3. DETAILED LESSON STRUCTURE

Introduction (15 minutes)

  • Warm-up Activity: Begin with the energetic “Counting Clap” song where learners clap and count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. Start with familiar counting in 1s from 0-20, then introduce skip counting in 2s: “2, 4, 6, 8, who do we appreciate? Numbers, numbers, hooray!” 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 number detectives and discover exciting patterns when we count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. Who can show me how to count by 1s from 10 to 20?” Allow several learners to demonstrate, then ask: “What do you notice about the pattern when we count by 1s?”
  • Lesson Introduction: “Class, today we’re going on a number adventure! We’re going to learn how to count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. This means we can count by jumping like a kangaroo – sometimes taking small jumps of 1, sometimes bigger jumps of 2, 3, 4, 5, or even giant jumps of 10! By the end of our lesson, you’ll be counting champions who can count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s like mathematical superheroes!”
  • Learning Objectives Sharing: “Today you will learn to count forwards and backwards like counting experts, discover beautiful number patterns, and become confident with numbers up to 170. You’ll be able to count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s and help your family count things at home!”

Development (45 minutes)

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

Begin with hands-on exploration using counting bears. Distribute 20 counting bears to each pair of learners. “Let’s start our journey to count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s by using our counting bears. First, let’s count by 1s – place one bear at a time and count: 1, 2, 3, 4, 5… up to 20.”

Next, introduce skip counting with concrete materials: “Now we’ll count by 2s. Put your bears in groups of 2. Count each group: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. This is counting forwards in 2s!” Demonstrate counting backwards: “Now let’s count backwards in 2s: 20, 18, 16, 14, 12, 10, 8, 6, 4, 2, 0.”

Continue with groups of 5: “Make groups of 5 bears. Count by 5s: 5, 10, 15, 20. Now backwards: 20, 15, 10, 5, 0.” Use ten frames to reinforce counting by 10s up to 100, then extend to 170 using the number chart.

Teacher questions: “What do you notice about the last digit when we count by 2s? What pattern do you see when counting by 5s? How is counting by 10s different from counting by 1s?”

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

Move to the large floor number line for kinesthetic learning. “Now we’ll practice counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s by moving on our number line. Sarah, please step on every number as we count by 1s from 0 to 20.”

Demonstrate skip counting patterns: “Tom, jump on every second number as we count by 2s: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. Now let’s count backwards – jump backwards: 20, 18, 16, 14, 12, 10, 8, 6, 4, 2, 0.”

Practice counting by 3s using the number chart: “Let’s count by 3s together: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30. Notice the pattern! Now backwards: 30, 27, 24, 21, 18, 15, 12, 9, 6, 3, 0.”

Extend to larger numbers using the wall chart: “Look at our big number chart. Let’s count by 10s all the way to 170: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170. Now backwards from 170!”

Group activity: Divide class into five groups, each assigned a different skip counting pattern (1s, 2s, 3s, 5s, 10s). Groups take turns demonstrating their pattern while others identify the counting rule.

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

Provide differentiated worksheets focusing on counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s:

  • Level 1 (Support): Complete number sequences with visual aids:
  • Count by 2s: 2, 4, __, 8, __, 12
  • Count by 5s: 5, __, 15, __, 25
  • Count backwards by 10s: 50, 40, __, 20, __
  • Level 2 (Core): Fill in missing numbers and identify patterns:
  • Count by 3s: 0, 3, 6, __, 12, __, 18, __, 24
  • Count backwards by 4s: 40, 36, __, 28, __, 20
  • Extend patterns to 100
  • Level 3 (Extension): Create own patterns and solve problems:
  • Continue counting by 4s from 80 to 120
  • Count backwards by 3s from 150 to 120
  • Find the missing numbers in mixed patterns

Learners work independently while teacher circulates, providing support and observing progress in counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s.

Consolidation (15 minutes)

  • Summary Activity: Conduct a “Number Pattern Gallery Walk” where learners post their completed sequences around the classroom. Each learner visits three different patterns and checks the accuracy of counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s.
  • Reflection Questions:
  • “Which counting pattern was easiest for you when counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s? Why?”
  • “What patterns did you notice in the ones place when skip counting?”
  • “How can counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s help you in real life?”
  • “What was challenging about counting backwards compared to forwards?”
  • Connection to Next Lesson: “Tomorrow we’ll use our skills in counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s to solve word problems about groups of objects. We’ll count toys in a toy shop and money in a piggy bank!”

4. ASSESSMENT STRATEGIES

  • Formative Assessment: Continuous observation during all activities focusing on accuracy and confidence when learners count forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s. Use thumbs up/down for quick comprehension checks, listen to partner conversations, and note common misconceptions.
  • Summative Assessment: Individual assessment where each learner demonstrates counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s using number cards. Assess completed worksheets for pattern recognition and sequence completion accuracy.
  • Success Criteria:
  • Accurately count forwards by 1s, 2s, 5s, 10s from 0 to at least 50
  • Count backwards by 1s, 2s, 5s, 10s from 50 to 0
  • Identify and continue number patterns
  • Recognize counting errors and self-correct
  • Assessment Tools: Checklist including: counts accurately in each interval, identifies patterns, counts forwards confidently, counts backwards with support, extends patterns beyond given examples.
  • Recording Methods: Individual progress sheets tracking mastery of each counting interval, anecdotal notes about problem-solving strategies, photographic evidence of concrete work.

5. DIFFERENTIATION STRATEGIES

  • Support for Struggling Learners: Provide number charts for reference, use smaller number ranges (0-50), offer additional concrete manipulatives, pair with confident counting partners, focus on 1s, 2s, 5s, and 10s initially before introducing 3s and 4s.
  • Extension for Advanced Learners: Challenge with counting by 6s, 7s, 8s, 9s, extend range to 200, create word problems involving skip counting, explore patterns in hundreds chart, investigate what happens when counting by different intervals.
  • Inclusive Strategies: Use visual, auditory, and kinesthetic approaches simultaneously, provide large-print number charts, use high-contrast materials, offer alternative recording methods (verbal responses, pointing, matching).
  • Language Support: Display vocabulary with visual representations, encourage home language discussions about patterns, use gestures and actions to support counting, provide sentence frames: “When I count by __, the pattern is __.”
  • Learning Style Accommodations:
  • Visual: colorful charts, pattern highlighting, graphic organizers
  • Auditory: counting songs, rhythm patterns, verbal explanations
  • Kinesthetic: movement activities, manipulatives, floor number line

6. EXTENSION AND HOMEWORK

  • Optional Extension Activities: “Number Detective” homework where learners find examples of skip counting at home (pairs of shoes for counting by 2s, fingers for counting by 5s, egg cartons for counting by 10s). Create a family counting game using household objects.
  • Family Involvement: Send home a simple guide showing parents how to practice counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s during daily activities like setting the table, counting stairs, or organizing toys.
  • Cross-curricular Connections: Link to Life Skills by counting healthy foods in groups, connect to English by reading counting books, integrate with Physical Education through counting exercises and movements, relate to Social Sciences by counting community helpers or transport vehicles.

This comprehensive lesson plan ensures learners develop strong foundational skills in counting forwards/backwards 0–170 in 1s, 2s, 3s, 4s, 5s, 10s while engaging multiple learning styles and providing appropriate support for diverse learners in the South African Foundation Phase context.
