One-to-one correspondence 1-5

Tips on how to use this exercise at home and at school.

One-to-one correspondence 1-5

Early math concepts


In this exercise, the child matches the number of objects to the number expressed verbally, then the number of fingers or prisms, and finally the number. The aim is for the child to form an idea of numbers in the range 0-5 and later 0-10 and to understand the interrelationship between numbers, naming and notation.


One-to-one correspondence 1-5

Why is this exercise important?
The exercise supports the development of early numerical ideas. The aim is for the child to develop an idea of numbers in the range 0-5 and later 0-10 and to understand that the quantity ☻☻☻ can be represented as / / /, corresponding to the word "three" and the notation 3 and, of course, vice versa  i.e. the relationships between quantity, its naming and numerical notation.

Who is the exercise suitable for?
In general, it belongs to preschool or early school games. In addition to the concepts of number ideas, and rational assumptions, it also develops language skills at the same time. Part of the children solve the task intuitively and naturally, part of the children need to go through these tasks.

Methodological recommendations
Either read aloud the instructions to the child, play them from the app or let the child read them by themselves.

In the settings, we can customize the exercise:

  • Set the combination of pictures, symbols, fingers, prisms, sounds and numbers.
  • Setting the number range 0-5 or 0-10

The child hears the number first and gradually finds the correct pattern for it. She matches the answers by dragging the pictures, symbols, fingers, prisms, sounds and numbers in the right column so that everything matches the pattern in the left column. It depends on the settings we have chosen.

Tips for similar activities outside the app
For this activity, we can use finger countdown in natural situations. For example, physically matching a finger to an object, or prompting the child to remember how many horses were in the paddock, for example. The child has to mentally recall the situation and use the fingers as symbols to express the number.

It is also a great help to play memory games, and quartet and match the number with sounds, counts and so on.
