Numbers 0 to 20, one page each, and every page does four jobs: follow the step-by-step strokes, count the pictures, trace the numeral, write the number word. Each page opens with a step-by-step strip that builds the numeral one stroke at a time, with a numbered red dot where the pencil starts, an arrow for the direction, and a label under each step: green "keep going", or red "lift your pencil" (only 4 and 5 lift). Then comes a count-them box with exactly that many pictures, a ten frame (two for the teens), dotted numerals to trace, an empty line to write alone, and the number word to trace. ALSO INSIDE • Grown-up guide: the four writing lines and six things that work • Numbers-I-can-write chart for the fridge • Certificate Big 1⅛″ pre-K lines for the numerals, ¾″ lines for the words — ages 3–5. Clean schoolbook print font (Edu SA Beginner). FOUR FILES: US Letter and A4, each in a standard and an Ink Saver edition. Slip a page into a sleeve and use a dry-erase marker to practice again.
