Counting Back Year 1 Maths Unit

Build confident subtraction thinking with a complete Year 1 unit focused on counting back within 20. Students learn to identify the starting number, use the second number as the number of backward steps, say the preceding numbers in order and record the number they land on as the difference.

The editable 27-slide lesson explains the strategy with worked examples, guided questions and practice prompts. Printable resources include a display, student reference, number-line activity, race game, five worksheets, matching red-answer pages, an assessment with answers and a five-level rubric.
