ABOUT THE WORKSHEET

The "Continue the Number Sequence" worksheet is an essential educational resource designed to develop early numeracy and number sense in young learners. This activity focuses specifically on counting forward by ones, which is a foundational skill for students in Grade 1 and early Grade 2. By identifying the pattern in the first three numbers of each row, students learn to predict and write the subsequent values in the sequence correctly. This repetitive practice helps build cognitive speed and accuracy, ensuring children are comfortable moving between tens and navigating the transitions from numbers like 19 to 20 or crossing the 100 mark.

QUICK DETAILS

STEP-BY-STEP SOLVED EXAMPLES

Example 1

Problem: 64, 65, 66, __, __, __, __, __, __, __

Step: Identify the pattern. Each number increases by one. Start at 66 and count forward.

Solution: The next numbers are 67, 68, 69, 70, 71, 72, 73.

Example 2

Problem: 19, 20, 21, __, __, __, __, __, __, __

Step: Count forward by one starting from 21. This helps practice crossing into the twenties.

Solution: The next numbers are 22, 23, 24, 25, 26, 27, 28.

Example 3

Problem: 98, 99, 100, __, __, __, __, __, __, __

Step: Transition from the double-digit 99 to the triple-digit 100 and continue the count in the hundreds.

Solution: The next numbers are 101, 102, 103, 104, 105, 106, 107.

TEACHER & PARENT TIPS

To help students succeed with number sequences, encourage them to use a hundreds chart as a visual guide if they get stuck. For students who finish early, challenge them to count backward from the starting number or count by twos instead to increase the difficulty. Practicing oral counting alongside written work reinforces the auditory-visual connection of number names and symbols. Finally, always have students read their completed sequences aloud; hearing the rhythm of the numbers often helps them catch any skipped numbers or transcription errors automatically.
