Topic: Skip Counting
Sub-topic: Skip Counting by 2s, 5s, and 10s up to 100
Learning Objectives
By the end of the lesson, students should be able to:
Count forward and backward by 2s, 5s, and 10s up to 100
Use number lines, counters, and patterns for skip counting
Apply skip counting to solve simple problems like counting groups of objects
Previous Knowledge
Students already know how to count numbers up to 100 in ones.
Instructional Materials
Mathematics textbook for Grade 1, counters, number charts, coins, sticks.
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
The teacher asks students to clap while counting in twos: 2, 4, 6, 8, 10. Then they try fives and tens.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
The teacher explains that skip counting means counting by jumping over numbers in equal steps.
Examples:
By 2s → 2, 4, 6, 8, 10… 100
By 5s → 5, 10, 15, 20… 100
By 10s → 10, 20, 30, 40… 100
The teacher demonstrates with counters: group counters into 5s and count them quickly. The teacher also uses money examples, showing that two L$5 notes make L$10, and continuing.
Learners’ Activities (Expanded):
Students use number lines to practice skip counting.
Students count groups of 2s, 5s, and 10s using counters.
Students apply skip counting to solve simple problems, such as finding how many tens make 100.
Assessment Checks:
Count by 2s to 20.
Count by 5s to 40.
Count by 10s backward from 100 to 0.
Notes (Expanded & Detailed):
Skip counting helps in faster counting and lays a foundation for multiplication. It is used in real life when counting money, groups of objects, or repeated patterns.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Skip counting means counting in equal steps. It can be done by 2s, 5s, or 10s. It is useful in solving problems faster.
Evaluation Method (Expanded):
Exit slip/quiz: Write the next three numbers in the sequence 10, 20, 30, __, __, __. Count by 2s from 12 to 20. Count by 5s from 25 to 40.
Teacher will collect slips and provide oral feedback.
Assignment (Expanded):
Write the sequence of numbers from 0 to 100 counting by 5s in your notebook.
Follow-up Activity:
Students practice skip counting using household items like spoons, pencils, or money.
Differentiation / Inclusive Strategies
Provide visual aids like number lines for weaker learners. Advanced learners practice skip counting beyond 100.
