A Rapid Rounding Game

A Rapid Rounding Game Activity

based on 7 ratings

As third graders begin to work on more complex  computations, they will need some way to quickly double check their answers. That's why rounding is such an important skill set to master in third grade. The good part? "Rapid Fire Rounding" can be fun. This kinesthetic game will help your child practice this skill and get her adrenaline rushing.

What You Need:

  • 9 pieces of poster board in various colors
  • masking tape
  • large black marker
  • index cards
  • stop watch

What You Do:

  • Label the poster boards by hundreds from 100 to 900 (100, 200, 300, 400, 500, 600, 700, 800, 900). Each poster board should have one number on it. Tape these all in a row to the ground outside, or in an open space in your home where it's okay to stomp on them.
  • On the index cards, write a variety of numbers from 100 to 900, such as 136, 879, 510, etc... There should be about 40 cards.
  • Tell your child that you are going to hand him a card, and he has to round the number to the nearest hundreds place and then jump on the correct answer as quickly as he can. After three tries to get the slickest time, switch places. Now it's your turn to claim the title as the fastest rounder!
  • After a few rounds like this, shuffle the poster boards around so that they are no longer in order, but all mixed up. How does this affect your time?

This game is especially helpful to kids who struggle with pen and pencil sitting tasks.  In this activity, there's nothing like "voting with your feet" when it comes to understanding how this math concept works.
