### Description

For many of my kiddos, understanding how dilation affects perimeter, area, and volume is one of the most challenging concepts in our 8th grade curriculum. Some students pick it up right away; others need bountiful practice opportunities. I originally created this tic-tac-toe game as a differentiated review activity to address the needs of both struggling and high-achieving students. (All three game boards are shown, in their entirety, in the product preview.)

The first game board is for those who are working to grasp the concept of dimensional change at the foundational level. In this version, perimeter, area, and volume are given; students need only to apply the scale factor accordingly. Computation is straight-forward so that kids can focus on understanding the standard.

The second game board is for students who have a basic grasp of how proportional dimensional change affects perimeter, area, and volume measures, but could benefit from further practice. In this game, students must use some formulas and apply scale factor appropriately. The computation is a bit more challenging than that found in the first game.

The third game board is meant to challenge high-performing kids to think deeply and flexibly about perimeter, area, and volume formulas in addition to applying scale factor. The computation is more challenging than that required in the second game, and knowledge of Pythagorean Theorem is needed to find some missing measures.

I have since come back to this game many times to use for small group interventions and as preparation for our state-mandated assessment (STAAR). I have used it as a multi-leveled worksheet (the game boards print nicely in black and white), partner game, and station activity. Ideas for implementation are included in the resource along with a student answer sheet (for those who opt to laminate the game boards) and a complete key.
