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.
