Maths Year 1 

Year 1 KPIs: 

Pupils will be able to:

• count to and across 100 forwards and backwards, beginning with 0 or 1, or from any given number

• count, read and write numbers to 100

• count in multiples of twos, fives and tens

• represent (including symbols) and use number bonds and related subtraction facts within 20

• recognise, find and name a half as one of two equal parts of an object, shape or quantity

Compare, describe and solve practical problems for:

• Lengths and heights (long/short, double/half)

• Mass/weight (heavy/light)

• Capacity and volume (full/empty)

• Time (quicker, slower, earlier, later)

• Tell the time to the hour and half past the hour and draw the hands on a clock face to show these times

• Recognise and name common 2-D and 3D shapes

Pupils will be able to:

• reason about addition 

• explain that when you add 0 to a number the number does not change

• explain if 2 numbers added together will total more or less than 10

• show that they know and can prove that repeated addition is the same as multiplication. (E.g., using an array or number line) 

• show that they know that: when counting in 10s from 0 the answer will always end in 0; when counting in 5s from 0, the number will end in 0 or 5; and, when they count in 2s from 0, the answer will always be even

• work out mental calculations such as: 2 numbers have a sum of 19 and a difference of 5 – what are they? 

• solve simple missing number box problems such as: 28 - __ = 11, 45 + __ = 57 

• recognise when a group of objects can be shared equally and when it cannot 

• solve word problems involving more than 1 step

• find a half of a shape number or quantity and explain that each part must be equal

• identify which of a selection of o’clock and half past times will occur next

• arrange containers of different sizes according to mass, or capacity

• spot 2d shapes in the faces of 3d shapes
