Place Value and Whole Numbers

What the page covers

The resources start with the basics of number. The mind map Counting lists skills such as counting to 20, placing numbers in order and saying what is one more or less than a number. Quizzes such as Review numbers to 1,000 ask pupils to write numbers in words, like nine hundred and fifty-four.

Further along, you will find work on rounding, estimating and operations with whole numbers. The mind map Whole numbers sets out the rounding rule: look at the digit in the next place, round down if it is smaller than 5 and up if it is 5 or more. Another mind map on rounding shows a worked example of a number rounded to the nearest hundred.

Where to start

1. Begin with Counting if you are working on early number sense.
2. Move to Review numbers to 1,000 to check reading and writing numbers.
3. Use the place value quizzes and flashcard decks to practise digit values and ordering.
4. Try Working with Whole Numbers (multiple choice) L1 for word problems on adding and subtracting large numbers, such as car mileage.

Bounds and rounding

Older students can go to Upper and Lower Bounds, a quiz that asks for the bounds of a number rounded to the nearest unit. The note Bounds (upper and lower) gives a step-by-step method: find the level of accuracy, halve it to get the tolerance, then add and subtract it. Since GCSE Maths is mentioned in some resources, this is a useful place for those students to practise.

Using quizzes and maps together

Read a mind map first to see the whole idea on one screen. Then take a quiz on the same topic and note where you slip. Go back to the map for that branch, and use a flashcard deck such as Rounding Whole Numbers to fix the vocabulary and rules.

Where this unit fits

This unit sits in the Number strand of Mathematics. Whenever you are ready, open a quiz, then make a mind map of your own to sum up what you learned.
