These worksheet pages invite students to practice counting by threes and fours. The very top of the page features a number line with the numbers students will be using on the worksheet. For example, if the page asks students to "Count by 4s," the numbers 4, 8, 12, 16, 20, 24, 28, 32, 36, and 40 will be listed at the top of the page.

The first activity asks students to trace the numbers. Then, they trace the first three numbers and write the next three numbers on the line. The numbers that they trace are different sizes, which supports fine motor skill development and makes the activity more engaging.

The last section features sets of three, four, or five images. One image in the set is blank, and the others are filled with numbers. Students have to fill in the missing number. For example, when counting by threes, students may see three fish. The first is labeled 12, and the last is labeled 18. They would write the number 15 on the blank fish.

Skip counting is an important skill for students to develop. It supports the development of counting skills, and it forms the foundation for multiplication.

There are many ways for students to practice skip counting in school. They can trace or fill in blank numbers, like writing the number 12 in a series of images that are labeled 9, ___, 15, and 18. Counting aloud as a class is a great way for students to practice skip counting by different numbers. A hands-on activity could include arranging a stack of number cards in the right order.
