Geometry; 4/27

We continued our work with area formulas today by taking a look at how to figure out the area of regular polygons.  A new vocab term -- the apothem -- was introduced today and we went over how to use it in the various shapes we were working with.  We used several special right triangle shortcuts in order to figure out the areas of the regular polygons.  After a few examples together, the students got started on their assignment.

Geometry; 4/26

We continued our work with areas today by taking a look at how to work with the areas of trapezoids.  We reviewed some earlier concepts of trapezoids together and then went over how use the area formula.  After 4-5 examples together, the students then got started on their assignment.

Today's lesson focused on how to work with the area of figures to determine the probability of an event occurring.  We went through the basic concept of what probability is and then how to apply it to various types of problems involving area.  We went through 4-5 examples together before getting started on the assignment.

Geometry; 4/25

We continued our work with areas today by taking a look at the area formulas for the parallelogram, the rhombus, and the triangle.  We went through how these formulas are derived and then 1-2 samples of each type of problem.  We reviewed the ideas of trig ratios and pythagorean theorem and how to use these tools to get the necessary dimensions.  The students then got started on their assignment at the end of the period.

We continued our work with areas today by taking a look at how area and perimeter ratios can be determined between similar shapes.  We reviewed how to find and work with the scale factor, and then showed some short cuts in doing these area ratio problems.  We went over 4-5 examples together before getting started on the assignment.
