Counting Examples in Math
Start with the recap, study the fully worked examples, then use the practice problems to check your understanding of Counting.
This page combines explanation, solved examples, and follow-up practice so you can move from recognition to confident problem-solving in Math.
Concept Recap
Determining the total number of objects in a set by assigning one number to each object.
Like pointing to each toy and saying '1, 2, 3...' to know how many toys you have.
Read the full concept explanation →How to Use These Examples
- Read the first worked example with the solution open so the structure is clear.
- Try the practice problems before revealing each solution.
- Use the related concepts and background knowledge badges if you feel stuck.
What to Focus On
Core idea: Counting establishes a one-to-one correspondence between objects and numbers.
Common stuck point: Confusing 'how many' with 'which number' (cardinal vs ordinal).
Sense of Study hint: Try touching or moving each object as you count it, then say the last number out loud — that's your total.
Worked Examples
Example 1
easySolution
- 1 Count the left side: 1, 2, 3 — there are 3 dots.
- 2 Count the right side: 1, 2, 3, 4 — there are 4 dots.
- 3 Count all dots together starting from 1: 1, 2, 3, 4, 5, 6, 7 — the total is 7 dots.
