Lesson Plan version 1.1 activities
1. On a sunny day, take your students to the school playground or any open area near the school building where the shadow of the building falls. Ask a student to stand near the shadow of the building in such as manner that his/her shadow lines up with the shadow of the building. Measure the length of the student’s shadow and the building’s shadow. After coming back to
the classroom, measure the height of the student. Use the ratios and proportions to find out the height of the school building.
2. Ask students to bring their old toys, which are actually smaller models of real things. For
example, toy cars, buildings, aeroplanes, tanks and stuffed toys. Before coming to the class,
students should also find out the approximate size of corresponding objects in real life. They
can use the internet or any other resources such as library to find out this information. If they
do not have access to these resources, you should help them in finding out the information. Now, the students need to measure the height and length of their toys. Then, they can use ratios and proportions to find out how much these toys are scaled down as compared to their real life counterparts.
