Subtract with Cubes - Up to 10
๐ฅ Let's break things apart! Use cubes to show how numbers shrink when we subtract.
Do this: Read the concept below, then try the quiz or activity.
Concept
Subtraction means "taking away". We can build a cube tower to show the whole number, and then physically break it apart to subtract!
๐ฏ How to Subtract with Cubes: Example: 8 - 3 = ? 1. Build the Start Number: Build a tower of 8 cubes. This is your total amount. ๐ฆ๐ฆ๐ฆ๐ฆ๐ฆ๐ฆ๐ฆ๐ฆ 2. Take Away: Take 3 cubes off the end of your tower. 3. Count the Leftovers: You now have 5 cubes left in your tower. ๐ฆ๐ฆ๐ฆ๐ฆ๐ฆ 4. Answer: 8 - 3 = 5
Try it
Let's break some towers!
Instructions: Imagine the cube tower. Subtract the cubes to find what's left.
Problem 1: You build a tower of 9 cubes. A monster knocks off 4 cubes. How many are left? * Imagine the tower: 9 blocks * Take away: 4 blocks * Remaining: ___
Problem 2: Start with 6 cubes. Take away 6 cubes. * 6 - 6 = ___
Problem 3: Start with 10 cubes. Take away 2 cubes. * 10 - 2 = ___
