Task

Valid Equalities?

Illustrative MathematicsVaries

The purpose of this task is to help broaden and deepen students understanding of the equals sign and equality. For some students, an equals sign means 'compute' because they only see equations of the form 2 + 5 = 6. In this task, students must attend to the meaning of the equal sign by determining whether or not the left-hand expression and the right hand expression are equal. This task helps students attend to precision (as in Standard for Mathematical Practice 6). Many of these problems naturally lead to discussions of topics such as place value and properties of addition.
