[Algebra 1 Spring 2014] Week 11T: 3/25

I highly recommend viewing the Khan Academy videos on Ch. 11-4, the Pythagorean Theorem. I’ve also worked out a few problems from Ch. 11-4 to supplement what we discussed in lecture; #16 & 22 can be viewed here, #30 and 32 can be viewed here.
There will be no class two weeks from today on Tuesday, April 8th, since some of you have STAR testing and I will be returning from a performance in New York.
Tests were handed back in class today. If you are unsatisfied with your score, you may earn up to half of the points you missed by working out the answers to incorrect problems on a separate sheet of paper and handing it in with your test on or before Friday April 4th. Please do not change your answers or make new markings on the test itself. If you want assistance with any of the problems, please let me know.
Finally, there’s a math-related puzzle game called 2048 that’s recently become popular. I found it to be pretty fun, and you don’t have to actually do any math to play it. If you’re interested, you can play here on a desktop computer, here on iOS, or here on Android.
