Product Description
First Week Activities are significant in building relationships and a positive learning environment.

Getting to know your students is an essential first step in building relationships.

Five Fives Activity allows you to observe students’ number sense and facility with number operations.

The goal is for students to use exactly five fives to produce the numbers 1 to 25. Students can use any math operation, including addition, subtraction, multiplication, division, as well as square root, exponentiation, and factorials. They can concatenate numbers (5, 55, 555), use a decimal point, and also use a repeating decimal bar.

This activity is flexible. Students might work in teams to produce solutions cooperatively and post them on the board. They might work as partners to fill out a team worksheet. Students could write solutions on sentence strip paper to post on a bulletin board or enter them on a shared spreadsheet (Google Sheets, for example).

As you debrief with students, ask what strategies they used? Did they find any shortcuts? What made some numbers easy? What made some numbers difficult?

As multiple solutions are found for the same number, students might discuss the elegance (simplicity) value of each solution.

A set of possible solutions is included.

Hope your first week of school is amazing!
