Maths

Use knowledge of decimal place value to convert between and compare metres and centimetres

Explain that different lengths can be composed additively and multiplicatively

Use knowledge of decimal place value to solve problems in different contexts

Use knowledge of place value to calculate with decimal numbers up to and bridging one tenth

Round a decimal number with hundredths to the nearest tenth

Round a decimal number with hundredths to the nearest whole number

Read and write numbers with up to 3 decimal places

Compare and order numbers with up to 3 decimal places

In this unit pupils will use their knowledge of decimal place value to convert between and compare metres and centimetres explaining that different lengths can be composed additively and multiplicatively.  In the future unit pupils will explain represent and compare whole pounds and pence.  They will convert quantities of money between pounds and pence and find change. 

In the prior unit pupils identified hundredths as part of a whole and described and represented hundredths as a decimal fraction. They compared and ordered decimal numbers with hundredths. In this unit pupils will use their knowledge of decimal place value to convert between and compare metres and centimetres explaining that different lengths can be composed additively and multiplicatively.

In this unit pupils will use their knowledge of decimal place value to convert between and compare metres and centimetres explaining that different lengths can be composed additively and multiplicatively.
