Practice Counting in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Determining the total number of objects in a set by assigning exactly one number to each object in sequence, where the last number spoken equals the total count (the cardinality of the set).
Like pointing to each toy and saying '1, 2, 3...' to know how many toys you have.
Example 1
easyA student counts the dots on a domino. The left side has 3 dots and the right side has 4 dots. How many dots are there in total?
Example 2
mediumHow many letters are in the word MATHEMATICS? Count carefully — some letters repeat.
Example 3
easySkip-count by 5s starting at 5 and list the first six multiples.
Example 4
mediumA bag contains red, blue, and green marbles. There are 4 red, 3 blue, and 5 green marbles. Without counting the whole bag at once, use grouping to find the total.
