen and didn't see anything significant. She's now getting a lot of rest, and taking an antibiotic. Saturday morning I was able to get her to eat a tablespoon of scrambled egg. That isn't enough. I then tried making her a couple tablespoons of fresh salmon with rice for dinner, which she usually loves, and she ate it. Sunday July 21, she ate about 1/3 of a normal sized meal for breakfast, then ate about 1/2 a normal meal for dinner. Her appetite is returning. We still have several more days for her to take the antibiotic. We have no idea what caused her illness! Please consider supporting my work by becoming a patron on Patreon, or by using PayPal.

You'll be less confused if you watch lessons 9.2, 9.3, and 9.4 before you watch this one. See links below. We can compare and order fractions by comparing their numerators, or comparing their denominators. We can also use fraction strips or fraction circles to compare the size or amount of the unit fractions. We can order them from least to greatest, or greatest to least. We cannot compare fractions that represent items of different sizes. We need to compare fractions that represent the same-size whole. When we order fractions with the same numerator from least to greatest, the denominators go from greatest to least. When we order fractions with the same denominator, the numerators go down as the number of pieces go down. We can line fraction strips next to each other to compare the longest set of fraction strips to the shortest set. We can use a fraction wall to help us compare fractions. See the Joann's School Facebook page image section for a fraction wall that you can copy, paste, and print for your own use linked below.

It's important that you watch lesson 9.2 and 9.3 before you watch this lesson. There are links below. To compare fractions, we can use the strategies: use missing pieces from the whole, the same numerator, the same denominator. To use the missing pieces strategy, we compare pieces missing from a whole. We can use the missing pieces strategy when the numerators OR denominators are not the same. We can use these strategies to compare fractions greater than one, also called improper fractions. Fractions greater than 1 have a numerator that is larger than its denominator.

We can compare fractions that have the same numerator by looking at their denominators and comparing the size of their pieces. The fraction with the greater denominator has smaller pieces, the whole is divided into more pieces that are smaller. The fraction with the smaller denominator has larger pieces, the whole is divided into less pieces. We use fraction strips to compare fractions that have the same numerator. We see how 1/6 can be greater than 1/4 because the whole objects that they represent are different sizes. We use a less than, greater than, or equal to sign to compare fractions that have the same numerator.

We can compare fractions that have denominators that are alike. We can use fraction strips to model each fraction, then show their location on a number line. We can also use numerators to compare fractions that have the same denominator. We discuss and show several examples of these methods.

Education for everyone!
I have over 2,600 Math videos on YouTube, ranging from 1st grade through Algebra 2 and high school Geometry. Many don't auto-upload from YouTube, I'm sorry! It would be impossible for me to upload all of them onto BitChute.
I've included most of my GED Math videos and the Grade 1.
I'm planning to do Trigonometry, then a Pre-Calculus Playlist in the future.
You can study an entire grade level of Math, lesson by lesson with my playlists, in order. You can find the textbooks online.
Catch up to your class, work ahead, pass the GED, or place higher on college entry tests to avoid remedial classes.
