By the end of Year 1 most children should be able to:
Number

read numbers to 20 correctly

write numbers to 20 correctly

count objects up to 20 and always get it right

count reliably from 1 to 20 and place these numbers in the correct order.

given a number from 1 to 20, say the number that is one more and one less
Addition and Subtraction

using quantities and objects, add (+) and subtract () two single digit numbers e.g., 9 + 4, 7 – 3

count on (+) or back () to find the correct answer sometimes using a numberline

solve problems including doubling, halving, and sharing

understand and use the language involved in addition (more, makes, total, sum, add, altogether) and subtraction (take away, difference between, less, subtract, fewer, how many)
Shape, Space and Measure

use the correct names for ‘solid’ 3D shapes (sphere, cube, cuboid, pyramid) and ‘flat’ 2D shapes (circle, square, triangle, rectangle)

use correct mathematical language to describe these shapes e.g., faces, sides, corners, etc

use positional language correctly (behind, below, above, in front of, next to, between, inside, outside)

use everyday language to talk about size (larger, bigger, smaller) when comparing quantities and objects and solve problems

use everyday language to talk about weight (heavy, light, heavier than, lighter than) when comparing quantities and objects and solve problems

use everyday language to talk about capacity (full, empty) when comparing quantities and objects and solve problems

use everyday language to talk about distance (long, short, longer, taller, shorter) when comparing quantities and objects and solve problems

use everyday language to talk about time including days of the weeks and months of the year and begin to introduce time (e.g, faster, slower, earlier, later, o clock) and solve problems

use everyday language to talk about money (coins, pence, p, more than, less than) and solve problems

recognise, create and describe patterns
