Commutative Property in Addition

The video tutorial explains a math problem involving the addition of 3, 8, and 2. Two students, Aiden and Christopher, solve the problem using different methods. Aiden adds 3 and 8 first, then adds 2, while Christopher adds 8 and 2 first, then adds 3. Both methods yield the same result, demonstrating that the order of addition does not affect the outcome. The tutorial uses counters to visually represent the problem, emphasizing that all numbers are part of the same group. The key takeaway is that different approaches to addition can be equally valid.

How did Aiden solve the addition problem?

• He added 3 and 8 first, then added 2.

• He added 8 and 2 first, then added 3.

• He added all numbers at once.

• He added 3 and 2 first, then added 8.

What was Christopher's first step in solving the problem?

• He added 3 and 2 first.

• He added 8 and 2 first.

• He added all numbers at once.

• He added 3 and 8 first.

What tool was used to visually demonstrate the problem?

• A ruler

• A number line

• Counters

• A calculator

What mathematical property allows both Aiden and Christopher's methods to be correct?

• Identity property

• Associative property

• Distributive property

• Commutative property

Why does the order of addition not matter in this problem?

• Because they are all even numbers

• Because they are all odd numbers

• Because the numbers are small

• Because of the commutative property
