Surprised

For the last few weeks we have been working on shop math. I have been trying to teach it in different ways to keep the interest of the students, which is not too easy.
This week while teaching surface area and volume, I gave the students a piece of isometric graft paper and demonstrated how to use the paper to draw some three dimensional cubes. I then had the students try drawing some cubes to be sure that they could grasp the concept. I used my doc. cam with some real cubes to give them a good visual of what they would look like. I stacked some cubes after that and had them draw the stacked cubes. When they mastered that which didn't take too long, I had them write their initials in cubes. This took a little longer because some of the letters can be difficult to draw. When they were finished with that, I had them figure the surface area and volume of their initials.
I really wasn't sure how the lesson would go over, but I was surprised that the students liked it and put some really good effort into it. I was also surprised that I actually had some veteran teachers that are planning on using that lesson in the future.
In the lessons that followed, I built upon that and had them drawing more complicated isometric drawings, which I think is important for teaching spacial relationships and visualization. I think this will help me in the future when we start designing and creating duct work.
