"Counting By Ones Starting With Numbers One Through Nine" is a worksheet that helps students practice counting by ones. Each section starts by asking students to begin with a number 1 through 9. Then, they count by one, with pictures of counting fingers to help them. Each one corresponds to an addition problem that is listed below where students fill in the answer.

Each section starts simply by asking students to start counting from 1 or 2. Later sections ask students to start with higher numbers, like 8 or 9. It's a very visual way for students to experience important math concepts, like one-to-one correspondence and counting up, in early elementary grades.

Students must learn the basics of addition before they can tackle more complex addition problems. Allowing students to count on their fingers lets them see how addition is the same as counting.

For example, you can give them a math problem like 2 + 5. Students can practice starting with the number 2 and counting up to five digits (3, 4, 5, 6, 7) to get to 7. They can see how each of the 5 digits is represented by a different number. They can also see how math problems are related, like how 5 + 2 has the same answer as 2 + 5.
