Numeracy is to math what literacy is to reading -- understanding the components that make up the mathematical "language." Numeracy involves understanding the different kinds of numbers -- decimals, fractions, percentages, etc. -- and being able to use them to solve problems.
If math was not your favorite subject, don't worry -- encouraging numeracy in your child is surprisingly easy. Here are some quick tips:
1. Drive -- How far have you gone, and how far do you still need to go? How fast are you going and how soon will you get there? And, a scary question, how much will it cost to fill the gas tank?
2. Shop -- Which product is the better deal? How much does each product cost per ounce? If you still use real money, how much will your change be?
3. Cook -- Double or halve a recipe. How do you change the measurements? Read The Math Chef by Joan D'Amico for more ideas.
4. Play Games -- Let your child keep score when you play games or sports. Dominoes and card games are good for recognizing and matching numbers, while Battleship is a great introduction to graphing.
5 Pay Attention -- How do you use math in your life? Share your daily calculations with your child.
