Building the world! In this chapter, we'll learn to name 2D shapes and see how they move with half and whole turns!
Main skills from this lesson
Straight or Curved?
Every drawing is made of lines!
vs
Shape Tip: Feel the edge of your desk—is it straight or curved?
Look at an APPLE. What kind of lines does it have?
Meet the Shapes!
Shapes have special features like sides and corners:
Shape Secret: A rectangle is like a square that's been pulled longer!
Which shape has 3 sides and 3 corners?
Are They the Same?
To be 'twins', shapes must have the same name AND the same size!
Shape Detective: Look for the vertical oval. Can you find its perfect match?
If you have a tall, skinny rectangle, which of these is its perfect 'twin'?
Which One Doesn't Belong?
Sometimes, a shape tries to hide in the wrong group!
¢ | ”“”
Detective Tip: Check the number of sides to find the imposter!
I have 4 equal sides and 4 corners. Who am I?
Shapes You Can Hold!
Solid shapes are all around us. Can you match the object to its 3D shape name?
🎲
3D Tip: Cubes have equal sides everywhere, but cuboids can be long and skinny!
What 3D shape is a DICE?
Find the Imposter!
Sometimes a different 3D shape tries to join the group. Can you find them?

Tracing Secret: If you trace the bottom of a juice can, you get a Circle! If you trace a block of wood, you get a Rectangle!
If you paint one side of a perfect CUBE and press it on paper, what 2D shape will you see?
Time to Spin!
Objects turn in different ways:
Types of Turns:
¡ (Half) | (Whole)
Turn Tip: A whole turn is like doing a 360 spin on your feet!
If an arrow is pointing UP and you give it a HALF TURN, which way will it point?
Clockwise or Anti-clockwise?
Turns can go in two directions:
Turn Fact: Did you know that 2 half turns make 1 whole turn?
™ vs ™¦
Turn Math: 1/2 + 1/2 = 1 Whole! Turning halfway twice gets you home.
How many HALF TURNS do you need to make ONE WHOLE TURN?
How Does it Turn?
Is it a Point or a Line? Is it a Half or a Whole turn?
vs |
Turn Master: Remember, a half turn is like doing a handstand—everything flips!
If you give an ICE CREAM CONE a half turn, what happens?
The Half-Turn Secret!
Some shapes look very different when they flip, but some stay the same!
S S |
Shape Fact: Shapes that look the same after a turn have 'rotational symmetry'!
If you give a CUPCAKE a half-turn anti-clockwise, how will it look?
Can You Solve the Coloring Puzzle?
Use these clues to find the right colors:
The Solution: Circles are Green, Triangles are Blue, and Squares are Red!
Logic Tip: Sometimes you find the answer by cross-checking what a shape *cannot* be!
If circles are green and triangles are NOT red, what color must the triangles be?
The Final Shape Challenge!
Let's test our turning skills one last time:

Chapter Goal: You've mastered 2D and 3D shapes, and you're an expert at turning them around!
If an arrow is pointing UP at a FLOWER, where will it point after a half turn?
