Question

Does it use the make-ten strategy? "I took 2 cubes from the 5 and put them with the 8, and then I knew 10 and 3 is 13."

A. Yes
B. No

Answer 1

Yes, the student's approach of reorganizing numbers to make a ten before adding the remaining amount exemplifies the make-ten strategy in mathematics.

Step-by-step explanation:

The strategy mentioned by the student does indeed use the make-ten strategy. The make-ten strategy involves reorganizing numbers to make a ten, which simplifies addition. In the given scenario, the student takes 2 cubes from the 5 and adds them to the 8, thus forming a group of 10 (from the 8 and 2) and a leftover group of 3 (from the original 5). The student then easily adds 10 and 3 to get 13. This is a classic use of this strategy, which is highly effective for mental math.
