## EXPLORING SURFACE AREA IN YEAR 10 MATHS

Year 10 Maths Methods students undertook an investigation into the surface area of 3D objects. Students were initially given a 2D shape or a 3D object and their first task was to find their team by matching up the 2D faces with the corresponding faces of the 3D objects. The objects included a pyramid, cylinder, triangular prism, cone and chest.

Once in their groups, students were required to physically measure key dimensions of their object and faces in order to calculate the total surface area of their 3D object. Then students were able to team up with their friends and find the total surface area of the remaining 3D shapes spread throughout the room.

STUDENT REFLECTIONS:

On Wednesday 29 May the Year 10 Maths Methods classes all did an activity to help expand our knowledge of geometry and to learn about total surface area on 3D shapes. Using different shapes of paper, we were able to use each of the different shapes to make a big 3D object. This exercise taught us how to calculate total surface area and was just overall a really fun change to the normal math exercises.

I could tell people were enjoying the activity and it was a great segue to the measurement topic exercise. I'm sure my class would agree that it helped us grasp and better understand it to be physically seeing and touching the shapes and was a great introduction to total surface area in Year 10 Maths Methods.

The new styled lesson we did was a fun way to learn. Through collaboration and visual aids, it suited diverse learning styles and as a visual learner, it totally clicked for me faster. Moving around the classroom made it feel more fun and interactive too and made a new dynamic learning environment. Making these lessons can add a new twist to learning math.
