Grams and kilograms - measurement lesson (video) for 3rd grade
I weigh things on a kitchen scale while helping children learn about the two most important units in the metric system for measuring weight: GRAMS and KILOGRAMS.
I weigh an onion, tomatoes, dominoes, Mathy my mammoth mascot... and his cousin Giganto the mammoth also.
This is a neat activity to do at home or in the classroom - it helps children learn about units of weight! Besides weighing various items, find food items that have their weight (in grams) labeled, and check if they really weigh that. :) Don't forget that the packaging (such as a bottle) also weighs something. hing.
