TeacherStudent Activities A. Warmup
Session Begin the lesson by recalling the prior knowledge of
students on the following topics:
Recall the formulae to calculate the surface areas
and the volumes of different basic solids. Then, show different objects (or their images) that
are made by the combination of different solids. 
2 
Teacher’s
Explanation Now teacher will provide complete
explanations of all the formulas of the solid figures and ask the students to
learn these formulas. Following solid figures need to be discussed here.

3 
Combination of solid
Figure. Here we combine two or more solid figures and then find the surface area and volumes. Teacher will explain the method of finding the surface area and volume in the combination form. 
4 
Surface
Areas and Volumes: Clay Activity In this activity, students will calculate
the surface areas and the volumes of the combination of solids. In this activity, students
with the help of clay make some solid figures and will calculate the change, if any, in the
surface area and the volume of a solid when it is converted into different
solid or multiple solids, either of the same or different shapes. Explanation
of the Activity Divide the class into two
groups. Bring some modeling clay to the classroom. Ask a group to shape the
clay in any of the basic solids, such as cube, cuboid, cylinder and sphere.
They need to take the required measurements and calculate the surface area
and the volume of the solid that they have made. Now, the other group should
break the solid and make numerous smaller solids from the clay. Then, they
need to take the required measurements and calculate the surface area and the
volume of the smaller shapes. Thereafter, ask both groups to analysis the
relation between the surface area and the volume of the original solid and
the new solids. Conduct a similar activity to prove that when the shape of a solid
object is changed, its surface area changes but the volume remains constant.
For this activity, change the original basic solid into the basic solid of a
different shape. For example, change a cube
into a cylinder and compare the surface area and the volume of the cube with
the cylinder. 
5 
Practice Work Now
teacher will explain the method of finding surface area and volumes by taking
some examples from NCERT book. Teacher will also provide some questions to
the students for practice 
6 
Practice with combination of solid figures Teacher will also explain some other mixed problems [for the problems of combination of solid figures, not more than two solids be taken in combination] and should provide sufficient number of problems to the students for practice. REFERENCES: 
 Different shapes of solid figures.
 All formulas and all important concepts related to the surface area of solid figures.
