24 one-step word problem cards for Year 1, all within 20. Each card has a short story with the numbers in bold, a picture that shows exactly those numbers, and a thinking bubble with a strategy to try. Children show their answer in two ways on the recording sheet.

WHAT’S INSIDE (11 pages)
• 24 challenge cards, 4 per page, with cut lines
• A “Ways to show it” poster – drawing, ten frames, number line, part-whole model and bar model
• A recording sheet – two ways and a number sentence for each card
• Answers with the number sentence for every card
• How to use the cards, with ideas for the maths area, early finishers and small-group reasoning

THREE LEVELS
• ★ Cards 1–8, within 10 – adding, taking away, the missing part of 10, comparing
• ★★ Cards 9–16, within 20 – bridging 10, using known facts, doubles, the difference
• ★★★ Cards 17–24 – missing numbers, comparing with a bar model, finding all the ways, and spotting a mistake
