The document explains the difference between plane figures and solid figures, highlighting their dimensions and characteristics. Plane figures are two-dimensional shapes such as squares and circles, while solid figures are three-dimensional objects like cubes and spheres. It includes activities to help students identify and categorize these figures based on their properties.

7. GUESSING GAME:
I am a solid figure. I have no faces
or edges. I am round.
I have 3 sides. My sides are not always
the same. I have 3 vertices.

8. GUESSING GAME:
I am a solid figure. I am round and have 1
round face. I have a point and 1 round edge.
I am a solid figure. I have 6 faces. 8 vertices
and 12 edges, all equal.

A boy visited a toy store and he found the ff.:

10. Use the four-step plan to solve the problem.
2.Plan:
Strategy: Use the definition (to identify plane
and solid figures)
1. Understand:
a. What is asked?
b. What are the given facts?

11. 3. Solve:
Plane figures are closed figures whose points lie on the same
surface. They are flat and have only two dimensions- the length
and width. Ex. Square, triangle, circle, rectangle
Solid figures are 3-dimensional figures that have length,
width, and height. Ex. sphere. cube. Rectangular prism,
cone, pyramid.
Answer: The top of the table, floor, wall, receipt and the face
of a card are plane figures while the ball, toy car, toy plane,
dice, robot, toy block, & Chinese bagua are solid figures
because they are not flat & have 3 dimensions.

12. 4. CHECK:
•THE TOP OF THE TABLE, FLOOR, WALL, RECEIPT AND THE FACE OF A
CARD HAVE ONLY 2 DIMENSIONS – LENGTH & WIDTH. THEREFORE,
THEY ARE PLANE FIGURES. AND THE BALL, TOY CAR, TOY PLANE,
DICE, ROBOT, TOY BLOCK, & CHINESE BAGUA HAVE 3 DIMENSIONS
– LENGTH, WIDTH & HEIGHT. THEREFORE, THEY ARE SOLID FIGURES.

14. ASK THE FF. QUESTIONS:
What is a plane figure?
A plane figure is two dimensional figure which
possesses an area but the volume of this figure is zero.
The examples of plane figures are square, circle,
rectangle, triangle etc. Plane figures can be drawn on
a paper. The unit of area of a plane figure is square of
unit of length. The study of plane figures is called
plane geometry.

15. ASK THE FF. QUESTIONS:
What is a solid figure?
The three dimensional figures are called solid figures.
These figures have an surface area as well as a
volume. These figures cannot be drawn on a paper. The
examples of solid figures are cuboid, parallelepiped,
football, solid sphere etc.

16. GROUP ACTIVITY:
1.Divide the class into cooperative groups of five.
2.Each group is assigned a solid figure and given their
shape to examine .
3.They draw a picture of their shape, and list its
characteristics, including: the plane figure that
creates its faces.

17. PAIR-SHARE: DISTRIBUTE THE ACTIVITY SHEETS
Cut the above graphics and glue them under suitable categories.

18. WHAT IS THE DIFFERENCE BETWEEN A PLANE FIGURE AND A SOLID FIGURE?
•THE DIFFERENCE BETWEEN PLANE AND SOLID FIGURES IS IN THEIR DIMENSIONS.
WHERE A SQUARE IS A PLANE FIGURE, ITS 3D COUNTERPART, THE CUBE, IS A SOLID
FIGURE. THE SAME COMPARISON EXISTS BETWEEN A CIRCLE, OR PLANE FIGURE, AND
A SPHERE, A SOLID FIGURE. INDIVIDUALS CREATE PLANE FIGURES BY CONNECTING
POINTS ON A GRID TO CREATE 2D GEOMETRICAL SHAPES. THE SAME SHAPE TAKES
ON EXTRA DIMENSION BY ADDING ADDITIONAL POINTS AND LINES TO GIVE THE
SHAPE HEIGHT, WIDTH AND DEPTH.
