Question

Which of the following steps are not followed while using the “make a ten” strategy to add $8$ and $3$ ?

• A. Add two numbers to make $10$
• B. Add the remaining number with $10$ to find the answer
• C. Break down one of the two addends
• D. Use double to add

Answer 1

The correct option is D Use double to add

Say: Let's read the question.

Ask:
$\bullet$ What do we have to do here?
Ans: We need to identify the steps we do not follow while using the “make a ten” strategy to add $8$ and $3$.
$\bullet$ What numbers do we have to add? What equation will be framed?
Ans: $8$ and $3$ are to be added, i.e., $8+3=?$
$\bullet$ What are the steps to add using the 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, $3$ is broken down into $2$ and $1$. Then, $8$ and $2$ are added to make a $10$, and $1$ is remaining.
(iii) Finally, $10$ and $1$, i.e., $10+1,$ are added to get the total of $11.$
$\bullet$ So, based on the given options, what steps are not followed while using the “make a ten” strategy?
Ans: We do not use double to add.

Hence, Option B 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
