# Ordering Numbers

"Waiter, I would like a 7 and a 3, please..."

NO, not THAT type of ordering. We mean putting them in order ...

## Ascending Order

To put numbers in order, place them from lowest (first) to highest (last).

This is called "Ascending Order". Think of ascending a mountain.

Example: Place 17, 5, 9 and 8 in ascending order.

• Answer: 5, 8, 9, 17

Example: Place 3, 1, 19, 12, 9, 2 and 7 in ascending order.

• Answer: 1, 2, 3, 7, 9, 12, 19

## Descending Order

Sometimes you want the numbers to go the other way, from highest down to lowest, this is called "Descending Order".

Example: Place 17, 5, 9 and 8 in descending order.

• Answer: 17, 9, 8, 5

## Remembering

• Ascending: the "A" points upwards
• Descending is "Down"-sending

### Summary

 Ascending Descending "A" points up "D" for "Down"

## Practice

Practice by ordering your friends. Measure their heights, then place them in ascending order of height. Try it again, but use their weights.
