# Great Activity in Groups with Numbers

## Group Activity & Discusion

Ask each group to discuss and agree on the meaning of a number and ways of describing it or where it's used. This is good to bring the use of English into maths e.g. the spellings of their write up, also good for verbal feedback to the rest of the class. They should also think about things like Prime Numbers, sequences such as the Fibonacci sequence, Odds, Evens, Prime, Real, Integers, Natural, Whole numbers and so on. Don't forget the effect of using the number in calculations and certain patterns that occur when using the number. You may have even more ideas.

The numbers to use are:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Below are some of the ideas my students have discussed and agreed on. Can you or if you're a teacher can your class come up with more
