Domino Effect is a collaborative game where groups of 3 - 4 students work together to find the solution to the current problem — which reveals the next problem. Students solve 16 problems per game. If the solution to the last problem matches the answer on the starting card, the team has correctly completed the activity!

This includes 2 difficulty levels of the game, with 32 problems in total.

What math skills does it practice?

The activity includes two difficulty levels of the following:

  • Level 1: Finding percent of a number. Example: What's 15% of 85

  • Level 2: Finding the whole, given the part and the percent. Example: 70% of ____ is 23

This activity includes two difficulty levels so that you can differentiate students, or play twice back-to-back to practice.
