A plain-English guide to what's actually covered in Year 1, and what "secure" looks like by the end of it.

Year 1 is the first year of the National Curriculum proper, coming straight after the more play-based Reception year. The jump can feel bigger than it needs to — most of what's covered builds directly on counting and number sense children already have, just with more structure around it. Here's what's actually in the Year 1 maths curriculum, strand by strand.
Children learn to count to and across 100, forwards and backwards, starting from any number. They count in multiples of 2, 5 and 10, read and write numbers to 20 in both numerals and words, and work with "one more" and "one less" than a given number. By the end of the year, most children can also compare and order numbers to 20 using the language of "greater than," "less than" and "equal to."
This is where a lot of Year 1 time goes: number bonds and related subtraction facts within 20 (knowing that 7 + 5 = 12 without recalculating each time), adding and subtracting one-digit and two-digit numbers to 20, and solving simple missing-number problems (7 = ? − 9). The aim is fluency with small numbers, not written methods yet — most of this is done mentally or with objects and pictures.
Formal times tables don't start until Year 2, but Year 1 lays the groundwork: counting in 2s, 5s and 10s, solving simple problems involving doubling, halving and sharing, using objects, arrays and pictures to represent grouping and sharing.
Just two ideas at this stage: recognising, finding and naming a half and a quarter of an object, shape or quantity — half an apple, a quarter of a group of counters. It's entirely concrete; formal fraction notation comes later.
Children compare, describe and solve problems for length and height, mass and weight, capacity and volume, and time — including telling the time to the hour and half past, and knowing the days of the week and months of the year. They recognise and know the value of different coins and notes, and learn to name common 2D and 3D shapes and describe simple positions and movements (left, right, above, below).
A few things trip up otherwise confident Year 1 children fairly often: reversing digits when writing numbers (writing 21 as 12, or 6 as a backwards shape), counting on from 1 every time instead of counting on from the larger number, and confusing "more" and "less" under pressure even when they clearly understand the concept out loud. None of these are cause for concern on their own — they're a normal part of number sense settling in — but if the same one keeps showing up weeks apart, it's worth a closer look rather than assuming it'll simply resolve itself.
Grasp Maths tracks each of these skills separately as your child practises — not just "Year 1 maths" as one score, but number bonds, counting patterns, and shape recognition as distinct, trackable strands — so if one specific thing needs a bit more attention, it's easy to see exactly which one.
