A Math Toolbox in Every Home
As teachers, we know the value of hands-on exploration with math manipulatives in school. We can extend the sense of discovery and empowerment into our students’ homes by helping them assemble math toolboxes to be enjoyed by the whole family.

Ratio and Proportion
A ratio is a comparison of two numbers. A proportion is a statement (or equation) that says two ratios are equal. If one number in a proportion is not known, cross-multiplying can be used to find the unknown number.

Decimals
Decimals, like fractions, are a way of writing numbers that are larger or smaller than whole numbers. Decimals are represented by a symbol called a decimal point.

Adding and Subtracting Fractions
To add or subtract fractions with the same denominator (like fractions), add or subtract the numerators, and write the sum or difference over the denominator. To add or subtract fractions with different denominators, find a common denominator and rewrite the fractions as like fractions.

Regrouping
We group numbers to make them easier to work with. Most of the time, one group of 10 or one group of 100 is easier to work with than ten 1’s or one hundred 1’s. Sometimes, however, numbers are easier to work with if we arrange them into different groups.

Explain Rounding and Estimating
