Curriculum Connections: British Columbia (BC) Early Years Mathematics Curriculum Framework

Big Ideas:

• Numbers represent quantities that can be counted, compared, and ordered.
• Number sense develops through working with numbers in meaningful contexts.

Curricular Competencies:

• Estimate, count, and represent quantities.
• Develop and apply counting strategies to determine the number of items in a collection.

Content:

• Count to 20, demonstrating one-to-one correspondence and stable order.
• Use counting principles: one-to-one correspondence, stable order, cardinality, order irrelevance, and abstraction.

I Can Statement:

• I can count collections up to 20 accurately, using counting principles.

---

Learning Objectives

By the end of this lesson, students will be able to:

• Demonstrate understanding of counting principles (one-to-one correspondence, stable order, cardinality).
• Count objects in collections up to 20 with accuracy.
• Show confidence counting smaller sets (1–10) to build foundational skills.
• Use number words and counting techniques demonstrated in visual aids and videos.

---

Success Criteria

Students will demonstrate success when they can:

• Count objects out loud confidently and accurately up to 20.
• Point to each object as they count to show understanding of one-to-one correspondence.
• Explain how many objects are in a collection and show that the last number counted represents the total (cardinality).
• Use different strategies if stuck, such as grouping or touch counting.

---

Materials

• Physical counters (e.g., cubes, bears, buttons) in sets of 5, 10, and 20.
• Smaller sets of objects (up to 10) for struggling learners.
• Whiteboard and markers.
• Projector/screen to show counting videos with visual aids.
• Counting mats or trays.
• Student counting record sheets (with spaces to draw and write numbers).
• Dyslexia-friendly printouts with minimal text, clear font, and visual cues.

Lesson Structure

1. Engage (10 minutes)

• Introduce the lesson with the goal: “I can count collections to 20.”
• Display 10 objects in a collection and ask: “How many do you see?”
• Watch a short video that demonstrates counting principles: pointing to each object as number words are spoken. The video uses clear visuals and slow pacing to support all learners, including those with dyslexia.
• Discuss the video: What do we notice about how the objects were counted? (One-to-one correspondence, stable order of number words, last number says how many.)

2. Mini-Lesson: Counting Principles (10 minutes)

• Teacher-led demonstration counting a collection of 15 objects on the counting mat.
• Highlight and explicitly name the counting principles:
  • One-to-one correspondence: each object matched with one number.
  • Stable order: counting in the same order each time.
  • Cardinality: the last number counted is the total number.
• Show common errors (e.g., skipping objects or numbers) and discuss why they cause mistakes.
• Use a dyslexia-friendly visual aid chart with these principles and icons to reinforce understanding.

3. Guided Practice (15 minutes)

• Divide students into pairs.
• Each pair receives a collection of 10 objects or fewer for students needing more support. Others receive collections of up to 20.
• Using counting mats and counters, students take turns counting the objects aloud to each other.
• Teacher circulates to provide support, praising correct use of counting principles.
• Encourage students to self-check by asking: “Did I say one number for each object?” and “Did I say the last number as the total?”

4. Independent Learning Centres (15 minutes)

• Students move to different counting centres across the classroom:
  • Centre 1: Counting real objects (buttons, cubes) into sets of 5 and 10 with guided record sheets.
  • Centre 2: Counting collections shown in picture form on cards up to 20, with verbal prompts.
  • Centre 3 (Extension): Students count mixed objects of different sizes and colours, practicing order irrelevance (counting in any order).
• Students complete a short worksheet recording their total count and drawing the collection. Dyslexic students can use picture-based recording sheets with number symbols.

5. Closure and Reflection (10 minutes)

• Regroup for a class discussion:
  • Ask several students to share how many objects they counted and how they knew their count was right.
  • Revisit the “I can…” statement and success criteria.
  • Reinforce the importance of counting carefully and confidently.
• Show a brief video summarizing counting skills with animation and repeat key counting principles for reinforcement.
• Set a home connection task, where students can count objects at home (e.g., toys or snacks) and bring a picture or drawing to share next lesson.

Differentiation Strategies

Learner Type	Strategy
Struggling learners	Use smaller collections (1-10), visual aids, verbal prompting, and counting alongside them.
English Language Learners	Use visual counting videos with clear, slow narration; gesture and modelling; label objects with simple words.
Advanced learners	Provide mixed object collections and challenge with counting in different orders; introduce skip counting foundations (e.g., 2s, 5s).
Dyslexic learners	Dyslexia-friendly resources, use of pictures rather than text, multi-sensory counting activities, paired work with strong peer models.

Assessment

Formative Assessment:

• Teacher observations during guided practice and independent centres.
• Use anecdotal notes to track mastery of counting principles.
• Check student recording sheets for accurate counts and understanding.
• Ask oral questions using success criteria to gauge comprehension.

Summative Assessment:

• End-of-unit assessment task (later in the unit) where students count a collection and explain their counting process, referencing counting principles.

---

Extension Activities

• Use number stories and scenarios to create and count collections at home or in the classroom.
• Introduce simple addition using two collections counted separately, then combined.
• Explore non-standard units of measurement (e.g., count objects by grouping two at a time).
• Use interactive digital counting games that reinforce counting principles visually.

---

Teacher Reflection:

• How did students respond to counting principles?
• Which students needed extra support and which thrived?
• Were the videos and visual aids effective for diverse learners?
• How to adjust future lessons based on today’s engagement and assessment?
