Let’s count slowly. Touch each object once and say one number for each touch.
Get 5 small objects. Line them up, have your child touch and count each one, then mix them up and count again. Start with 3 objects if needed.

Check understanding
- Point to or touch each object exactly once while saying number names
- Do not skip objects or double-count when counting a set
- Recognise an error when someone counts an object twice
“If your child is counting a pile of grapes, do they touch or point to each one exactly once as they say each number — without skipping any or counting the same one twice?”
