Instructions:

1. Complete question #1, then watch the videos below to see how we can go about testing and proving a conjecture.

2. As you continue your work on the math activity, watch the video to hear Marta explain the three components of a representation based argument.

3. Work through all the questions and prompts and then select from the videos below to hear how the teachers thought about the work. Consider how your conclusions about multiplying even or odd
   numbers was similar or different.

4. Select from the synthesis videos below. Consider how you were taught about odd and even numbers, how was this math activity different?
