Today we worked on area and perimeter of quadrilaterals in the coordinate plane.
We practiced more of the "surrounding rectangle and subtract the right triangles" area strategy with a warm-up. We also made sure everyone understood the best strategies on last night's homework - area by adding together parts.
We practiced more area problems for triangles and quadrilaterals and then learned about finding perimeter of the same figures. Specifically, to the find length of a side that is not vertical or horizontal, you use the Pythagorean Theorem and treat the unknown side as a hypotenuse.
HW #5 is attached and has all of these strategies used. There is an example for problem #1.
If you don't have your notes over quadrilateral definitions, it is on the previous block's blog entry.
HW #5 is due Monday morning!
Students also saw there tests over right triangles. Those who made below 68% need to come next Thursday during advisory for re-teaching.
Those who have not taken the test need to do so tomorrow during your lunch hour.
