A decimal number has a decimal point followed by digits that show the fractional part.

An equation is used to show that one number, calculation or expression is equal to another.

Factors are numbers which divide exactly into another number.

The product is the result of two or more numbers multiplied together.

Explain that decimal numbers with tenths can be composed multiplicatively

Maths

Explain that decimal numbers with tenths can be composed additively

Use known facts and mental strategies to calculate with decimal numbers within and across a whole

Use knowledge of column addition and subtraction to calculate with decimal numbers

Use representations to round a decimal number with tenths to the nearest whole number

In this unit pupils will calculate with decimal numbers using column addition and subtraction. In the future unit pupils will identify hundredths as part of a whole and describe and represent hundredths as a decimal fraction. They will compare and order decimal numbers with hundredths.

In the prior unit pupils identified tenths as part of a whole and describe and represented tenths as a decimal fraction. They counted tenths in different ways and compared and ordered decimal numbers with tenths. In this unit pupils will calculate with decimal numbers using column addition and subtraction.

In this unit pupils will extend their understanding of formal calculation strategies to use column methods to add and subtract with decimal numbers.
