There are two Maths Early Learning Goals that children are assessed against at the end of their Reception Year. They are in Number and Space, Shape and Measure.
Number:
Children count reliably with numbers from 1 to 20, place them in order and say which number is one more or one less than a given number. Using quantities and objects, they add and subtract two single-digit numbers and count on or back to find the answer. They solve problems, including doubling, halving and sharing.
Space, Shape and Measure:
Children use everyday language to talk about size, weight, capacity, position, distance, time and money to compare quantities and objects and to solve problems. They recognise, create and describe patterns. They explore characteristics of everyday objects and shapes and use mathematical language to describe them.
Useful documents and videos
Here you will find a collection of videos produced by Oxford Owl which are particularly useful for understanding the Mathematics taught in Reception. Many more videos can be found on their YouTube channel: Oxford Owl - Learning at Home (see the link below).
