KS1 Mathematics: Number and Place Value — Challenge
Greater-depth KS1 number and place value challenge: tricky counting, partitioning, sneaky comparisons, crossing 100, and open reasoning. Thirty minutes.
KS1 Mathematics: Number and Place Value — Challenge is a greater-depth activity book mapped to the DfE National Curriculum for Year 2, stretching learners beyond the core 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.

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.
