Michelle uses the strategy hands up, stand up, pair up in order to provide her students with an opportunity to discuss their math explanations. Michelle's students put their hand up, stand up, and then pair up before starting this discussion.
The students are going to complete the following problem:
In this weekâs ad, Tonyâs Finer foods advertises bananas on sale for 5lbs for $4.45. Jewel has them on sale for $.95/pound. Which store has the better deal?
This problem will reactivate prior knowledge. The students will be required to use a model to support their answer (SMP 4). If students finish early, they can explain their solution in words.
This can also be used as a formative assessment.
