The mental strategies that turn counting into knowing. A Year 1 maths lesson on adding and subtracting within 20, ages 5 to 6. The lesson covers: joining equal groups and taking away; counting on and back along a number line; and the mental strategies children need — making ten, swapping the numbers round, and using known doubles. It finishes with a partner dice game, a missing-number activity and a closing quiz. Ready-to-teach PowerPoint, no prep.
