Activity 1
All the Way to the Top
Priya, Kiran, and Lin use large playing bricks to make towers. Here are the heights of their towers.
Priya: inches
Kiran: inches
Lin : inches
Show your reasoning for each question.
How much taller is Lin’s tower compared to:
Priya’s tower?
Kiran’s tower?
They are playing in a room that is 109 inches tall. Priya says that if they combine their towers to make a super tall tower, it would be too tall for the room. She says they must remove 1 brick.
Do you agree with Priya? Explain your reasoning.
Activity 2
Stacks of Blocks
Andre is building a tower out of foam blocks. The blocks come in three different thicknesses: foot, foot, and foot.
Andre stacks 1 block of each size. Is the stack more than 1 foot tall? Explain or show how you know.
Can Andre use only the -foot and -foot blocks to make a stack that is feet tall? If you think so, show one or more ways. If not, explain why not.
