Question

Sophie says, "To find 8 X 8, I can find 8 X (4 + 4)."Do you agree? Explain.3rd grade subject

Answer 1

Step 1

Given:

$8\times8$

Required:

$\begin{gathered} To\text{ agre}e\text{ that if I can find 8}\times(4+4)_{} \\ \text{then I can find 8}\times8 \end{gathered}$

Step 2

Find out if you agree or disagree

$\begin{gathered} 8\times(4+4) \\ =\text{ (8}\times4)+(8\times4) \\ =\text{ 32 + 32 = 64} \\ or \\ 8\times(4+4) \\ \text{But (4+4) = 8} \\ \end{gathered}$$\begin{gathered} \text{Therefore,} \\ 8\times(4+4)\text{ = 8}\times8 \\ \text{Therefore, To find 8}\times8,\text{ I can find 8 }\times(4+4) \end{gathered}$

Hence, I agree.
