Students completed their final test of the year on surface area/volume.
We went through the second review sheet to prepare for the final test of the year on surface area/volume, which is tomorrow.
Students received a second review sheet on surface area and volume. Students had time to work on it in class.
Final test over surface area and volume will be Tuesday, 5/24. Please turn in your books if you have not yet done so. We went over the Practice Test (1 - 6) today. We also examined what is the most cost effective way to wrap 24 candy cubes, see the link below.
http://www.101qs.com/3038-dandy-candies We will turn in books tomorrow. HW: Prepare for the final test on surface area and volume which is on Tuesday, May 2=4th during the regular class period. We watched 2 short videos to review finding the volume of a sphere and volume of a cylinder. Students worked in groups to calculate the surface area and volume of the racquetball and the volume of its container. Then they calculated how much air would be in the container if it contained 2 racquetballs.
HW: Complete the review sheet Today we looked at the last formula, which is the surface area of a sphere. We also went over #6, finding the surface area and volume of a triangular prism. Students were given a review sheet for the last test (on 5/24). I also had the opportunity to talk with each student about their grade.
HW: The surface area/volume packet should be completed. Students were given a rectangular prism and were asked to measure the length, width, and height. Then they calculated the volume and surface area of the prism. Then we went over the formulas for the volume of a sphere and hemi-sphere.
HW: Complete the volume of a sphere and hemi-sphere on 1-8. We went over #5 from homework (surface area and volume of a triangular prism)
We also completed our notes on surface area & volume of a cylinder.

We explained that the surface area of the box it the total area of all the sides (top & bottom included). Then we reviewed the volume of a box as length*width*height (or the area of the base * height of the box).
