# Maths

## Year 3 Maths

## Autumn Term

In mathematics this term we will be studying the following topics:

**Place value and number**: understanding place gives value to the digits we use; ordering numbers; using number facts to add/subtract, including bridging tens; adding two 2-digit numbers; adding/subtracting near multiples of ten; multiplication and division facts for the 2, 3, 5 and 10 times tables; multiplication and division grouping; using double/near double number facts to speed up calculations; find 1, 10, 100 more/less than a given number.

**Fractions: **ordering/finding fractions of shapes and numbers.

**Length: **measuring using centimetres, metres, kilometres.

**Time: **use units of time to begin to tell the time to nearest five minutes on digital/analogue clocks.

**Shape: **naming 2D shapes and discovering the different lines of symmetry.

**Handling data: **collecting and displaying information to do with time – especially days/months/weeks.

**Problem Solving: **emphasis on reading for meaning and explaining the processes involved in solving word problems.

## Spring Term

· Addition

· Subtraction

· Multiplication

· Division

· Mental arithmetic

· Place value

· 3D shapes

· Capacity

· Time

· Data handling

## Summer Term

Use function machines to multiply by 2, 3, 4, 5 and 8 and understand the inverse; use scaling to multiply heights and weights by 2, 4, 8, 5 and 10; use known facts to multiply multiples of 10 by 2, 3, 4 and 5; multiply numbers between 10 and 30 by 3, 4 and 5 using the grid method; multiply 2-digit numbers by 3, 4, 5 and 8 using the grid method

Use the grid method to multiply 2-digit numbers by 3, 4, 5, 6 and 8; estimate products; divide using chunking, with and without remainders; decide whether to use multiplication or division to solve word problems; recognise tenths and equivalent fractions; find one-tenth and several tenths of multiples of 10 and begin to find one-tenth of single-digit numbers
