In this problem we need to make the following addition:
2 + 8
According to this I would use the following strategy:
1. Break apart strategy:
This strategy consists in the decomposition or separation of numbers. In this way, we may break number 2 and 8 down to place value and add each, starting with the 8 or keep one number intact and only break second number down by place value and adding each place. Anyway, using this strategy we have:
2 + 8 = ?
Thus, 2 breaks into 1 plus 1 (1 + 1), 8 breaks into 4 plus 4 (4 + 4), so by associative property:
2. Explain how I decided.
The strategy of breaking apart numbers is an easy way to find additions. This strategy is amazing to add larger numbers. Therefore, we may break larger numbers up into hundreds, tens, ones, then add them.
