3. DETAILED LESSON STRUCTURE

Introduction (15 minutes)

  • Warm-up Activity:

Begin with the energetic “Counting Safari” song, where learners march around the classroom while counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s. “Let’s go on a counting safari! We’ll count the animals we see. First, we see 1 elephant, 2 elephants, 3 elephants… Now we see groups of zebras: 2, 4, 6, 8, 10!” This physical movement activates prior knowledge while introducing the lesson focus.

  • Prior Knowledge Activation:

“Yesterday we practiced counting to 100. Today we’re going to be counting detectives and discover amazing patterns when we count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s. Who can show me how to count by 2s to 20?” Allow several learners to demonstrate, celebrating their success and gently correcting misconceptions.

  • Lesson Introduction:

“Friends, today we are going to become number pattern experts! We will learn to count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s like professional mathematicians. Just like the beautiful patterns we see in Ndebele art or the regular spacing of mielie plants in a field, numbers also make wonderful patterns when we count in different ways.”

  • Learning Objectives Sharing:

“By the end of our lesson, you will be able to count like counting champions! You’ll count forwards and backwards up to 150 in many different ways – by 1s like counting your fingers, by 2s like counting your shoes, by 5s like counting your rand coins, and by 10s like counting your toes twice!”

Development (45 minutes)

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

Learners work in groups of four with counting bears and ten frames. “Let’s explore counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s using our counting bears. First, each group will make a line of 20 bears counting by 1s: 1, 2, 3, 4… up to 20. Now, let’s group them by 2s. Put 2 bears together, then 2 more, then 2 more. Count your groups: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20!”

Teacher moves between groups asking: “What do you notice about counting by 2s? Which numbers do we say? Which numbers do we skip?” Learners physically manipulate the bears to create groups of 3s, 4s, 5s, and 10s, discovering that skip counting means jumping over certain numbers in a predictable pattern.

“Now let’s try counting backwards! Start with 20 bears and remove them in groups of 2s: 20, 18, 16, 14… What’s happening to our number? Yes, it’s getting smaller each time we take away 2!”

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

Using the large floor number line, learners practice counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s as a whole class. “Thabo, please stand on number 0. Now hop forward counting by 2s. Where do you land? 2! Nomsa, continue from where Thabo stopped. Hop to the next number when we count by 2s. Where are you? 4! Excellent!”

Teacher demonstrates counting backwards: “Let’s start at 30 and count backwards by 3s. I’ll point to the numbers: 30, 27, 24, 21, 18, 15, 12, 9, 6, 3, 0. What pattern do you see? Yes, we subtract 3 each time!”

Learners work in pairs with desktop number lines, taking turns to count forwards and backwards in different intervals. “Partner A, count forwards from 45 by 5s until you reach 70. Partner B, check if they’re correct using the number line. Then switch roles and count backwards from 80 by 4s.”

  • *Phase 3: Independent Application (15 minutes)**

Learners receive differentiated worksheets focusing on counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s:

  • Level 1 (Support): Complete number sequences with only 1-2 missing numbers, counting by 2s, 5s, and 10s up to 50.

Example: “2, 4, 6, ___, 10, ___, 14”

  • Level 2 (Core): Complete longer sequences and identify patterns, counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s up to 100.

Example: “Count backwards by 4s: 48, 44, ___, ___, 32, ___, ___”

  • Level 3 (Extension): Create their own number patterns and solve complex sequences extending to 150.

Example: “Start at 17 and count forwards by 3s. Write the first 8 numbers in your sequence.”

Teacher circulates, providing individual support and asking probing questions: “How did you know the next number? What pattern are you following? Can you count backwards from here?”

Consolidation (15 minutes)

  • Summary Activity:

“Number Pattern Gallery Walk” – Groups create posters showing different ways to count forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s. Each poster includes visual representations, number sequences, and real-world examples. Groups rotate to view each other’s work, adding sticky note compliments and questions.

  • Reflection Questions:

“What was the most interesting pattern you discovered when counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s? Which counting pattern was easiest for you? Which was most challenging? How might you use skip counting in real life? Where do you see number patterns around our school or community?”

  • Connection to Next Lesson:

“Tomorrow we’ll use our skip counting skills to solve multiplication problems. If you can count by 3s, you can solve 4 × 3 by counting: 3, 6, 9, 12! Our counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s skills will help us become multiplication masters!”

4. ASSESSMENT STRATEGIES

  • Formative Assessment:

Continuous observation using a checklist during counting forwards/backwards 0–150 in 1s, 2s, 3s, 4s, 5s, 10s activities. Teacher notes accuracy, strategy use, and confidence levels. Quick “thumbs up/thumbs down” checks after each counting sequence to gauge understanding.

  • Summative Assessment:
