Today JPaul and I worked on arc length and area. We first changed degrees into radians and then substituted those values into the formulas. I reminded JPaul about proper units. When working with 1 dimension we use cm, in, ft, etc. In 2-Dimension we square the units. If we were in 3D, we would cube the units.
Matthew was a little late today so we took some time to begin. We only had time to do some ACT prep problems. We worked on geometry problems and some algebra involving polynomials.
On yesterday's assessment, Linear functions were a topic that Carson scored lower on, so we will be reviewing this content until Carson feels comfortable with it. I gave Carson a mixed review activity. We first started with finding slope: using the graph, using points, and from the equation. Then we practiced graphing the lines in slope intercept form.
Today we continued to work on how to find the arc length of a circle. We recalled the formula: S=r@ where r is the radius and @ is the angle measure. I reminded Andrew that the formula cannot be used when the given angle is in degrees. We first must change them to radians. I gave Andrew a few practice problems where he could change from degrees to radians. Then we used those values for arc length. Next we had a series of Safety Drills that Andrew participated in.
