3. DETAILED LESSON STRUCTURE

Introduction (15 minutes)

  • Warm-up Activity: Begin with the energetic “Counting Clap” song where learners clap and count in 10s from 0 to 100, then backwards. “Let’s count by 10s and clap our hands! 10, 20, 30… all the way to 100! Now backwards we go – 100, 90, 80…” This activates prior knowledge of counting forwards/backwards in 10s before extending to count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s.
  • Prior Knowledge Activation: “Yesterday we practiced counting to 100 in 10s. Today we’re going to be counting detectives! We’ll discover new patterns when we count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s. Who can show me how to count by 2s starting from 0? Let’s try: 0, 2, 4, 6, 8, 10!”
  • Lesson Introduction: “Friends, today we’re going on a number adventure! We’re going to learn how to count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s. This means we can count by jumping different amounts each time – sometimes by 2s like a bunny hop, sometimes by 5s like counting fingers, and sometimes by 10s like counting toes on both feet!”
  • Learning Objectives Sharing: “By the end of our lesson, you’ll be able to count like mathematicians! You’ll count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s and spot the special patterns that appear. You’ll also help your friends when they get stuck in a counting sequence!”

Development (45 minutes)

  • *Phase 1: Concrete Exploration (15 minutes)**

Learners work in groups of four with counting bears and ten frames. “Let’s start exploring count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s using our counting bears! Group 1, place your bears in groups of 2. Count how many bears you have by 2s: 2, 4, 6, 8, 10, 12… Group 2, make groups of 5 bears. Count by 5s: 5, 10, 15, 20, 25, 30…”

Teacher moves between groups asking: “What do you notice about the last digit when we count by 2s? What pattern do you see when counting by 5s? Can you predict the next number in your sequence?” Groups physically manipulate bears to create visual representations of skip counting patterns, building concrete understanding of count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s.

“Now let’s try counting backwards! Start with 20 bears in groups of 2. Remove one group at a time and count backwards by 2s: 20, 18, 16, 14, 12, 10, 8, 6, 4, 2, 0. What happens to our pattern when we count backwards?”

  • *Phase 2: Guided Practice (15 minutes)**

Using the large classroom number line, teacher models count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s while learners follow along. “Watch as I hop along our number line counting by 3s. I’ll start at 0 and jump 3 spaces each time: 0, 3, 6, 9, 12, 15, 18, 21… Who can tell me where I’ll land next?”

Learners take turns being “number hoppers” on a floor number line, physically jumping to demonstrate count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s. “Sipho, show us counting by 4s starting from 0. Remember to jump 4 spaces each time! Class, let’s count together: 4, 8, 12, 16, 20…”

Teacher provides sentence frames: “When I count by ___s, I start at ___ and the pattern is ___.” Learners complete these statements for different skip counting sequences, reinforcing their understanding of count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s.

  • *Phase 3: Independent Application (15 minutes)**
  • Level 1 (Support needed): Learners complete number sequences with visual support from hundred squares. They fill in missing numbers when counting by 2s and 5s up to 50, using colored pencils to highlight patterns.
  • Level 2 (Working independently): Learners complete worksheets showing various skip counting sequences up to 100, identifying patterns and filling in missing numbers for count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s.
  • Level 3 (Extension): Advanced learners create their own skip counting puzzles, write number sequences up to 150, and challenge classmates to identify the counting pattern and continue the sequence.

All learners record their work in exercise books, drawing pictures to represent their skip counting patterns and writing number sequences for count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s.

Consolidation (15 minutes)

  • Summary Activity: “Number Pattern Gallery Walk” where groups display their skip counting work around the classroom. Learners rotate to view different examples of count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s, discussing patterns they observe and asking questions about different counting sequences.
  • Reflection Questions:
  • “Which skip counting pattern was easiest for you when learning count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s? Why?”
  • “What patterns did you notice when counting by 5s compared to counting by 10s?”
  • “How can knowing these patterns help you in everyday life?”
  • “What was challenging about counting backwards in different intervals?”
  • Connection to Next Lesson: “Tomorrow we’ll use our knowledge of count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s to solve word problems. We’ll count groups of objects and find totals using our skip counting skills!”

4. ASSESSMENT STRATEGIES
