Glossary

Average; The average of many numbers is the number

in the middle. Example; if you have a 1 year old and a

10 year old their average age is 5 years old (because 5

is right in the middle).

Approximately; Approximately means “not exactly.”

If a backpack weighs 4.5 kilograms, you can say that it

weighs approximately 5 kilograms.
