Step 14 The 8 times-table

Step 15 The 2, 4 and 8 times-tables

Pupils should be taught to:

• 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

• solve problems, including missing number problems, involving multiplication and division, including positive integer scaling problems and correspondence problems in which n objects are connected to m objects

## Length and perimeter

Pupils should be taught to:

• measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)

• measure the perimeter of simple 2-D shapes

## Fractions A

Pupils should be taught to:

• count up and down in tenths; recognise that tenths arise from dividing an object 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, 5/7 + 1/7 = 6/7 ]

• compare and order unit fractions, and fractions with the same denominators

• solve problems that involve all of the above

## Mass and capacity

Pupils should be taught to:

• measure, compare, add and subtract: lengths (m/cm/mm); mass (kg/g); volume/capacity (l/ml)

## Time

Pupils should be taught to:

• 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 and read time with increasing accuracy to the nearest minute; record and compare time in terms of seconds, minutes and hours; use vocabulary such as o’clock, am/pm, morning, afternoon, noon and 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]

## Shape

Pupils should be taught to:

• 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 2 right angles make a half-turn, 3 make three-quarters of a turn and 4 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
