## Calculator Games for Kids

There are plenty of fun games that kids can use to learn their way around a calculator. By having fun and playing a game, they will not even know they are learning. Here are three fun activities for kids big and small.

The first activity is for young children. Teach them how addition and multiplication are related by having them find out their age in months. For example, if your child is 5, they will put 12 into the calculator five times to see that they are 60 months old.

The next game is called Calc-a-Hundred. Two players can play. They choose a number and then multiply that number to get as close to a hundred as possible. Then the next player does the same with the result from the first player. The first to get to 100 or over wins.

The last game is a brain tickler for even the most mathematical students. In Broken Calculator, students have to find ways to reach a number using only certain keys and functions on their calculator. It forces them to go beyond normal math facts and functions to get the desired result. You can play it online or on a physical calculator.
