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

Maths

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.

Use knowledge of decimals to solve problems in different contexts: length

Something is common when it is frequently used or it occurs regularly.

Larger numbers can be composed of smaller numbers.

The act of splitting an object or value down into smaller parts.

Explain that different lengths can be composed additively and multiplicatively

A multiple is the result of multiplying a number by an integer.

The act of breaking an object or value down into smaller parts.

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

A mental strategy which uses addition or subtraction to cross a number boundary.

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

The name we give to one part of one hundred equal parts.

The name we give to one part of ten equal parts.

The process of unitising and exchanging between place values.

Use knowledge of column addition and subtraction to calculate with decimals: tenths and hundredths

A multiple is the result of multiplying a number by an integer. For example 2 × 5 = 10 so 10 is a multiple of 2 and 5.

Something that comes before something else is known as the previous thing.

Something that comes after something else is known as the next thing.

Rounding means making a number simpler but keeping its value close to what it was.

Round a decimal number with hundredths to the nearest tenth

Round a decimal number with hundredths to the nearest whole number

One thousandth is one part in one thousand equal parts.

When a whole is divided into one thousand equal parts, we can say one of those parts is one thousandth the size of the whole.

The thousandths column places the number of thousandths a given number has.

A millimetre is a measure of length that can be abbreviated as mm.

Read and write numbers with up to 3 decimal places

When you compare, you look for similarities and differences in an object or value.

The value of a digit in a number based on where it is placed is known as place value.

You can order numbers by putting them in a place based on a set rule.

Compare and order numbers with up to 3 decimal places

A representation is a way of showing a mathematical idea. Concrete objects, pictures and symbols can all be used to represent mathematics.

A mathematical process such as addition, subtraction, multiplication or division can be described as an operation.

An efficient strategy is a way of solving a problem that is accurate and can be done more quickly than others.
