Say, “Now we put it all together. Got your pencil ready? I’m going to make two groups of fish. Write the number for each one. Put a ‘plus’ sign between them, and an ‘equals’ sign after. How many all together? Write it after the ‘equals’ sign. You’re making a math sentence code! Write it and you get the fish.” In this activity, you’re helping your child make a crucial bridge between concrete reality and abstract math symbols for it. It’s almost impossible to practice this too much.
