Students’ age range: 14-16

Main subject: Mathematics

Topic: Solids

 

Description: The students will be asked to state the shape of the cross section for cylinders. After identifying such, the teacher will place a question on the whiteboard requiring the students to calculate the volume of a cylinder (that will be drawn). The students will be given a few minutes to attempt calculating the volume of the cylinder. A student chosen at random will be required to place his/her solution on the whiteboard giving rationale for each step made. This will be the beginning of a discussion where students will share their answer to the problem, if different from the one on the whiteboard.
The teacher will guide the discussion giving explanation where necessary to address any misconception the students may have.
The students will then be given problems (including word problems) to which they will independently find the solution. There will be discussions at intervals among the students with regards to the interpretation of the word problems given.
The teacher will review the students’ individual work.
