Decide if each statement is true or false. Be prepared to explain your reasoning.

Andre wants to know how much rope is needed to enclose the new rectangular school garden. The length of the garden is 30 feet. The width of the garden is 8 feet.

• Clare says she can use multiplication to find the length of rope Andre needs.
• Diego says he can use addition to find the length of rope Andre needs.

Who do you agree with? Explain or show your reasoning.

Your teacher will give you either a Problem Card or a Data Card. Do not show or read your card to your partner.

Information Gap routine. Step 1, both students read the problem card. Cycle. Problem card student says, can you tell me, fill in the blank? Data card student says, why do you need to know, fill in the blank? Problem card student says, I need to know, fill in the blank, because dot, dot, dot. Data card student listens to partner's reason and answers with information from the data cards. Repeat cycle until the problem card student can state, I have enough information to solve this problem. Both solve the problem independently and continue to ask questions if more information is needed. Finally, share data card, then compare strategies and solutions. 

Pause here so your teacher can review your work.

Ask your teacher for a new set of cards and repeat the activity, trading roles with your partner.
