NUMBERS • ORDERING NUMBERS 23

Ascending and descending order

When we put things in order, sometimes we want to put

the largest number first, and sometimes the smallest.

TRY IT OUT

In a maths test,

there were 100

questions. Amira got

94 correct; Bella got 45;

Claudia got 61; Danny

got 35; Ethan got 98;

Fiona got 31; Greta got

70; and Harry got 81.

Mum^37

Trevor the gerbil^1

Dad^40

Grandpa^67

Buster the dog^7

Grandma^68

Uncle Dan^35

Anna (my sister)^13

When we order the

scores from lowest

to highest, we call it

ascending order.

When the scores

are listed from

the highest to the

lowest, we call it

descending order.

All in order

Practise your ordering skills by putting

this list of ages in ascending order. Why

not make an ordered list based on your

own friends and family? You could

order them by age, height, or the day

of the month of their birthday.
