Lesson Plan: Counting & Number Patterns

1. LESSON INFORMATION

  • Subject & Grade: Mathematics – Grade 2
  • Topic: Count forwards/backwards 0–180 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 through systematic counting patterns, which forms the foundation for multiplication tables and number relationships. It meets the CAPS expectation that Grade 2 learners should demonstrate fluency in counting forwards and backwards within the range 0-180 using various intervals.
  • Learning Objectives:
  • Knowledge: Learners will know the sequence of numbers when counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s and understand that each counting pattern follows a predictable rule
  • Skills: Learners will be able to accurately count forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s, identify missing numbers in counting sequences, and continue given patterns independently
  • Values: Learners will develop confidence in mathematical thinking, persistence when working with number patterns, and appreciation for the logical structure of our number system
  • Key Vocabulary:
  • Pattern (patroon)
  • Forwards (vorentoe)
  • Backwards (agtertoe)
  • Sequence (volgorde)
  • Skip counting (tel met tussenposes)
  • Prerequisites: Learners should be able to count forwards and backwards 0-100 in 1s, recognize number symbols 0-180, understand the concepts of “more than” and “less than,” and have basic experience with counting in 2s, 5s, and 10s within smaller ranges.

3. DETAILED LESSON STRUCTURE

Introduction (15 minutes)

  • Warm-up Activity: Begin with the energetic South African counting song “Count with the Big Five.” Display pictures of elephants, lions, leopards, rhinos, and buffalo while learners count in 5s: “5 elephants, 10 lions, 15 leopards, 20 rhinos, 25 buffalo!” Continue this pattern up to 50, with learners clapping on each multiple of 5.
  • Prior Knowledge Activation: “Yesterday we practiced counting in 10s up to 100. Let’s see if you remember! I’ll start: 10, 20, 30…” Allow learners to continue the sequence. Then challenge them: “Now let’s count backwards from 50: 50, 40, 30…” This activates their understanding of counting patterns and directional counting.
  • Lesson Introduction: “Today we’re going on a mathematical safari! We’ll explore how to count forwards and backwards from 0 to 180 using different step sizes – sometimes we’ll take baby steps counting by 1s, sometimes we’ll hop like springbok counting by 2s, march like elephants counting by 5s, or leap like impala counting by 10s. By the end of our safari, you’ll be expert counters who can count forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s!”
  • Learning Objectives Sharing: “Today you will learn to count forwards and backwards like mathematical explorers! You’ll discover the secret patterns when we count forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s. You’ll become pattern detectives who can spot missing numbers and continue counting sequences all the way to 180!”

Development (45 minutes)

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

Begin with hands-on exploration using counting bears arranged in groups. Give each group of four learners 50 counting bears and egg cartons. “Let’s start our safari by counting forwards in 2s like hopping springbok! Place 2 bears in each section of your egg carton. Now let’s count together: 2, 4, 6, 8, 10…” Continue until reaching 24 bears (12 groups of 2).

Next, demonstrate counting backwards: “Now our springbok are hopping home! Let’s count backwards in 2s: 24, 22, 20, 18…” Guide learners to remove 2 bears at a time while counting backwards.

Repeat this concrete exploration with groups of 5 using South African 5-cent coins: “Now we’re counting elephant steps in 5s! Each elephant step is worth 5 cents. Let’s count forwards: 5 cents, 10 cents, 15 cents…” Continue to 50 cents, then count backwards.

Teacher circulates asking: “What do you notice about counting in 2s? What pattern do you see? How is counting backwards different from counting forwards?” This concrete manipulation helps learners physically experience the concept of counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s.

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

Move to semi-concrete representation using the large classroom number line. “Now let’s use our number line to practice counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s!”

Start with counting in 3s: “Let’s count like three-legged pot (potjiekos) – every third number! Start at 0, jump to 3, then 6, then 9…” Use colored markers to highlight multiples of 3 on the number line up to 60. Then practice counting backwards: “60, 57, 54, 51…”

Continue with counting in 4s: “Now we’re counting like the legs of our African animals – 4 legs each! 0, 4, 8, 12, 16, 20…” Extend the pattern to 80, then practice backwards counting.

For counting in 10s, use the hundred chart: “Let’s count like we’re collecting 10-cent coins! 0, 10, 20, 30…” Continue all the way to 180, emphasizing the pattern. “Notice how we always land on numbers ending in 0!”

Engage learners with questions: “If we’re at 45 and counting backwards in 5s, what comes next? If we start at 72 and count forwards in 4s, where will we be after 3 jumps?” This guided practice reinforces the skill of counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s.

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

Provide differentiated worksheets for independent practice of counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s:

  • Level 1 (Support): Number sequences with most numbers filled in, learners complete missing numbers:
  • “Count in 2s: 14, 16, __, 20, __, 24”
  • “Count backwards in 5s: 35, 30, __, 20, __, 10”
  • Level 2 (Core): Longer sequences with several missing numbers:
  • “Count in 3s: 21, __, __, 30, __, 36, __”
  • “Count backwards in 4s: 48, __, 40, __, __, 28”
  • Level 3 (Extension): Create their own counting patterns and solve word problems:
  • “Start at 67 and count backwards in 3s. Write the first 8 numbers.”
  • “Nomsa is collecting stickers in groups of 4. She has 76 stickers. How many groups is that?”

Learners work individually while teacher provides targeted support. Those who finish early can use tablets with counting apps or create their own number pattern puzzles for classmates.

Consolidation (15 minutes)

  • Summary Activity: Conduct a “Counting Safari Showcase” where learners demonstrate their mastery of counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s. Divide the class into six groups, each assigned a different counting pattern. Groups take turns performing their counting pattern using actions:
  • 1s group: March steadily counting 45-55
  • 2s group: Hop like springbok counting 30-50
  • 3s group: Clap rhythm counting backwards from 60-30
  • 4s group: Step in squares counting 40-80
  • 5s group: High-five counting backwards from 100-50
  • 10s group: Jump counting 80-180
  • Reflection Questions:

“Which counting pattern was easiest for you when counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s? Why do you think that is? What patterns did you notice? How might counting in different steps help us in real life? When might we count in 5s or 10s outside of school?”

  • Connection to Next Lesson: “Tomorrow we’ll use our expert counting skills to solve problems about grouping and sharing. We’ll discover how counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s helps us understand multiplication and division!”

4. ASSESSMENT STRATEGIES

  • Formative Assessment: Continuous observation during all activities focusing on accuracy, confidence, and understanding when learners count forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s. Use questioning techniques: “What comes next? How do you know? What pattern do you see?” Document observations on individual tracking sheets.
  • Summative Assessment: Individual assessment where each learner demonstrates counting forwards/backwards 0–180 in 1s, 2s, 3s, 4s, 5s, 10s through:
