Rounding and Ordering Numbers

Challenge children to build on their growing understanding of the properties of number — and their ability to manipulate them — by ordering, rounding and estimating!

With the included slides and activities, children will learn about, then practise, ordering small and large numbers, ordering multiples of numbers, using rounding and estimating when working with measure and more!

Counting in Multiples

With the included slides, children are challenged to order given sets of two-, three- and four-digit numbers. They may then practise ordering numbers by completing and/or extending sequences with missing numbers.

Rounding Numbers

Explore how numbers can be rounded in a variety of ways, such as to the nearest ten, hundred or thousand. Children can then practise doing this either during the main activity, or if you prefer, by playing the included rounding numbers board game!

Representing Numbers

Building on children’s growing knowledge of the place value of digits in two-, three- and four-digit numbers by representing them in a variety of ways, including using symbols, pictures or money. They can then practise these skills during either of the two included activities.

Estimating

In this, the fourth of five lessons in the ‘Rounding and Ordering Numbers’ Complete Series, children may begin to consolidate the skills they have developed by estimating, rounding and ordering numbers when working with different measures such as grams and kilograms or millilitres and litres.

Solving Problems!

Challenge children to apply their knowledge of ordering numbers — including ordering multiples of numbers — and estimating and rounding by working independently or together to solve a variety of problems.
