What 1st Grade covers
First grade is where numbers stop being a rhyme and start being a tool. Children work with numbers to 100, learn that 34 means three tens and four ones, and build the addition and subtraction facts within 20 that everything later depends on. Alongside that they meet halves and quarters, measure with rulers and non-standard units, recognise coins, read a clock to the hour and half hour, name 2D and 3D shapes, and sort objects into simple categories. The exercises here follow that sequence, and most of them lean on pictures, number lines and counters — at this age seeing the maths matters more than writing it neatly.

Where children usually get stuck
Counting all instead of counting on
Asked to work out 8 + 3, many six-year-olds start again at one and count all eleven. It gets the right answer, so it is easy to miss. Watch for it, and practise starting from the larger number and counting on three — it is the step that makes mental addition possible.
Teen numbers written backwards
Fourteen sounds like "four" then "teen", so it often gets written as 41. This is a place-value gap, not carelessness. Ten frames and bundles of ten sticks fix it faster than correction does, because they show why the 1 comes first.
Subtraction as take-away only
If subtraction always means removing objects, "how many more does Ana need?" stops looking like subtraction at all. Introduce difference questions on a number line early, so the operation has two meanings from the start rather than one that has to be unlearned.
How to practise at home
- 1
Ten minutes, most days
Short and frequent beats long and occasional, especially for number facts. Ten focused minutes after school, four or five days a week, will do more for a 1st Grade child's fluency than an hour at the weekend — and it is far easier to keep going.
- 2
Ask for the method, not the answer
"How did you work that out?" is the single most useful question you can ask, and it is worth asking when the answer is right as well as when it is wrong. It shows you whether a correct answer came from understanding or from a lucky guess.
- 3
Use the kitchen and the shop
Doubling a recipe, working out change, reading a scale, timing something — these are the same skills the worksheets cover, with the advantage that they obviously matter. A child who resists a page of sums will often happily work out whether there is enough money.

Common questions
- What maths should a 1st Grade child know?
- The modules listed on this page are the standard objectives for 1st Grade (6-7) — they are what most primary curricula expect a child to cover during the year. Children move through them at genuinely different speeds, so treat the list as the shape of the year rather than a checklist with a deadline.
- How much practice is enough?
- For most children at this age, ten to fifteen minutes on most days is plenty. Regularity matters much more than volume: short sessions keep number facts fresh and keep maths from becoming something that only happens when there is a problem.
- Are these exercises free?
- You can browse every module on this page and open a free printable worksheet with an answer key without creating an account. A free account adds the full exercise library, progress tracking, and the ability to assign specific practice to your kids.
- Do these follow the school curriculum?
- The exercises are mapped to standard primary objectives for each year and grouped into the modules shown above. They are written to sit alongside most national curricula rather than to follow one country's exact sequence, so the topics will match even where the ordering differs.
