Boost your first grader's number sense with this number sequence worksheet. Students practice counting forward by ones from various starting points within 100.
ABOUT THE WORKSHEET
Developing a strong grasp of number sequences is a fundamental skill for young learners in early elementary. This worksheet is specifically designed for Grade 1 students to practice counting forward by ones. By starting sequences at various points within the 1-100 range, students build cognitive flexibility and spatial number line awareness. This resource helps transition children from simple rote counting to understanding the predictable patterns of our base-ten system. It is an ideal tool for reinforcing place value concepts and preparing for more complex addition and subtraction tasks later in the curriculum.

STEP-BY-STEP SOLVED EXAMPLES
Example 1: Starting at 64
The sequence begins with 64, 65, and 66. To find the next number, simply add 1 to 66. The next number is 67. Continue adding 1 until all empty boxes are filled: 67, 68, 69, 70, 71, 72, and 73.
Example 2: Crossing the Century (Sequence 5)
The sequence starts at 98, 99, 100. For the next number, we move into the hundreds place. Adding 1 to 100 gives us 101. The following numbers in the sequence would be 102, 103, 104, 105, 106, and 107.
Example 3: Starting at 19
Given the numbers 19, 20, and 21. Observe that the tens digit changes as we move from 19 to 20. Adding 1 to 21 results in 22. The sequence continues steadily: 23, 24, 25, 26, 27, and 28.
TEACHER & PARENT TIPS
When using this worksheet, encourage students to say the numbers out loud as they write them. This auditory reinforcement helps solidify the oral counting sequence in their memory. If a child gets stuck, provide a hundreds chart as a visual scaffold to help them find the "next door neighbor" of a number. For an extra challenge, ask students to identify whether the numbers in a specific row are odd or even, or have them try counting backwards from the last number they wrote. Using physical manipulatives like a number line or base-ten blocks can also help students visualize the "plus one" pattern happening in each sequence box.
