·          Choose an appropriate strategy to solve a calculation based upon the numbers involved (recall a known fact, calculate mentally, use a jotting, written method)

·          Understand that division is the inverse of multiplication and vice versa

·          Write and calculate mathematical statements for multiplication and division using the multiplication tables that they know, including for two-digit numbers times one-digit numbers, using mental and progressing to formal written methods

·          Use estimation to check answers to calculations and determine, in the context of a problem, an appropriate degree of accuracy

·          Solve problems, including missing number problems, involving multiplication and division (and interpreting remainders), including positive integer scaling problems and correspondence problems in which n objects are connected to m objects

Measures
Number – fractions Geometry – properties of shapes ·   Measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)

·   Continue to estimate and measure temperature to the nearest degree (°C) using thermometers

·   Understand perimeter is a measure of distance around the boundary of a shape

·   Measure the perimeter of simple 2-D shapes

·   Tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks

·   Estimate/read time with increasing accuracy to the nearest minute

·   Record/compare time in terms of seconds, minutes, hours; use vocabulary such as o’clock, a.m./p.m., morning, afternoon, noon, midnight

·   Know the number of seconds in a minute and the number of days in each month, year and leap year

·   Compare durations of events [for example to calculate the time taken by particular events or tasks]

·   Continue to recognise and use the symbols for pounds (£) and pence (p) and understand that the decimal point separates pounds/pence

·   Recognise that ten 10p coins equal £1 and that each coin is of £1

·   Add and subtract amounts of money to give change, using both £ and p in practical contexts

·   Solve problems involving money and measures and simple problems involving passage of time

·   Show practically or pictorially that a fraction is one whole number divided by another (e.g. can be interpreted as 3 ÷ 4)

·   Understand that finding a fraction of an amount relates to division

·   Recognise that tenths arise from dividing objects into 10 equal parts and in dividing one-digit numbers or quantities by 10

·   Recognise, find and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators

·   Recognise and use fractions as numbers: unit fractions and non-unit fractions with small denominators

·   Recognise and show, using diagrams, equivalent fractions with small denominators

·   Add and subtract fractions with the same denominator within one whole [for example, + = ]

·   Compare and order unit fractions, and fractions with the same denominators (including on a number line)

·   Count on and back in steps of , and

·   Solve problems that involve all of the above

·   Draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them

·   Recognise angles as a property of shape or a description of a turn

·   Identify right angles, recognise that two right angles make a half-turn, three make three quarters of a turn and four a complete turn; identify whether angles are greater than or less than a right angle

·   Identify horizontal and vertical lines and pairs of perpendicular and parallel lines

Geometry – position and direction
·    Describe positions on a square grid labelled with letters and numbers
