make a data table of amounts of toothpaste gather building materials create models of old toothpaste tubes draw a few possible solutions
I gave my students this multiple choice question: A student plans to design a new toothpaste tube that will give the same amount of toothpaste every time it is squeezed. Which should the student do first when designing the new tube?

Only one answer is correct among these 4 choices:
- make a data table of amounts of toothpaste
- gather building materials
- create models of old toothpaste tubes
- draw a few possible solutions

Could you tell me which one is correct?
