Missing Operator Worksheet/Game
Welcome to Missing Operator game. This is a game about finding the missing relationship between numbers. Instead of giving the answer, you are finding the action (the operator) that makes the equation true. Scroll down the page for a more detailed explanation.

 

 

How to Play

1. Analyze the Equation:
   Look at the numbers on the screen. There will be a pink dashed box where a math sign should be.
   

2. Determine the Relationship:
   Addition (+): Choose this if the two numbers on the side of the operator combine to make a larger sum.
   Subtraction (-): Choose this if the first number is being reduced to a smaller difference.
   

3. Check for the “Flip”:
   The game will occasionally swap the sides. Whether it’s 5 [?] 2 = 7 or 7 = 5 [?] 2, the logic remains the same.
   

4. Select Your Sign:
   Click the large + or - button.
   Green: You got it right! Your score increases.
   Red: That wasn’t the right sign. The game will highlight the correct sign in green so you can see why it works.
   

5. Advance:
   Click the Next Level ➜ button to generate a brand new math sentence.
   

Why It’s Helpful for Learners
This game helps build operation sense. Instead of just calculating, students learn to predict outcomes. For example, if they see 8 and 3 resulting in 5, their brain begins to automatically recognize that as a “subtraction” relationship.
