Unit 2, Lesson 6

Build and decompose a kilogram learning about the size and weight of kilograms and grams

EngageNY 60 min(s)

This lesson introduces students to metric weight measured in kilograms and grams. Students learn to use digital scales as they explore these weights. They begin by holding a kilogram weight to get a sense of its weight. Then, groups of students work with scales to add rice to clear plastic zippered bags until the bags reach a weight of 1 kilogram. Once the bags reach that weight, students decompose a kilogram using ten-frames. Students then relate the decomposition of a kilogram to place value and the base ten system.
