Explain your reasoning
The idea
Explaining a solution makes hidden steps visible. State the goal, describe your method, and connect each step to a reason. A partner can ask questions rather than only announce whether the answer is right. Discussion is most useful when everyone can participate.
Worked example
For 18 ÷ 3, explain that 18 objects divided into three equal groups gives six in each group. The explanation shows why the operation fits the problem.
Another application
After solving 24 ÷ 4 = 6, use multiplication to check: four groups of six make 24. This explains the grouping interpretation and offers a way to verify the answer.
A common misunderstanding
A confident explanation can still contain a mistake. Partners should ask how steps connect to the problem and check the result.
Try it yourself
Work with a partner: one explains a solved example, the other identifies a clear step and asks about an unclear one. Switch roles.
Check your understanding
Is an answer alone a complete explanation?
Reveal the explained answer
Usually not. The method and reasoning also matter.
