Australian Curriculum Alignment

Content Descriptor:

AC9MFN01 - Name, represent and order numbers including zero to at least 20, using physical and virtual materials and numerals.

Elaborations include:

• Recognising the order in the sequence of numbers to 20, identifying the number one less and one more than a given number.
• Using number cards, counting songs, storybooks, and rhymes to establish counting sequences.
• Using ordinal position vocabulary such as "first," "second," "last" etc.
• Selecting quantities to match numerals and counting to justify collections.
• Making connections between numerals, number names, and quantities using hands-on materials and culturally relevant games.

This lesson specifically targets these elements to build number sense foundation appropriate for Foundation year students.

Lesson Outline

1. Introduction and Warm-up (10 mins)

• Activity: Sing a counting song from 1 to 20, inviting students to join along. Use rhythm and hand gestures to support engagement and memory.
• Purpose: Establish a fun, active environment and activate prior knowledge of numbers 1–20.
• Use large print number cards (dyslexia-friendly font and size) visible to all students.

---

2. Main Activity: Number Sequence Puzzle (20 mins)

• Materials: Sets of large printed number cards from 1 to 20, in mixed order, printed with clear, large font for dyslexia friendliness.
• Activity:
• Give each student a number puzzle set (individual mixed cards).
• Ask them to work together to arrange the cards in correct ascending order from 1 to 20 on a table or floor space.
• Teacher facilitates by asking guiding questions: "What number comes after 7?" "Which number is before 12?"
• Use ordinal language: "Who is first? Who is last?"
• Differentiation:
• Support students who need extra help by using physical counters or objects to count alongside the cards.
• For students who may struggle, pair them with a peer or allow sorting into smaller groups.

3. Extension Activity: Personal Item Number Sequence (10 mins)

• Materials: Students bring 5-10 similar personal items (e.g., crayons, toy cars, blocks).
• Activity:
• Each student creates their own number sequence using their personal items placed in order from 1 up to the number they can manage (max 20).
• Students share their sequences with classmates, describing how they arranged items by number order.
• Purpose: Foster creativity and personal connection to numbers, deepening understanding by real-world application.

---

4. Reflection and Wrap-up (5 mins)

• Group discusses what they learned about numbers and sequences. Teacher reinforces the concept that numbers have a specific order.
• Recap success criteria by asking students to demonstrate ordering with a few number cards.

---

Differentiation Strategies

• Use large-print, high-contrast number cards to support students with dyslexia or visual difficulties.
• Provide physical counters or touch points to support counting for tactile learners.
• Pair students for peer support and cooperative learning.

---

Assessment Opportunities

• Observation of students’ ability to place numbers in correct order during the puzzle activity.
• Listening to student explanations during the personal item sequence activity for vocabulary and conceptual understanding.
• Use oral questioning throughout to check understanding of "before," "after," "one more," and "one less."

---

Teacher Notes

• Use culturally responsive materials and examples, such as counting local natural objects where possible.
• Relate counting to students' experiences and environment to enhance engagement.
• Maintain an encouraging atmosphere that values attempts and progress in sequence learning.

This detailed lesson plan follows the Foundation Year mathematics curriculum requirements, perfectly aligning with AC9MFN01 to teach sequencing numbers 1-20, incorporating active engagement, differentiated support, and extension to challenge advanced learners. It also offers dyslexia-friendly resources to promote accessibility for all students.
