Time for a new math puzzle! This week, we have a true or false equation grid: each square contains an equation, and the job of the puzzle-solver is to spot the wrong equations and then to color them in. If done correctly, the wrong equations form a pattern! For my classes, this pattern is often a letter or a number, although that’s not the case in the puzzle below.
These grids are an excellent way to make sure that a student has a robust, relational view of the equals sign. They are also a good spot check for whether they understand the difference between expressions like 2﹣3 and 3﹣2.
