Skip Counting by 10s from 0 to 120

Skip counting by 10s helps students recognize number patterns and build a strong foundation for understanding place value. It also develops fluency with addition and prepares students for working with larger numbers.

Counting Practice:
  • Start at 0 and count forward by 10s until you reach 120.
  • Say the numbers out loud while pointing to them: 0, 10, 20, 30 …
  • Practice beginning at different numbers such as 40 and continue counting by 10s.
Teaching Tip

Encourage students to tap, clap, or march with each number. Movement and rhythm reinforce the counting sequence and keep students engaged.

Recognizing Multiples of 10

Numbers that can be counted in groups of ten are called multiples of 10. These numbers always end with the digit 0.

Examples:
  • 30 is a multiple of 10 because we can count 10, 20, 30 in groups of 10.
  • 70 is a multiple of 10 because we can count 10, 20, 30, 40, 50, 60, 70 in groups of 10.
  • All numbers in the skip counting sequence—10, 20, 30, 40 …—are multiples of 10.
Helpful Strategy

When counting by 10s, students will notice the ones place is always 0. This pattern makes it easy to recognize multiples of 10!

Using Number Charts

Number charts up to 120 help students see patterns when skip counting. By highlighting every tenth number, the multiples of 10 stand out clearly in vertical and horizontal patterns.

Chart Activities:
  • Highlight 0, 10, 20, 30, and so on to make the multiples of 10 easy to see.
  • Notice that all highlighted numbers end with 0.
  • Compare multiples of 10 with multiples of 5 to see how patterns overlap and connect.
Instructional Focus

Use the chart to emphasize that multiples of 10 appear in regular intervals. This builds confidence in predicting the next numbers in the sequence.

Connecting Skip Counting to Real Life

Skip counting by 10s is useful in many daily situations. It helps with understanding money, measuring time, and counting objects grouped in tens.

Real-Life Examples:
  • Counting dimes: 10, 20, 30, 40 …
  • Counting minutes on a clock: 10, 20, 30 …
  • Counting fingers in two hands (10 at a time): 10, 20, 30 …
Visual Strategy

Use real objects like coins, clocks, or bundles of sticks to reinforce the skip counting sequence. Connecting numbers to everyday items makes learning meaningful.
