step 1 of 6
Leo and Mia have a garden patch at Meadow Lane. Strawberry plants grow in the first row.
Leo touches each plant one time and says one number. Count with him. How many plants?
Tap each dot and count out loud.
One-to-one counting
One-to-one correspondence when counting objects: each object is paired with exactly one number name
What a learner can do afterwards
- 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
1 · Read
When you count, every thing gets exactly one number. Touch it, say the number, move on. If you count a thing twice, your count comes out too big. If you skip a thing, your count comes out too small.
Tap each star and count out loud.
Try it together
Leo counts his apples. He touches each apple one time and says 1, 2, 3, 4. Four apples.
Tap each apple and count out loud.
Good to know
If you touch a thing twice, it gets two numbers, and the count comes out too big. If you skip a thing, it gets no number, and the count comes out too small. One touch, one number.
One thing, one number. Never skip, never count twice.
