Order of Operations

Subject Area





This digital tool explains the order of operations when solving a number sentence with more than one operation. This tool has a song to help students remember the order of operations. This digital tool takes the students step by step in solving a number sentence with more than one operations.  


    Determine and justify solutions for two-step word problems using the four operations and write an equation with a letter standing for the unknown quantity. Determine reasonableness of answers using number sense, context, mental computation, and estimation strategies including rounding.
