Shapes All Around

Overview

In this 30-minute session, preschool students will explore basic two-dimensional shapes—circle, square, and triangle—through an interactive, playful Shape Scavenger Hunt in the classroom. The lesson immerses children in hands-on learning, encouraging them to identify and describe shapes they encounter daily while developing language and cognitive skills aligned with the New Zealand Curriculum Refresh (Te Mātaiaho Mathematics and Statistics, Phase 1).

Curriculum Alignment

New Zealand Curriculum Refresh - Mathematics and Statistics, Phase 1 (Preschool):

• Geometry strand:

  • Learning Areas: Identify, sort by one feature, and describe familiar 2D shapes including triangles, circles, and squares.
  • Use everyday and mathematical language (including te reo Māori) to describe shapes, e.g., corners, sides, and names such as tapatoru (triangle), tapawhā rite (square), porowhita (circle).
  • Investigate 2D shapes in the environment (Te Mātaiaho 0–8, first year learning) .

• Key Competencies:

  • Thinking: Observing, sorting, making connections.
  • Using language, symbols and texts: Using mathematical words and te reo Māori vocabulary to talk about shapes.
  • Participation and contribution: Cooperating in a small group activity, sharing observations.

Learning Objectives

By the end of this lesson, students will:

• Recognise and name the basic shapes: circle, square, and triangle.
• Identify these shapes in the classroom environment.
• Use simple mathematical language (English and te reo Māori) to describe shape attributes (e.g., corners, sides).
• Demonstrate an understanding of shapes through a fun, collaborative scavenger hunt activity.

Resources

• Shape flashcards (circle, square, triangle) with English and te reo Māori names.
• A small basket or bag for collecting shape cards or tokens.
• Classroom objects featuring the basic shapes (e.g., clock = circle, book = square, toy block = triangle).
• Printed checklist with pictures and words of the three shapes.
• Large floor mat or carpet area for group discussion and gathering.

Lesson Breakdown

1. Welcome and Introduction (5 minutes)

• Begin with a brief warm-up song or chant about shapes, including their names in English and te reo Māori (e.g., "Tapawhā rite, tapatoru, porowhita!").
• Show each shape flashcard one-by-one, say the name slowly, and ask the children to repeat.
• Describe key attributes: circle has no corners, square has four equal sides and corners, triangle has three sides and corners. Use fingers or body to demonstrate.
• Emphasise the use of shape names in both languages to build vocabulary.

2. Guided Shape Scavenger Hunt (15 minutes)

• Explain the scavenger hunt rules: They will look around the classroom together for objects matching each shape on the checklist.
• Model how to find and describe an object, e.g., "This clock is a circle / He porowhita tēnei karaka."
• In small groups (4 students), guide the children around the classroom, pausing at objects and encouraging them to identify the shape and use the vocabulary.
• Each time they find a shape, tick it off on the checklist and collect a corresponding shape token or flashcard.
• Help children with pronunciation and attribute identification, reinforce shape language continuously.

3. Group Reflection and Sharing (7 minutes)

• Gather back on the mat. Invite each child to share one object they found and describe its shape in simple terms.
• Use open-ended prompts such as: "Who found a square? What is it? How do you know it’s a square?"
• Celebrate their efforts with positive feedback and reinforce key vocabulary.
• Recap in English and te reo Māori the shapes discovered.

4. Closing Activity and Wrap-up (3 minutes)

• Finish with a quick “Shape Freeze Dance”: play music and when it stops, call out a shape name and the children pose like that shape (e.g., make a circle shape with arms).
• Encourage fun and movement while reinforcing shape recognition.
• Give each child a simple sticker or stamp as a reward for participation.

Assessment and Reflection

• Formative assessment:

  • Observe children's ability to recognise and name shapes during the scavenger hunt.
  • Listen for correct use of shape vocabulary in English and te reo Māori.
  • Note participation and confidence in describing shapes.

• Next steps:

  • Plan subsequent sessions to explore composing and decomposing shapes using materials such as pattern blocks or playdough, as suggested in the curriculum’s teaching considerations for early years .
  • Encourage integration with language development by expanding descriptive adjectives (big, small, colour) and patterns to follow later lessons in the unit.

Reflection for Teacher Use

• Did children remain engaged and interested during the hunt?
• Were the shapes sufficiently represented in the classroom environment? Adjust future hunts if necessary.
• How effectively did children grasp dual-language shape vocabulary? Consider more te reo Māori immersion if helpful.
• How was group interaction? Adapt the group size or guidance level accordingly.
