About this resource and curriculum

Challenges 1-4 are auto-marked and cover counting in tricky steps such as 3s and from non-multiples of ten, partitioning two-digit numbers and finding digit values, comparing and ordering tricky numbers including building the greatest and smallest number from given digits, and one more/one less across boundaries including the crossing into the hundreds. Challenge 5 is an open reasoning task with no single right answer, asking learners to explain their thinking clearly and spot a common misconception. A full worked answer key, including reasoning notes for the open challenge, is included alongside teacher, parent and pupil guidance.

Get the most from this

Ready for a challenge? This book pushes your number and place value thinking further, with tricky counting steps, partitioning, sneaky comparisons, and numbers that cross into the hundreds. Challenges 1-4 are marked for you straight away. Challenge 5 has no single right answer — write a clear explanation in full sentences so someone else could understand your thinking. Answer on screen or print the book and work through it on paper.

This is a greater-depth KS1 number and place value challenge book, going beyond our standard Quick Burst practice. Challenges 1-4 are self-marking and cover trickier counting, partitioning and comparing. Challenge 5 is an open reasoning task best talked through together, as there is no single correct answer — it is designed to stretch a confident learner’s thinking. Allow about 30 minutes.

A greater-depth challenge book for DfE KS1 number and place value, suitable for stretch and challenge or greater-depth groups. Challenges 1-4 hold sixteen auto-marked questions on counting in 3s and from non-multiples of ten, partitioning and digit value, comparing/ordering tricky numbers including building the greatest/smallest number from given digits, and one more/one less across the boundary into the hundreds. Challenge 5 is an open reasoning task targeting the misconception that crossing a boundary only changes one digit rather than triggering an exchange.

Challenges 1-4 are checked together with the "Check my answers" button, which marks each response and gives instant feedback. Challenge 5 is an open reasoning task that is not auto-marked — check it against the model answers and reasoning notes on the answer sheet.

How to study with KS1 Mathematics: Number and Place Value — Challenge

This parent guide relates the page examples with a practical study routine. The current resource is labelled Mathematics, Key Stage 1, Year 2, Activity Book. Use that framework, the learning summary and published prompts to decide what sound work should show.

Prepare a focused session

Read the title and learning focus side by side. Ask the learner to recognise the understanding, terminology or method they may need. Scan each sample and recognise action words, amounts, clues, constraints or unfamiliar terms. Agree a manageable time window, remove diversions and gather useful tools such as paper, pencil, ruler, coloured pens, calculator, headphones or a device. Encourage an self-directed first attempt so the response reveals sound understanding and uncertainty. A brief pause often aids remembering better than an immediate answer.

Make thinking shown

Invite the learner to restate the task in their own words. They can underline essential information, divide a larger problem into smaller steps, make a representation, sort evidence, rehearse a sentence or describe a planned method. Ask why their method fits and whether another strategy could work. When movement stops, offer a staged hint: rephrase the goal, point towards a related example, reduce the choice, then demonstrate only the next step. Return control directly afterwards. Spoken reasoning exposes mistakes and practises correct subject language.

Check accuracy and understanding

Compare the attempt with shown answer guidance after sustained effort. Inspect more than the final response: review the method, explanation, units, evidence, sequence, spelling or presentation where related. Ask the learner to find the first point where their reasoning changed course. Complete corrections actively in a different colour or fresh space, followed by a brief account of the change. For a correct answer, ask for justification and one self-directed check. This differentiates confident understanding from guessing while developing accuracy, reflection and careful working habits.

Consolidate and extend

Finish with retrieval from memory. Cover the example and ask for the main idea, process or fact again. Create one small alternative by altering a value, condition, example, viewpoint or level of support while keeping the learning focus. Invite the learner to write a related question and supply checking guidance. Record one success and one precise next step, perhaps reviewing terminology, rehearsing a calculation, adding evidence or improving clarity. Recheck that target later in the week because spaced review gives better information than immediate repetition.

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