We end another week and the last full school week of December. Next week has only three school days and Wednesday is for the class parties. Mine (homeroom) is from roughly around lunch until 3:00 when I take them to specials.
The weekly parent email has been sent home and I have attached a copy of the energy unit study guide.
In math, I reviewed a lot of content such as multiplication along with area and perimeter during 1st block followed by the weekly warm-up quiz and exit ticket. Since this is the last day on the exit ticket, it has been averaged and sent home with the other graded work.
In second block, I extended their knowledge of area and perimeter by doing a lesson on area of right triangles. All they do is multiply the two numbers (base x height) and then divide by two since right triangles are half the size of a rectangle.
I also went over the area of "L"-shaped figures. The trick for solving that is to split it into two separate rectangles (or squares), calculate the areas of each, and then add them up. A run-down of it is in the second video.
In science, I did a few demonstrations of some of the properties of light and one experiment. We tested to see which type of prism, glass or acrylic, produced the brightest and clearest rainbow. The glass was the clear winner.
Below is a few shots of me demonstrating how light travels in a straight path. I used a green laser and beamed it through a clear acrylic rod.
