Skills Covered

How to Use This Pack

Five pages about weight on a two-pan balance scale. On pages 1 and 2 each scale tips toward the heavier side: students circle the heavier thing, then the lighter one. Page 3 adds level scales, and students circle heavier, lighter, or same for the small picture. On page 4 every scale is level, so students count the blocks on one side to find what the thing on the other side weighs. Page 5, for 1st grade, has six sentences such as "The turtle weighs more than 5 blocks." to check against the scale.

In the Classroom

Start with a real balance or a ruler laid over a pencil: put a book on one side and a crayon on the other and ask which side went down. Then hold two things, one in each hand, and let students guess before the scale shows them. A balloon and a small rock make a good surprise: the big one is not the heavy one.

At Home

Hold two things from the kitchen, one in each hand, and ask which one is heavier. Then make a hanger balance with two bags and check the guess. Read the sentences on page 5 aloud together.

Tips for Success

The heavier side goes down; the lighter side goes up
A level scale means both sides weigh the same
Bigger is not always heavier: look at the scale, not the size
Count the blocks one at a time and touch each one
On page 5, count the blocks first, then read the sentence
