Every digit of a number has a fixed place, its place value.
In 347 the 3 is the hundreds, the 4 is the tens, and the 7 is the ones.
Example: Find all numbers with 6 ones.
You look for all numbers whose last digit is a 6, for example 126 or 416.
Circle all the matching numbers.
The circled numbers show the answer.

For parents
What does this exercise practice?
Distinguish digits by their place value and search numbers for a specific place.
Common pitfalls
Children mix up digit and place value: in 474 the 4 is once the hundreds and once the ones. Always ask at which place the digit stands.
How to practice at home
Look at house numbers or prices: where is there a 5? Is it the ones, the tens, or the hundreds?
