Add with Cubes - Sums up to 10

๐Ÿงฑ Let's be builders! We can use cubes or blocks to build number towers. When we add, we connect two towers together to see how tall they become!

Do this: Read the concept below, then try the quiz or activity.

Lesson 5 of 180

Concept

Using cubes or building blocks makes addition feel like playing! Each block is a "unit," and stacking them helps you count and add.

๐ŸŽฏ How to Add with Cubes: 1. Build Tower 1: Count out blocks for your first number and build a tower. 2. Build Tower 2: Count out blocks for your second number and build another tower. 3. Combine Them!: Connect the two towers together to make one big tower. 4. Count the Total: Count all the blocks in your new, big tower. That's your answer!

Example: 4 + 3 = ?
*   Tower 1: Build a tower with 4 blocks.
*   Tower 2: Build a tower with 3 blocks.
*   Combine: Snap them together.
*   Count: Your new tower has 7 blocks. So, 4 + 3 = 7.

๐Ÿ’ก No cubes? No problem! You can draw them instead. Draw 4 squares stacked up, and 3 squares next to it. Then count all the squares.

Try it

Let's build some math problems!

Instructions: Use building blocks, cubes, or draw squares to solve these problems.

Problem 1:
Build a tower of 5 and a tower of 2. Connect them. How many blocks in all?
*   5 + 2 = ___
Problem 2:
Build a tower of 3 and another tower of 3. What is the total height?
*   3 + 3 = ___
Problem 3:
Create a stack of 6 blocks. Create another stack of 4 blocks. Combine them. What have you made?
*   6 + 4 = ___
Problem 4:
Draw a tower of 1 block and a tower of 7 blocks. How many blocks did you draw?
*   1 + 7 = ___
๐Ÿ† Tower Challenge:
Can you find three different ways to build a tower that is 8 blocks tall by combining two smaller towers?
*   ___ + ___ = 8
*   ___ + ___ = 8
*   ___ + ___ = 8
