You can help your child to order numbers including fractions, decimals and percentages.
What you need:
- Newspaper, junk mail or old magazines
What to do:
Help your child to look for a collection of numbers and cut these out. Try to find numbers of a mixture of types, including decimals, fractions and integers.
Once you have a pile of numbers (10 to 15 would be plenty) put them in order from smallest to largest. Ask your child questions about the order of numbers as you work:
- Which is the smallest number?
- Which number is next smallest?
- What counting number is this number closest to?
- How can we tell which number is bigger if one is a fraction and one is a decimal?
Help your child to identify numbers that are missing from the sequence.
- What number would be one more than this one?
- What number would be one less than this one?
If you have found percentages, discuss how these can be included. A percentage needs to be a percentage of something, but you could treat all percentages as percentages of 1, so that for example 50% is equivalent to 0.5.
Add numbers that you did not find in the newspaper such as improper fractions or negative numbers.
