Intro Activity (30 min)
Teacher asks the students,Have you ever seen train tracks or the edge of a ruler? Those are straight and go on and on. That's what a line looks like in math!”
You can also show things like:
A laser beam in cartoons
A tightrope
So, line is straight and endless in both directions (introduce this simply
Show lines in the classroom (edge of table, window frames)
Draw this on the board:
<-------------------------->
A B
Say:
> “This is a line. The arrows mean it keeps going forever. Even though we see just a part of it, imagine it neverObjective
Draw examples: straight line, curved line, zigzag line.
Then use flashcards to introduce each shape: triangle, square, rectangle, pentagon, hexagon
For each shape:
Show shape visually.
Count sides and corners.
Ask: “What does it remind you of?” (Ex: “A triangle looks like a slice of pizza.”)
Draw examples from real life (windows, stop signs, etc.)
Mini Activity: Ask students to find one object in the classroom that matches one of the shapes.
Main Topic/ Activity
Build-a-Shape with Lines (35 minutes)
From Lines to Shapes” Group Challenge
Students work in small teams.
Provide materials: sticks, pipe cleaners, or yarn for lines; clay balls or stickers for corners.
Task: Use lines to build these shapes:
Triangle (3 lines)
Square (4 equal lines)
Rectangle (2 short, 2 long lines)
Pentagon (5 lines)
Hexagon (6 lines)
Group Roles
Connector (adds clay/sticker)
Shape Checker (counts sides)
After each shape, pause and reflect:
“How did your group work together?”
“What made this shape different from the one before?”
Shape Collage & Self-Expression (30 minutes)
My Shape World
Students create a drawing or collage using at least 4 different shapes to make a scene (e.g. robot, house, city, animal).
Encourage labeling each shape and writing how many sides it has.
Gallery Walk & Wrap-Up Discussion (15 minutes)
Students walk around, observe others’ creations, and leave a kind sticky note (“I love your triangle sun!”).
