Lesson Plan: Counting & Number Patterns

1. LESSON INFORMATION

  • Subject & Grade: Mathematics – Grade 2
  • Topic: Count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s
  • Duration: 60 minutes
  • CAPS Alignment: This lesson directly aligns with CAPS Mathematics Grade 2 Term 3 requirements for Number, Operations and Relationships, specifically addressing the counting and number patterns strand. The lesson supports the development of number sense by extending learners’ ability to count forwards and backwards 0–170 in various intervals (1s, 2s, 3s, 4s, 5s, 10s), building foundational skills for multiplication, division, and pattern recognition as outlined in the CAPS progression.
  • Learning Objectives:
  • Knowledge: Learners will know the sequence of numbers from 0–170 when counting forwards and backwards in intervals of 1s, 2s, 3s, 4s, 5s, and 10s, understanding that each interval creates a predictable pattern.
  • Skills: Learners will be able to accurately count forwards and backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s, identify missing numbers in these sequences, and recognize patterns within each counting interval.
  • Values: Learners will develop confidence in mathematical thinking, persistence when working with number patterns, and appreciation for the logical structure of our number system through exploring count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s.
  • Key Vocabulary:
  • Forwards (vooruit) – counting in ascending order
  • Backwards (agteruit) – counting in descending order
  • Pattern (patroon) – a repeated sequence in numbers
  • Interval (tussenpoos) – the space between numbers in a sequence
  • Sequence (volgorde) – numbers arranged in a particular order
  • Prerequisites: Learners should be able to count forwards and backwards 0–100 in 1s and 10s, recognize number symbols 0–170, understand concepts of “more than” and “less than,” and have basic experience with skip counting in 2s and 5s to 50.

3. DETAILED LESSON STRUCTURE

Introduction (15 minutes)

  • Warm-up Activity: Begin with the energetic “Counting Safari” song where learners march in place while counting in 10s: “10 elephants stomping through the bush, 20 elephants stomping through the bush…” up to 100, then backwards. This connects to South African wildlife while reinforcing the concept of count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s.
  • Prior Knowledge Activation: “Yesterday we practiced counting to 100 in different ways. Show me with your fingers how we count in 5s – 5, 10, 15, 20! Today we’re going to become number pattern detectives and explore how to count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. Who can tell me what number comes after 100 when we count in 1s?”
  • Lesson Introduction: “Friends, today we are going on an exciting mathematical journey where we will learn to count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. This means we can count like taking tiny steps of 1, or bigger jumps of 2, 3, 4, 5, or giant leaps of 10! We’ll discover the special patterns hidden in numbers up to 170.”
  • Learning Objectives Sharing: “By the end of our lesson, you will be able to count forwards and backwards like mathematical athletes – sometimes taking small steps of 1, sometimes hopping in 2s like a rabbit, jumping in 5s like a frog, or leaping in 10s like a springbok! You’ll also spot the secret patterns that make counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s easier and more fun.”

Development (45 minutes)

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

Learners work in pairs with counting beans and ten-frames to physically explore count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. Start with counting in 10s using ten-frames: “Place one full ten-frame, count ’10.’ Add another, count ’20.’ Continue until you reach 100, then keep going – 110, 120, 130, 140, 150, 160, 170.”

Teacher moves between pairs asking: “What do you notice about the pattern when we count forwards in 10s? Now let’s count backwards from 170 – take away one ten-frame at a time. What happens to our numbers?”

Next, explore counting in 5s using beans arranged in groups of 5: “Make groups of 5 beans. Count each group: 5, 10, 15, 20… How far can you go toward 170?” Learners physically manipulate the beans while counting, reinforcing the concrete understanding of count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s.

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

Using the large classroom number chart, demonstrate counting patterns together. “Let’s count forwards in 2s starting from 0. I’ll point, you count: 0, 2, 4, 6, 8, 10…” Continue to 50, then extend: “What comes after 50 when counting in 2s? Yes, 52, 54, 56…” Reach toward 170.

Practice backwards counting: “Now we’ll count backwards in 5s from 100. Ready? 100, 95, 90, 85…” Model the thinking: “When I count backwards in 5s, I subtract 5 each time. What number comes before 85 in our pattern?”

Introduce counting in 3s and 4s using visual patterns: “Look at this pattern of triangles – each triangle has 3 sides. Count the sides: 3, 6, 9, 12…” For 4s, use squares: “Each square has 4 sides: 4, 8, 12, 16…” This reinforces count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s through visual-spatial learning.

  • *Phase 3: Independent Application (15 minutes)**
  • For developing learners: Provide number line strips marked 0–100 with some numbers missing. Learners fill in missing numbers when counting in 10s and 5s, then extend patterns toward 170.
  • For competent learners: Complete worksheets showing partial sequences for count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s with various starting points. For example: “Continue this pattern: 45, 50, 55, 60, __, __, __” or “Count backwards: 84, 80, 76, 72, __, __, __”
  • For advanced learners: Create their own counting patterns, identify which interval is being used in given sequences, and solve number puzzles involving count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s.

Consolidation (15 minutes)

  • Summary Activity: “Number Pattern Gallery Walk” – learners rotate through stations displaying different counting sequences for count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. At each station, they identify the pattern, fill in missing numbers, and explain their thinking to a partner.
  • Reflection Questions: “What was the easiest interval for you when learning to count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s? Which was most challenging? How do patterns help us count more quickly? When might we use skip counting in real life?”
  • Connection to Next Lesson: “Tomorrow we’ll use our skills in count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s to solve problems about grouping objects and sharing equally. We’ll discover how counting patterns connect to multiplication!”

4. ASSESSMENT STRATEGIES

  • Formative Assessment: Continuous observation using checklist during count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s activities. Note accuracy, confidence, pattern recognition, and ability to self-correct. Listen for mathematical language use and peer explanations.
  • Summative Assessment: Individual oral assessment where each learner demonstrates count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s starting from different points. Written assessment includes completing number sequences, identifying patterns, and solving missing number problems.
