We learned about metric mass and liquid volume in 3rd grade, the links are below. We learned about grams, kilograms, and liters. We also learned about Mass versus weight. In this lesson, we're going to focus on kilograms and grams for Mass. We're also going to focus on liters and introduce milliliters. The gram is the basic unit for metric Mass. We learned in video 12.6, an exponent tells us how many factors we need to multiply to each other. We convert kilograms to grams using multiplication. Because we need 1000 grams to have 1 kilogram, 1 gram is one of 1,000 equal parts of a kilogram. We write a gram as a fraction and as a decimal of a kilogram. The liter is the basic unit for metric liquid volume. We compare liters and milliliters by using multiplication to convert liters to milliliters. Because we need 1000 ml to have one L, one ml is 1 of 1,000 equal parts of a liter. We write 1 milliliter as a fraction and as a decimal of a liter. We compare using the symbols for less than, greater than, or equal to, for kilograms and grams, and liters and milliliters. We need to make sure to compare like units. This means we may need to convert the larger units to smaller units first. We solve a few word problems that involve converting liters to milliliters, and kilograms to grams.
