This document provides information about 2D and 3D shapes, including how to identify, name, and divide them. It begins with identifying common 2D shapes like triangles, squares, circles, rectangles, diamonds, pentagrams, and hexagons. It then introduces 3D shapes such as cubes, pyramids, cylinders, cones, and spheres. The document explains how to identify composite shapes made up of smaller basic shapes. It concludes with dividing circles and other shapes into equal parts or sections.

1. Shapes are everywhere!
We need to know what they are!

size?
Square
Circle
Triangle
Rectangle

6. Square: Good Job!
• Squares have 4 sides
• All the sides are the same size
• All squares are also rectangles, but not all rectangles are squares.

7. Which is a hexagon?

square
• Pentagram: has 5 sides
• Hexagon: has 6 sides

9. Which is a hexagon?

10. Yes! Good Job!
• This is a hexagon.
• It has 6 sides!

11. Can you name this shape?

13. Can you name this shape?
Hexagon Rectangle
PentagonDiamond

14. Wonderful!
• This is a pentagon
• It has 5 sides

15. 3D Shapes!
Can you match them?
• Cube: has 6 Square sides
• Pyramid: has a square bottom and 4 triangle sides
• Cylinder: has 2 circle bases
• Cone: has one circle base
• Sphere: looks like a ball

16. Which shape is a cone?

17. Oops! Let's look at the shapes again!
• Cube: has 6 Square sides
• Pyramid: has a square bottom and 4 triangle sides
• Cylinder: has 2 circle bases
• Cone: has one circle base
• Sphere: looks like a ball

18. Which shape is a cone?

19. Great Job!
• This is a Cone
• It has 1 circle as a base

20. Can you name this shape?
Hexagon
SphereCylinder
Pyramid

21. Oops! Let's look at the shapes again!
• Cube: has 6 Square sides
• Pyramid: has a square bottom and 4 triangle sides
• Cylinder: has 2 circle bases
• Cone: has one circle base
• Sphere: looks like a ball

22. Can you name this shape?
Hexagon
SphereCylinder
Pyramid

23. Cylinder! Correct!
• This is a Cylinder
• It has 2 circle bases

24. Which shape is a Pyramid

25. Oops! Let's look at the shapes again!
• Cube: has 6 Square sides
• Pyramid: has a square bottom and 4 triangle sides
• Cylinder: has 2 circle bases
• Cone: has one circle base
• Sphere: looks like a ball

26. Which shape is a Pyramid

27. Correct!
• This is a Pyramid
• It has a square base and 4 triangle sides

28. Composite shapes!
• A composite shape is a picture or larger shape made from smaller shapes.
• This house was made from 2 Squares, a triangle, a rectangle, and a diamond

29. Can you tell me how to make this shape?
1 rectangle, 1
pentagram, 2
triangles
1 pentagon, 2
triangles, 2 Squares
1 rectangle, 1
hexagon, 2 triangles.
2 Squares, 2 triangles,
1 hexagon

30. Oops! Let's look at how to make composite
shapes one more time!
• A composite shape is a picture or larger shape made from smaller shapes.
• This house was made from 2 Squares, a triangle, a rectangle, and a diamond

31. Can you tell me how to make this shape?
1 rectangle, 1
pentagram, 2
triangles
1 pentagon, 2
triangles, 2 Squares
1 rectangle, 1
hexagon, 2 triangles.
2 Squares, 2 triangles,
1 hexagon

32. Awesome!
• This looks like it could be a duck.
• It is made of 2 squares, 2 triangles, and 1 hexagon!

33. Portioning Shapes!
• Let’s divide some shapes up!
• What do you do when some one says divide that into fourths?
• Well you put one line down the center of the shape and then one across the
middle; like so!

34. How would you divide a circle into 4 equal
parts?

35. Oops! Let's look at this again!
• Let’s divide some shapes up I!nto equal parts
• What do you do when some one says divide that into fourths?
• Well you put one line down the center of the shape and then one across the
middle; like so!

36. How would you divide a circle into 4 equal
parts?

37. Good Job!
• This Circle has been divided into fourths!
• All of the slices are the same size, so they are equal!

38. All Done!
