How to Use This Activity Pack
Begin with Worksheets 1 and 2. Ask the child to point to the complete group of ten before counting the extra dots. Use one worksheet per short session and add practical objects, such as counters or building bricks, whenever a visual model needs reinforcement.
Move to the quest, number-word and comparison pages when the child recognises most teen numerals. Keep the final check-up untimed. Celebrate strategies and revisit a skill with objects if an answer is not yet secure.
