# Personal Expressions

Encourage your child to write algebraic expressions to represent everyday situations, using words and letters—no equal signs, please!

## What You Need:

- Paper and pencil

## What You and Your Child Will Do:

- Your child has learned that a variable is a letter, such as
**n**or**r**, that stands for a number. Your child has also learned that a mathematical expression that uses a variable is called an algebraic expression. - So, an algebraic expression for:
- a number (
**n**) added to 12 is**n**+ 12 - 10 less than the number of tools in a toolbox (
**n**) is n – 10 - the sum of 9 and 7 divided by a number is (9 + 7) ÷
**n**

- a number (
- Challenge your child to write algebraic expressions for these phrases:
- some number (
**n**) plus your child's age - 1 less than the number of meals your child ate yesterday (
**n**) - 3 less than the number of shoes in your child's closet (
**n**) - 8 more than the number of eggs in the refrigerator (
**n**) - some number (
**n**) reduced by the number of socks that are in your child's drawer (**r**) - the sum of the ages of all the children in your family (
**n**) divided by a number (**r**)

- some number (
