The 2nd of ESO students will be diligently working on a new and exciting lesson today, Lesson 14: Surface Area And Volume. As many students quickly absorb lessons in mathematics, working with similar problems and problem-solving in English can be quite fun. Vocabulary terms will be used and reused throughout the problems the students need to solve, and it is enjoyable for them to attack a problem knowing how to both depict the English language used and to solve the equation.
For example, students will need to follow these instructions to complete the problem:
Draw the correct 3D object for each exercise on your notebook, and label it with its measurements.
a) Rectangular prism with l=30cm, w=20cm, and h=10cm
b) Square pyramid with side of the base 5in and height 6in
c) Cylinder with radius 3m and height 5m.
d) Cone with r= 8in and h= 5in.
e) Sphere with a diameter 30mm.
Other problems the students will need to solve include word problems. Here is an example of one they will be working on.
A water tank has been purchased for the farm. It will be used to water cattle. It is an oval shaped metal container that is 2.7 feet tall. The area of the bottom of the tank is 12.8 square feet. If the farm animals drink two hundred seventeen cubic feet of water a day, how many times per day will the tank have to be filled?
Some problems deem to be quite difficult, although with help, the students persevere. The most difficult task they will face may be to create their own word-problems, using specific guidlines to help along the way. Here are the instructions for this exercise as well as the set-up/format to help.
Write 2 different word problems where the solution is finding the surface area or the volume of a 3D object. Solve them and present them to your class.
The shape of a _____________________ is a ______________ that measures
___________________________________. Find the __________________.
