Kellan said that he missed school yesterday because his parents had a big argument. We didn't discuss details because he seemed to want to move on. I told him that whatever disagreements his parents have between them, they always do the best for him and his sisters. He agreed with that.
Today Ben was in a new room and seemed in a good mood because of it. He said he was slow moving to get back into the swing of things. I told him I felt similarly lol. We discussed what we have covered so far this year and what we still need to cover. Then he listened as I reviewed exponent properties. We discussed the square root and the idea of it being a fraction power. I realized Ben and I need to review radical properties.
Today Joshua and I discussed the graphs of sinusoidal functions, their period, frequency, amplitude, midline and phase shift. We first started by discussing the square root function and what we know about the transformations. Then we applied that to the sine function. Joshua was able to see how students could make mistakes when they see 3x-3 as a shift to the right 3. However, if you consider that 3x-3 is really 3(x-1), then you see that it's a shift to the right 1 (not 3). Joshua then practiced graphing sinusoidal functions given the equations. He also got practice writing the equations functions given it characteristics.
Today we began by reviewing degrees and radians (how to go from one version to the other). Then we discussed how to go from degrees/minutes/seconds to their decimal form. JPaul was a bit rusty at first, but with a few reminders he was able to recall. Next, he helped me with some Easter decorating. I needed his long arms to help me reach high up! :)
Today we continued in the chapter on 3D figures. We recalled on the board the formulas we need. We recalled how to find the surface area and volume of spheres, cylinders, and cones. Then we did an application activity. We looked up the diameter of a tennis ball to be 6.54 centimeters. Then we considered a tennis ball can with 3 balls stacked inside touching end-to-end. I asked Carson to determine the amount of sand we would need to fill up the can completely. Carson worked to determine the volume of each sphere. Then he found the volume of the cylinder. Then he subtracted the volumes of the spheres from the entire volume.
