O, Pythagorus!

I am working through geometry for the fifth and final time.  This has been a tough course for Andrew, and having tried everything without too much success, today I decided to work very intensely with him.  I explained the lesson to him and then sat right beside him and talked him through each problem.  We checked each answer as he did it, and the immediate feedback seemed to help.  We did two lessons this way today, and his score on the second one was MUCH higher than they’ve been in the past, so it looks like for the short term, I will once again be intimately acquainted parallelograms, trapezoids, right triangles, and their relative sides, angles,m and areas.

You would think that after have done high school geometry five times (Patty, Katie, Jessica, and Josiah), I would have it down fairly well, but tonight I was completely stumped.  I had to ask Scott to figure out and explain to me why, in the case of a certain proof, Andrew’s and my answer of (a-b)^2 really was equivalent to the answer book’s answer of (b-a)^2  (and therefore correct) AND how on earth the book ever derived (b-a)^2 in the first place.  Scott did explain it, but for the record, Mr. Jacobs, you really should have listed both answers as correct options on lesson 9.5, problem 38; especially since the answers to problems 39 and 40 both depended on the answer to that one!  I do want to be gracious, but honestly, these kinds of frustrations just seem to be too much for my 50+ year-old brain to handle well at 9:00 PM after a long and busy day.

While it has truly been deeply gratifying to have been able to homeschool kids for lo, these past 24+ years, I will confess that checking math answers and doing related corrections is one aspect of the process I will not miss whenever I finally hang up my “homeschool mom” hat.
