# Investigations

The problems you find below can be closed, meaning there is one answer, or open-ended, meaning there are several possible responses.

• You need to use mathematical reasoning (and explain through mathematical language) to find the possible responses.
• All work needs to be organized, neat and considerate of your audience
• You will work with classmates on Friday to discuss the answer and present all possible solutions (and demonstrate your understandings)
• Working with parents and guardians at home is fine
