  • Styrofoam (at least 1 inch thick)
  • Ping Pong Balls (Tip: If ping pong balls are too difficult for your child to balance, try smaller marbles.)

Depending on the size of your styrofoam and the size of your ping pong balls I recommend evenly spacing the golf tees in columns and rows. Ours are approximately 1.5 inches apart for this activity.

Arrays are visual representations shown in columns and rows. They are a concrete way to show repeated addition and multiplication. Being able to visually see these concepts helps children develop a deeper understanding before they move on to doing these actions mentally.

To describe an array you first name the number of rows in the array, then the number of columns. So in the picture below (if we rotate it just a bit right) we see a 3 by 2 array that shows 2+2+2 (repeated addition) or 3×2 (multiplication).
