How to teach counting a group of objects up to 20
- 1
Point to each object while counting aloud
Have your child touch each picture once while saying the number out loud, keeping their finger moving with their voice.
- 2
Count in a consistent path
Encourage counting left to right or top to bottom every time so no object gets skipped or counted twice.
- 3
Write the total number clearly
Once counting is finished, have kids write the final number in the answer blank rather than just saying it.
- 4
Recount to double-check bigger groups
For groups near 15 to 20, have kids count a second time to confirm the total before writing it down.
Common mistakes kids make
- Counting an object twice by losing track of which ones were already counted: use a finger or pencil tap to mark progress.
- Skipping objects at the edges of a cluttered picture: suggest circling each item as it's counted.
- Saying number names out of order past ten, such as 'eleven, twelve, twenty': practice the teen numbers separately if needed.
- Writing the wrong final digit after counting correctly out loud: have them say the total once more before writing.
Tips for parents and teachers
- Use real small objects like buttons or blocks at home to warm up before the printable.
- Keep sessions to five or ten minutes since young learners tire quickly on counting tasks.
- Check answers with the included key right after finishing so mistakes are caught early.
- Praise the counting process, not just the correct total, to build confidence.
