One-to-one counting
One-to-one correspondence when counting objects: each object is paired with exactly one number name
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
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.
Practice this concept
A short Gakuva activity you can use without signing in.
Counting objects practice
Touch each object once and choose the total across four short counting sets.
Practice answers and completion are not saved. Parent observation remains the lesson record.
Learning resources
Reviewed external links that reinforce this concept. They do not replace Gakuva’s teaching approach.
Teddy Numbers
Select individual treats to build a requested quantity. For one-to-one practice, have the learner touch each chosen treat and count aloud.
Proof: Save a screenshot plus an adult note or short recording that the learner touched each treat once while counting aloud without skips or repeats.
Underwater Counting
Supplemental counting-and-numeral matching with focused levels to 5 or 10; the game does not enforce touching every object once.
Proof: Save a screenshot plus adult observation of the learner pointing to each creature once while counting aloud.
Number Frames
Adult-guided virtual manipulative: drag one counter into each frame cell and say one number for every counter.
Proof: Use the built-in snapshot plus adult observation or audio of the learner counting each counter exactly once.

This concept
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?”
