An estimate is a given value, number or quantity that is near to the true amount.

A metre is a standardised unit of measurement.  We can abbreviate metre to m.

A centimetre is a standardised unit of measurement.  We can abbreviate centimetre to cm.

Estimate in metres and describe a metre in different ways

Maths

Measure length and height from zero using whole m or cm

Converting between metres and centimetres

Millimetres as a unit of measure and the relationship between them and cm

Measuring length and height using cm and mm

Converting between centimetres and millimetres

Estimate and measure lengths and heights and record in a table

Using graphs to represent lengths and heights

Solve problems involving length

Solve problems involving length and height

In this unit pupils will continue to measure using appropriate tools and units progressing to using a wider range of measures including comparing and using mixed units In the future unit pupil will learn perimeter as the distance around the edge of a 2D shape They will learn perimeter is measured in units of length found by counting units and by calculating by adding the side lengths of a 2D shape

In the prior unit pupils chose, used and compared appropriate standard units to estimate and measure length/height, mass, temperature, capacity to the nearest appropriate unit. In this unit pupils will continue to measure using appropriate tools and units progressing to using a wider range of measures, including comparing and using mixed units.

Measuring length and recording in tables

The difference is the result of subtracting one number from another.

When something is equivalent, it is equal in value.

When we convert, we change the unit of measurement between metres and centimetres, but the value remains the same.

A millimetre is a standardised unit of measurement.  We can abbreviate millimetre to mm.

When we can convert, we change the unit of measurement between millimetres and centimetres but the value remains the same.

A table is data arranged in rows and columns.

A collection of numbers, words, measurements and descriptions of things.

A column is a vertical arrangement of objects or numbers going up and down.

A row is a horizontal arrangement of objects or numbers going across.

A graph is a visual way of showing information. A Bar Graph uses bars of different lengths or heights to represent information.

An axis on a graph is a fixed measuring line that runs horizontally (left to right) and/or vertically from zero:

Data is a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.

When we interpret anything, including data, we explain its meaning.

A pictorial representation of a problem where bars are used to represent the known and unknown quantities.

Some but not all of something.  It is an amount or section which, when combined with others, makes up the whole.
