Grade 1 Before and After Numbers Math Worksheet

ABOUT THE WORKSHEET

Developing a strong foundation in number sense is a critical milestone for first-grade students. This "Before and After" worksheet focuses on helping learners understand the sequential relationship between numbers. By identifying the value that immediately precedes and follows a central number, children reinforce their understanding of basic addition and subtraction concepts (n-1 and n+1) without even realizing they are doing arithmetic. This specific worksheet provides ample practice with numbers ranging from 1 up to 10, ensuring mastery of basic single and double-digit sequences through repetition and pattern recognition.

• Math Topic: Counting & Number Sequences
• Question Count: 45 practice problems arranged in three columns
• Format: High-quality, easy-to-print PDF worksheet
• Skills Covered: Sequencing, counting forward and backward, and number recognition

STEP-BY-STEP SOLVED EXAMPLES

Example 1: Working with the Number 2

To find the number that comes before 2, we subtract 1 (2 - 1 = 1). To find the number that comes after 2, we add 1 (2 + 1 = 3). Filling in the empty boxes around the central 2 results in the sequence: 1, 2, 3.

Example 2: Working with the Number 10

Think about counting up to ten. What number do you say just before you reach 10? That number is 9. What is the next number in the counting sequence after ten? That number is 11. The completed set is: 9, 10, 11.

Example 3: Working with the Number 5

If you look at a classroom number line and locate the digit 5, the digit immediately to its left is 4, and the digit immediately to its right is 6. When you fill in the boxes on your worksheet, the full sequence reads: 4, 5, 6.

TEACHER & PARENT TIPS

When introducing this worksheet to your students, encourage them to use a physical number line or a desk tape if they find themselves getting stuck. For visual and kinesthetic learners, jumping along a giant number line drawn on the floor helps internalize the concept of "before" and "after" through physical movement. You can also play quick verbal games like "I'm thinking of a number" during transitions to make counting practice fun and interactive. Another great strategy is to use physical manipulatives like counting bears or blocks to show the increase or decrease in value as you move across the sequence boxes.
