About this resource and curriculum

Challenges 1-4 hold sixteen auto-marked questions covering comparing standard units that do not match, telling the time to five minutes and working out time intervals, multi-step money problems including coin combinations and change, and two-step measures word problems. Challenge 5 is an open reasoning and extension task, asking learners to explain their thinking, test a mathematical claim, and design and solve their own word problem. A full worked answer key, including model answers and marking notes for the open task, is included alongside teacher, parent and pupil guidance.

Study guidance and sample questions

Get the most from this

Four tricky challenges plus one open task to really stretch your measurement thinking — unit comparisons, time intervals, multi-step money problems and measures word problems, then a chance to explain your reasoning and design your own problem. Use scrap paper for your working if it helps. Answer on screen and I’ll check Challenges 1-4, or print the book and work through it on paper.

This is a stretching KS1 measurement challenge book for a learner who is confident with the basics and ready to go further. Challenges 1-4 are self-marking and involve unit comparisons, time intervals and multi-step money and measures problems. Challenge 5 is open-ended, asking your child to explain their reasoning and design their own problem — a great one to talk through together. Allow around 30 minutes.

A greater-depth challenge book for DfE Year 2 measurement. Challenges 1-4 hold sixteen auto-marked questions requiring unit conversion (cm/m, g/kg, ml/litres), telling the time to five minutes, time intervals, and multi-step money and measures word problems. Challenge 5 is an open, non-auto-marked reasoning and extension task: explaining a mental method, testing a mathematical claim, and pupil-authored two-step word problem design. Useful for greater-depth provision, extension work or a maths challenge day.

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 and design task that is not auto-marked — check it against the model answers and marking notes on the answer sheet.

How to study with KS1 Mathematics: Measurement — Challenge

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

Prepare a focused session

Read the title and learning focus together. Ask the learner to predict the understanding, terminology or method they may need. Scan each sample and identify action words, amounts, hints, constraints or new terms. Agree a realistic time window, reduce interruptions and collect appropriate materials such as paper, pencil, ruler, coloured pens, calculator, headphones or a device. Encourage an self-directed first attempt so the work reveals secure understanding and gaps. A reflective pause often aids remembering better than an immediate answer.

Make thinking published

Invite the learner to describe the task in their own words. They can underline key information, separate a larger problem into smaller steps, draw a representation, sort support, rehearse a sentence or describe a planned method. Ask why their method fits and whether another method could work. When movement stops, provide a staged hint: repeat the goal, point towards a useful example, reduce the choice, then demonstrate only the next step. Return ownership directly afterwards. Spoken reasoning highlights misconceptions and practises correct subject language.

Check accuracy and understanding

Compare the attempt with published answer guidance after genuine effort. Inspect more than the final work: review the method, explanation, units, support, sequence, spelling or presentation where useful. Ask the learner to identify the first point where their reasoning changed path. Complete corrections actively in a different colour or fresh space, followed by a short note of the improvement. For a correct answer, request reasoning and one self-directed check. This separates secure understanding 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 main idea, process or fact again. Create one small alternative by changing a value, condition, example, viewpoint or level of support while keeping the learning focus. Invite the learner to write a similar question and supply checking guidance. Record one success and one clear next step, perhaps returning to terminology, rehearsing a calculation, adding support or refining clarity. Recheck that target later in the week because spaced review gives better information than immediate repetition.

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