About this resource and curriculum

Five friendly steps use numbers within 20 and a worked example on every page to practise number bonds to 10, number bonds to 20, adding a 2-digit number and ones, subtracting ones from a 2-digit number, and solving simple one-step word problems. Several questions are multiple choice so the focus stays on the method, and every step is auto-marked on screen with a full answer key, or the whole book can be printed to work through slowly on paper. The tone is warm and encouraging with no pass or fail language.

Study guidance and sample questions

Get the most from this

These five steps take addition and subtraction slowly, one skill at a time. You will practise bonds to 10, bonds to 20, adding and subtracting small numbers, then solve some simple stories. Read the tip first — it always shows you a worked example — then choose or type your answer. I’ll check it with you. There is no rush and no way to fail: just keep trying.

This is a supportive KS1 addition and subtraction workbook with smaller numbers and lots of scaffolding, built to grow confidence. Read each worked-example tip together, then let your child choose or type the answer. Keep it calm and positive — praise the effort and the correct thinking, and come back to the same steps another day. The answer key lets you check every question.

A scaffolded, differentiated-down support book for DfE KS1 addition and subtraction: number bonds to 10 and to 20, adding a 2-digit number and ones, subtracting ones from a 2-digit number (no carrying or exchanging), and simple one-step word problems. One skill per step, numbers kept within 20, plenty of multiple-choice inputs and a worked example in every tip, with a deliberately encouraging, no-pass/fail tone. All steps are auto-marked. Ideal for lower-confidence Year 1 learners or as a first pass before the core addition and subtraction book.

Every step is checked with the "Check my answers" button, which marks each response and gives friendly feedback. Several answers are multiple choice; the rest ask for a small number. Compare against the answer sheet for the full worked results, and re-try any step as often as you like.

How to study with KS1 Mathematics: Addition and Subtraction — Support

This parent guide relates the page examples with a structured study routine. The listed resource is labelled Mathematics, Key Stage 1, Year 1, Activity Book. Use that setting, the learning summary and published prompts to agree what effective work should show.

Prepare a focused session

Read the title and learning focus jointly. Ask the learner to predict the knowledge, terminology or plan they may need. Scan each sample and spot instruction words, values, signals, limits or less familiar terms. Agree a focused time window, remove interruptions and prepare useful materials such as paper, pencil, ruler, coloured pens, calculator, headphones or a device. Encourage an independent opening attempt so the attempt shows sound understanding and doubt. A quiet pause often strengthens remembering better than an immediate answer.

Make thinking published

Invite the learner to summarise the task in their own words. They can underline essential information, separate a larger problem into shorter steps, sketch a model, arrange details, rehearse a sentence or describe a planned method. Ask why their approach fits and whether another plan could work. When progress stops, offer a carefully scaled hint: state again the goal, point towards a useful example, reduce the choice, then model only the next step. Return control immediately afterwards. Spoken reasoning reveals mistakes and practises accurate subject language.

Check accuracy and understanding

Compare the attempt with published answer guidance after sustained effort. Inspect more than the final attempt: review the method, explanation, units, details, sequence, spelling or presentation where useful. Ask the learner to identify the opening point where their reasoning changed path. Complete corrections actively in a different colour or fresh space, followed by a concise account of the change. For a correct answer, ask for justification and one independent check. This separates confident knowledge from guessing while building accuracy, reflection and careful working habits.

Consolidate and extend

Finish with retrieval from memory. Cover the example and ask for the central idea, process or fact again. Create one small variation by adjusting a value, condition, example, viewpoint or level of support while keeping the learning focus. Invite the learner to write a comparable question and supply checking guidance. Record one success and one precise next step, perhaps reviewing terminology, practising a calculation, adding details or developing clarity. Recheck that target again in the week because spaced review gives clearer information than immediate repetition.

The interactive player, downloadable file and capture answer material retain their existing access controls. The guide strengthens preparation, discussion and review.
