In Reception, maths centres around number, shape, space, measure and problem solving. Children will learn to count reliably up to 20, placing numbers in order and saying what is one more or one less than a given number. Using quantities and objects, they will be able to add and subtract two small numbers. Children will solve problems such as doubling, halving and sharing and use everyday language about size, weight, capacity, position, distance, time and money. They will recognise, create and describe patterns, exploring characteristics of everyday objects and shapes and using mathematical language to describe them.
