Stage 1

Exploration: Shapes Around Us

Hello wonderful students! In our classroom and all around us, there are many everyday objects shaped like 2D geometric figures. Let's examine them!

Square

Has 4 equal sides.

Example: Floor tiles, Photo frame

Rectangle

Opposite sides are equal.

Example: Blackboard, Notebook

Triangle

Has 3 sides and 3 angles.

Example: Triangle ruler, Road sign

Circle

Curved side with zero angles.

Example: Wall clock, Coin, Bicycle wheel

Quick Guess Check!

What shape is a classroom wall clock?

Stage 2

Collaboration: Solving a Simple Problem

Work together with your group members to solve a classroom puzzle regarding organizing objects by their geometric shapes!

Group Case Study

Organizing the Math Supply Boxes

Teacher asked Ben and his group to sort math teaching tools into specific storage boxes so the classroom stays neat. Help them place each item into the correct matching container!

Choose the Right Container for:

Item to sort: Drawing Book Cover

Group Discussion Notes

Discuss with your team: Why should a drawing book go into the rectangle box? Because its opposite sides have equal lengths!

Challenge Status: Item 1 of 3

Stage 3

Communication & Presentation: Sides & Angles

Let's present our findings to the class! We will explore in depth the two main components of 2D shapes: Sides (Edges) and Angles (Corners).

Slide 1 of 4

What is a Side (Edge)?

A side is a straight or curved line segment that forms the outer boundary of a 2D shape. For example, a square has 4 straight boundary lines.

What is an Angle (Corner)?

An angle is formed where two straight sides meet at a corner point. A square has 4 corner angles where its sides join.

Daily Learning Reflection

Fantastic job! We have completed our 2D shapes adventure. Now let's summarize what we learned and draft easy-to-understand shape sentences.

Guide to Making Shape Sentences

Name the 2D shape (e.g., Square, Triangle).
State the number of sides (e.g., It has 4 sides).
State the number of angles or special feature (e.g., It has 4 right angles).
Give an everyday object example (e.g., like a floor tile).

"Example Sentence: A notebook is shaped like a rectangle because it has 4 sides and 4 angles."
