Disc 8: Math B

Disc 8: extends the ‘math concepts’ approach, with examples of more advanced functions.


Disc 8 extends the ‘math concepts’ approach, with examples of more advanced functions, probability and combination problems, logical statements, and compound interest. The bulk of this disc, however, is devoted to geometry as it is tested on the SAT. This disc is especially helpful to students who may have had trouble with geometry as it is presented in high school. For example, although proofs are not covered, area, length, slope, volume, special right triangles, similar triangles, arcs, sectors, volume, surface area, and perimeter are all explored–and these are all covered in the way they are tested on the SAT.

Contents [Index numbers, found in the lower right-hand corner of each panel both on-screen and in the workbook, are formatted Disc#-Panel#. The first number refers to the disc the lesson is on, and the second number indicates the starting panel.]

    About to start filming instructional stuff again–this time, I want to do a series of short videos about how you can get the most out of each disc of DVDs4theSAT / SATTutorInABox.

    The SAT is a standardized test designed to measure basic critical reading, math and writing skills. Most colleges and universities request ACT or SAT score results from applicants. Students may usually take their test of choice, but it is best to check with schools of interest before selecting (unless the student plans to take both
