Our Equal Sign lesson plan not only defines an equal (=) sign for students but also offers a history of the equals sign and how it came to be the agreed-upon symbol in math. Students are reminded that the equals (=) sign is always placed between two (or more) expressions that have the same value. Unlike other math symbols like the plus (+) sign or minus (-) sign, the equal (=) sign does not tell you to do anything, it just gives you information. Students are asked to complete a fun, interactive game in which they are each given a number and told to find their classmate with an equal number as quickly as possible. Students are also asked to identify equations in which both sides equal each other.

At the end of the lesson, students will be able to understand the meaning of the equal sign and apply the concept of equality to determine if an addition or subtraction equation is true or false.
