This is an activity designed as practice for Evaluating Expressions in Algebra 1. There are three levels of difficulty so that students can practice at a level that suits their current abilities or they can complete multiple levels of difficulty for extra practice and enrichment. Each domino has an expression on the right side (ex. "f(3)") and a value (ex. "7") on the left side. Students must take the expression on the right, evaluate the expression for the given value, then once they have the r
