"Fill in the Missing Numbers: A Timed Worksheet With Pictures" is a worksheet that invites students to fill in the missing number in a set of three. A given number might be displayed at the beginning, in the middle, or at the end. In some cases, both the first and last numbers are given, and students have to fill in the middle number. Kindergarten pages focus on numbers 0-10, and first grade pages focus on numbers 0-100.

Each page features 10 groups of three images inside rectangles so students can see each set clearly. Each set of three contains the same images, but sets of images vary on each page. For example, students might fill in the numbers 25 and 27 on either side of 26 on a set of three turtles or the number 4 in between 3 and 5 on pictures of glue bottles.

The top of each page provides students with a spot where they can write their starting and ending times to see how long each page takes them to complete.

Memorizing the order of numbers and counting are essential skills that form the foundation of all other mathematical skills. Students can complete a variety of activities that enable them to practice counting.

Filling in the numbers on a number line is a good skill for beginners. As students become more proficient, you can have them fill in missing numbers. For example, the number line might show the numbers 3, 4, and 9. Students would fill in 0-2, 5-8, and 10. You can also ask students to order mixed-up number tiles from smallest to biggest, or biggest to smallest, for a challenge.

Older students can do similar activities with larger numbers. They can work with numbers to 100, 1,000, or even 1,000,000,000. Have students time their work, and you can see who needs more practice and which students are ready for a more challenging activity.
