Order in Addition

The video tutorial introduces a scenario with a train where Sam and Sela count children in different compartments, demonstrating addition. It explores how changing the order of numbers in addition sentences does not affect the sum. The tutorial further illustrates this concept using cubes and a number card, reinforcing the idea that numbers can be added in any order to achieve the same result.

What cubes did Sela pick to make the number 6?

What is the sum of the cubes Sam picked?

What observation can you make about the addition sentences involving the numbers 1, 2, and 3?
