Calculation

Mental strategies

 Recall addition and subtraction facts for numbers to 20 and pairs of one-place decimals with a

total of 1, e.g. 0.4 + 0.6.

 Derive quickly pairs of one-place decimals totalling 10, e.g. 7.8 and 2.2, and two-place decimals

totalling 1, e.g. 0.78 + 0.22.

 Know and apply tests of divisibility by 2, 4, 5, 10, 25 and 100.

 Use place value and number facts to add or subtract two-digit whole numbers and to add or

subtract three-digit multiples of 10 and pairs of decimals, e.g. 560 + 270; 2.6 + 2.7; 0.78 + 0.23.

 Add/subtract near multiples of one when adding numbers with one decimal place, e.g. 5.6 + 2.9;

13.5 – 2.1.

 Add/subtract a near multiple of 10, 100 or 1000, or a near whole unit of money, and adjust, e.g.

3127 + 4998; 5678 – 1996.

 Use place value and multiplication facts to multiply/divide mentally, e.g. 0.8 x 7; 4.8 ÷ 6.

 Multiply pairs of multiples of 10, e.g. 30 x 40, or multiples of 10 and 100, e.g. 600 x 40.

 Double quickly any two-digit number, e.g. 78, 7.8, 0.78 and derive the corresponding halves.

 Divide two-digit numbers by single-digit numbers, including leaving a remainder.

Addition and subtraction

 Add two- and three-digit numbers with the same or different numbers of digits/decimal places.

 Add or subtract numbers with the same and different numbers of decimal places, including

amounts of money.

 Find the difference between a positive and negative integer, and between two negative integers in

a context such as temperature or on a number line.

Multiplication and division

 Multiply pairs of multiples of 10, e.g. 30 x 40, or multiples of 10 and 100, e.g. 600 x 40.

 Multiply near multiples of 10 by multiplying by the multiple of 10 and adjusting.

 Multiply by halving one number and doubling the other, e.g. calculate 35 x 16 with 70 x 8.

 Use number facts to generate new multiplication facts, e.g. the 17x table from 10x + 7x tables.

 Multiply two-, three- or four-digit numbers (including sums of money) by a single-digit number

and two- or three-digit numbers by two-digit numbers.

 Divide three-digit numbers by single-digit numbers, including those leaving a remainder and

divide three-digit numbers by two-digit numbers (no remainder) including sums of money.

 Give an answer to division as a mixed number, and a decimal (with divisors of 2, 4, 5, 10 or 100).

 Relate finding fractions to division and use them as operators to find fractions including several

tenths and hundredths of quantities.

 Know and apply the arithmetic laws as they apply to multiplication (without necessarily using the

terms commutative, associative or distributive).

Geometry

Shapes and geometric reasoning

 Classify different polygons and understand whether a 2D shape is a polygon or not.

 Visualise and describe the properties of 3D shapes, e.g. faces, edges and vertices.

 Identify and describe properties of quadrilaterals (including the parallelogram, rhombus and

trapezium), and classify using parallel sides, equal sides, equal angles.

 Recognise and make 2D representations of 3D shapes including nets.

 Estimate, recognise and draw acute and obtuse angles and use a protractor to measure to the

nearest degree.
