Today in class students took the 3 D Geometry Test on area and volume. We will finish on Monday.

Today in class students looked at definitions and relationships of exponents. Hopefully a few notes have been added to the page of definitions...good discussion today.
Today in class students practiced more with the Pythagorean theorem, and began a mini project designing Math Town. It is due Friday. And we will test Friday with another day of area and volume practice tomorrow.
Today in class students learned about and worked with the Pythagorean Theorem. Fun stuff.
Answer to the Lancelot puzzle: ICURABUTLN Today in class students tested their knowledge of finding the volume of different shapes. Every night the homework has been to review vocabulary and formulas. They were not doing so well today. I am surprised.
The quiz was not for a grade, but a tool to self check - how well do I know the formulas and how to use them? Halfway through the quiz time, I allowed students to get their bookmarks (they had a much earlier assignment to create a bookmark with all of the formulas from the whiteboard so they could use them during class and to study at home) out to use. Fully 2/3 of the class did not have a bookmark to use. This is the real problem here. Just saying. Today in class students figured out the pattern of scale factors for changing the size of geometric figures. (It depended on how many measurements were changed... and circles increased area more than doubling with the radius changes. It was cool to watch.)
Today in class students reviewed Tasks 3 and 4 for 2d and 3d geometry. We moved on to use the textbooks for more surface area problems. Since we have the strength of collaboration in the classroom setting, I began the task with the harder problems first. So we began with #16 and were working our way down to #1 when class ended.

Hmm. There's another problem when only 1/4 of the class has bothered to watch the assignment. When we figured out what the difference is, we spent a few minutes re-working a couple practice problems before checking over them.
