About Counting & Number Order
Counting and number order skills form the foundation of mathematical understanding. Students learn to count forwards and backwards, identify numbers that come before, after, or between given numbers, understand the sequential nature of our number system, and develop number sense through pattern recognition.
Strong counting skills are essential for all future math learning. Understanding number order helps with addition, subtraction, place value, measurement, and data. Skip counting builds the foundation for multiplication, while comparing numbers develops critical thinking about quantity and magnitude.
Counting & Number Order
Count to 120, fill missing numbers, and compare two-digit numbers using place value and <, >, =.
This hard level worksheet:
Skip-count by 2s/5s/10s from non-zero starts and justify two-digit comparisons with tens/ones.
Key Concepts
- Count forward/backward within 120
- Place value to compare two-digit numbers
- Complete and extend number patterns
Prerequisite skills
Count objects to 20; recognize tens and ones to 20.
Teaching Strategies
Use hundreds charts and open number lines; ask students to explain before/after; link skip-counts to coins (nickels/dimes).
Assessment ideas
Have students count forward and backward from different starting points. Give missing number problems in sequences. Ask students to skip count by various intervals. Use quick fluency checks. Show a section of hundreds chart and ask what numbers are hidden.
Common Challenges
Dropping numbers when counting back; reversing digits (e.g., 41/14); comparing by ones instead of tens first.
Real-World Applications
Counting calendar days, book pages, or small money amounts.
Extension Activities
Create missing-number puzzles to 120; ask students to invent a pattern and have a partner identify the rule.
Parent Tips
Practice short counts on walks, ask for before/after numbers, and sort coins or cards to make tens/ones.
