This What is Equal? lesson plan also includes:
Help your mathematicians understand that an equal sign doesn't just mean the solution to a math problem. It also indicates that the values on either side are equal to each other. Using beans, scholars visualize this concept as you review several simple addition and subtraction problems. They place the correct number of beans on either side of a scale on their workmats for each side, then observe that the number of beans is the same! A "Three in a Row" game synthesizes this skill in a fun way.
