Teacher Notes
Even though the gap is "times by 0" we are going to do a wider concept of matching a problem to an equation. We will work towards "times by 0" and "times by 1"
TO BEGIN WITH AVOID TELLING THEM: TIMES BY 1 is the same, TIMES by 0 is 0. We want them to make sense of the problems. If some bright spark brings it up use prompts like - how do we know that is true? Even if someone know the rules, making the connections (below) will still be beneficial.

- Provide paper to class for drawing.
- Class should discuss who is right in small groups.
- They should a picture of the problem.
- Lead a conversation linking the problem, the equation and the drawing.
- "Times" can be introduced as "groups of"
