Shape Hunt Game

Overview

In this fifth lesson of Exploring 2D Shapes Fun, students use familiar 2D shapes to investigate objects in the classroom and school environment. They apply shape names and visual features, explain their choices, and record findings through an active, collaborative shape hunt.

Learning intentions

Students will:

• recognise and name circles, triangles, squares and rectangles in everyday objects
• describe familiar shapes using features such as sides, corners and curved edges
• sort and record objects according to their shape
• explain why an object matches a particular shape

Success criteria

• I can name a circle, triangle, square and rectangle.
• I can find an object that matches a given shape.
• I can describe what I notice about a shape.
• I can explain why I sorted an object into a shape group.

Curriculum links

• Foundation Mathematics: sort, name and create familiar shapes.
• Foundation Mathematics: recognise and describe familiar shapes within objects in the environment, giving reasons.
• Students develop mathematical language, reasoning, collaboration and observation skills.

Lesson structure (45 minutes)

1. 0–5 min · Welcome and hook. Teacher displays the opening shape mystery showing a familiar object partly hidden and asks, “What shapes might be hiding in our classroom?” Students make a quiet guess, then share the shape they noticed and explain what helped them decide.

2. 5–12 min · Revise and model. Teacher uses the shape review slides to revisit circle, triangle, square and rectangle, modelling how to look for straight or curved edges, sides and corners. Students make the shapes in the air, trace them with a finger, and practise saying a sentence such as, “I think this is a rectangle because it has four straight sides.”

3. 12–16 min · Explain the hunt. Teacher shows the hunt instructions and models finding one safe classroom object, naming its shape and recording it on the shape hunt recording sheet. Establish boundaries: students walk, stay with their partner, do not touch unsafe or personal items, and ask before moving anything. Students repeat the safety rule and practise recording one example together.

4. 16–29 min · Partner shape hunt. Teacher places students in 12 pairs and one trio, gives each group a recording sheet and pencil, and circulates with the prompt, “What shape do you see? What is your reason?” Students search the approved classroom area for objects that look like circles, triangles, squares or rectangles, recording or drawing the object in the matching section. They may find more than one object for each shape.

5. 29–37 min · Sort, compare and discuss. Teacher signals students to return and uses the share-and-sort slides to display the four shape groups. Students share one discovery with their partner, then contribute examples to a class sort. Discuss objects that may be close to, but not exact examples of, a shape; for instance, a book may look like a rectangle even if its corners are rounded.

6. 37–45 min · Plenary and assessment. Teacher displays the final challenge slides and asks, “Which shape was easiest to find? Which was hardest? Why?” Students complete the final prompt on the shape hunt recording sheet by drawing one object and finishing, “It is a ___ because ___.” Invite several students to share, then collect sheets for assessment.

Resources

• the Shape Hunt Game slide deck
• the shape hunt recording sheet
• Shape cards or large shape cut-outs
• Pencils, crayons and clipboards
• Timer or chime
• Prepared list of safe classroom and nearby objects
• Board or large paper for the class shape sort
• Optional camera or tablet for teacher documentation

Assessment

• During modelling, listen for students correctly naming shapes and using observable reasons such as “four sides” or “a curved edge”.
• During the hunt, check whether students can match objects to a shape and record or draw their findings. Ask individuals to justify one choice.
• Use the final drawing and sentence to identify students who can name a shape and give a relevant reason. Note students who confuse squares and rectangles or rely only on colour or size.

Differentiation

• Support students with a visual display of the four target shapes, real shape cut-outs to trace, partner talk and sentence starters: “I found a ___” and “It matches because ___.”
• Provide a smaller search area and a reduced target of two shapes for students who need less movement or cognitive load. An adult can scribe spoken responses.
• For EAL learners, pair each shape name with a clear image and gesture; rehearse the words “side”, “corner”, “straight” and “curved” before the hunt.
• Extend confident students by asking them to find two objects representing the same shape in different sizes or orientations, and explain how they know the shape has stayed the same.
