### 'Working Hard, Aiming High'

# Year 4

These are the key skills that each child will be working towards in Year 4.

*By the end of year 4, children should be able to confidently:*

- Locate 4 and 5 digit numbers on a landmarked line and use this to compare and order numbers; round to ten, a hundred and a thousand.
- Understand the numbers of 1s, 10s, 100s, 1000s and 10,000s in a 5-digit number and the use of zero as a place holder.
- Know that one-place decimal numbers represent ones and tenths e.g. 3.7 = 3 ones and 7 tenths.
- Count in steps of 2, 4, 5, 10, 50, 100 and 1000.
- Recognise negative numbers in relation to number lines and temperature.
- Add multiples of 1, 10, 100, 1000 without difficulty, e.g. 15,347 + 3000, 434 + 300 and 648 – 220
- Mentally add and subtract any pair of two digit numbers.
- Know how to use the written addition: first expanded method, moving onto concise method. e.g. 300 80 5 385

300 40 6 346

100 10 11 *(**these are the ‘carry’ digits**)*

__700 30 1__ __731__

- Subtract 3 digit numbers from 3 digit numbers using ‘Frog’ and counting up, e.g. 426 – 278 by hopping along a line from 278 to 426

- Use Frog to subtract from multiples of 1000 where the difference is less than 500

- Multiply 1 and 2 digit numbers by 10, 100 and 1000; divide 1 and 2 digit numbers by 10 and 100 to understand place value in decimal numbers with one place.
- Know and recite 2x, 3x, 4x, 5x, 9x, 10x times tables incl. division facts up to 12th multiple; include multiplying by 0 (e.g. 5 x 0 = 0, 7 x 0 = 0) or by 1 (e.g. 5 x 1 = 5, ½ x 1 = ½).
- Multiply 1- digit numbers by 2-digit or friendly 3-digit numbers using grid method.
- Know how to use ‘efficient chunking’ for division above the range of the tables’ facts, e.g. 84 ÷ 6 = ?

Begin to extend this to 3 digit numbers, e.g. 145 ÷ 5 = ?

- Write the equivalent fraction for fractions with given denominators or numerators, e.g. ½ = ?/8; reduce a fraction to its simplest form, e.g. 6/12 ≡ ½.
- Convert between units of measurement, e.g. cm to m, g to Kg and ml to L; convert between units of time and between analogue and digital times.
- Identify acute and obtuse angles, compare and order angles up to 180⁰.
- Interpret and present discreet data using bar charts and pictograms
