The correct option is
D 14Say: Let's read the question.
Ask:
∙ What do we have to do here?
Ans: We have to add
8 and
6 using “make a ten”.
∙ What are the steps to add using a make a ten strategy?
Ans: (i) We need to identify the number that needs to be added to the bigger addend to make it into a ten. Here,
2 needs to be added to
8 to make it into a ten.
(ii) We break down the smaller number. Here,
6 is broken down into
2 and
4. Then,
8 and
2 are added to make a
10, and
4 is remaining.
(iii) Finally,
10 and
4, i.e.,
10+4, are added to get the total of
14.
∙ So, what is the completed equation?
Ans:
8+6=14
Hence, Option C is correct.
WB: Use the whiteboard to write the equation and find the total using the make a ten strategy as shown and explain the steps
Probing Question:
Can we solve the same equation using the “make a ten” strategy by breaking down
8 ? If yes, what numbers would 8 be broken down into?
A. Yes,
8 can be broken down into
4 and
4. Then, 4 and
6 can be added to make a
10. Finally,
4 and
10 can be added to get a total of
14.
