Each number from 0 to 20 gets its own practice sheet built around six repeated activities: students say the number, color it, trace the numeral, find it among a grid of similar numbers, trace it again, and color a matching quantity of apples. The 'Find it' activity embeds the target number among several close distractors — for example, spotting 6 among 4, 7, 9, and 0 — while the apple-coloring task has students color the exact quantity the numeral represents. The same six-part layout repeats across all 21 numbers, building numeral recognition, counting, and one-to-one correspondence through a consistent routine at every level.
