**L4/1**Recognise and describe number patterns: continue sequences involving decimals 1.3, 1.6, 1.9, 2.2, etc

**L4/2**Recognise and describe number relationships including multiple, factor and square: 5 is factor of 20, 20 is multiple of 5

- http://www.khanacademy.org/math/arithmetic/factors-multiples/e/divisibility_0.5

**L4/3**Use place value to multiply and divide whole numbers by 10 or 100: 342 x 10 = 3420 2456 ÷ 100 = 24.56

**L4/4**Recognise approximate proportions of a whole and use simple fractions/percentages to describe these: simple equivalence between fractions, decimals and percentages

**L4/5**Convert mixed numbers to improper fractions and vice versa: 1¾ = 7/4 etc

**L4/6**Begin to understand simple ratio: girls to boys ratio = 2 to 3 so 20 girls means 30 boys

**L4/7**Use inverse operations: ‘undo’ two step operations, understand ‘balancing’ sums 20 + □ = 100 ÷ 4

**L4/8**Understand the use of brackets in simple calculations: brackets take priority in calculation (3 x 4) + 14 12 + 14 = 26

**L4/9**Recall multiplication facts up to 10 × 10 and quickly derive corresponding division facts: Gold Standard

**L4/10**Solve problems with or without a calculator: solve two step problems choosing appropriate operations, interpret calculator display of 4.5 as £4.50

**L4/11**Use and interpret coordinates in the first quadrant

**L4/12**Use efficient written methods of addition and subtraction: column addition, subtraction and of short multiplication and division: TU x U, HTU x U, HTU ÷ U

**L4/13**Add and subtract decimals to two places and multiply a simple decimal by a single digit: 36.2 x 8

**L4/14**Use the properties of 2-D and 3-D shapes: recognise most quadrilaterals, all triangles, oblique lines of symmetry, use terms horizontal, vertical, congruent

**L4/15**Reflect simple shapes in a mirror line: at 45 degrees to the mirror line, begin to use the distance of vertices from mirror line to reflect more accurately

**L4/16**Translate shapes horizontally or vertically and begin to rotate a simple shape or object about its centre or a vertex

**L4/17**Interpret, with appropriate accuracy, numbers on a range of measuring instruments: measure to within 2mm, measure acute and obtuse angles to nearest 5 degrees

- http://www.khanacademy.org/math/geometry/segments-and-angles/e/angle_types

**L4/18**Find perimeters of simple shapes and find areas by counting squares and part squares: begin to find areas shapes that need dividing into rectangles

**L4/19**Collect, record and group discrete data: test a hypothesis about the frequency of an event (how many 6s in 50 throws of a die), record using frequency table

**L4/20**Continue to use Venn and Carroll diagrams to record their sorting and classifying of information: sorting numbers ‘multiples of 8’ and ‘multiples of 6’

**L4/21**Construct and interpret frequency diagrams and simple line graphs: interpret simple pie charts, scale on bar graphs reading between the labelled divisions etc

**L4/22**Understand and use the mode and range to describe sets of data:mode = most common, range = highest – lowest

**L4/23**Understand the language of probability: more likely, equally likely, fair, unfair, certain, impossible etc
