### PRODUCT DESCRIPTION

Shh! No talking!

Silent Sums is a cooperative skill practice activity for middle school students who are learning to find the slope of a line. Each game sheet consists of four problems, with the first three rounds focusing on identifying slope from a graph and the last three rounds finding slope from two points.

Try before you buy! The preview includes full instructions and one round of the activity to try with your class.

This product includes...
1) Cover Page
2) Objectives, standards, and set-up instructions.
3) How to play, variations, and implementation ideas.
4) A blank game sheet template if you would like to add your own equations.
5) Six different game sheets.

How Does It Work?
In groups of four, each student solves a different problem on a shared game sheet. The sum of the four solutions is written in the middle of the game sheet. Students must generate their solutions WITHOUT talking! The teacher only checks the SUM for accuracy.

Why Do I Love It?
1) Interdependence. Every student's work and participation is necessary for the group's success.
2) Cooperative trouble-shooting. If a team's sum is incorrect, what went wrong? They must figure out if the sum was tallied incorrectly, or if one or more of the slopes is incorrect.
3) Helping without enabling. Students can check teammates' work and circle suspected errors, but the constraint of silence means that nobody can do anybody else's thinking for them.
4) Finding the sum of rational slopes adds a review element for computation with fractions.

Thanks for checking out this activity! I can't wait to hear how it goes in your classroom!
