Welcome to the First Grade Math with LEGO® Bricks Printable Pack!

This printable math pack contains three activities that are perfect for first grade math. Activity #1: Measuring with LEGO® BricksActivity #2: Brick Number BondsActivity #3: Find the Missing Addend

Tip for Activity #3: Encourage kids to build two LEGO® towers, one to represent each quantity that is known. They can compare the towers to find the missing addend. 5 + what number = 12? Compare towers of 5 and 12 bricks. How many bricks need to be added to the tower with 5 bricks so that it equals 12?

Measuring with LEGO BricksUse 2 x 2 bricks to measure! How many bricks long is each of these objects? Estimate how long each item will be and write down your guess. Then measure the actual length by building a tower of bricks that is equal to the length of the object you are measuring.

Name: ____________________________

Object Estimated Length

Actual Length

Your shoe

An apple or banana

A chapter book

A water bottle

A stuffed animal

Your choice!

Suggestions – measure the height of a chair, a pencil, a pet guinea pig, a doorway, a mailbox, a math book, a backpack, a pillow, a video game controller. What else can you think of?

Brick Number Bonds

Place a number card in the box. Then use bricks to figure out all the ways that you can make an addition sentence equal to that number.

Write your number sentences on the lines.

5 6 7

8 9 10

11 12 13

14 15 16

17 18

Find the Missing Number!

Each addition sentence is missing an addend! Build a tower of bricks to represent the sum. Then build a tower to represent the known addend. Compare your towers to figure out the missing addend and write it in the box.

+7 = 1 1

+ =8 1 4
