Brainstorm for Summing Up

Here’s our group brainstorm of what students could get out of this activity. We can’t do it all, but I thought the list might help you:

• scaling (seeing it visually and within the formula)
• What happens when you…? (looking for structure in expressions)
• testing if something is true or false – students being scientists
• having strategies for testing validity of statements: (1) using the same number for the same values – like Daphne using 3 for the radius in the different shapes, (2) just trying numbers, (3) using what you come up with – like if you double something in a formula, use what you learn when considering what happens when…
• connections between the different formula
• engaging experience using the formulas on the TASC reference sheet
• the understanding that volume is not shape dependent (the way students sometimes define area as LxW)
• creating function tables from one of the statements

Brainstorm for Student Challenges to Address/Draw Out in Problem-Posing and Launch

Here are some of the obstacles we identified that students might have for the T/F statement activity:

• vocabulary
• exponents
• pi
• fractions (4/3)
• order of operations (in surface area formula)
