Geometry 6-2 Properties of Parallelograms

Notes: Half-Sheet Tabbed Booklet Foldable

As I told S the other day, once I realized that kids were actually writing down the same information on the foldable as they would have for regular or holey notes, I decided I liked using them.

This booklet consists of three half-sheets (lengthwise) that are folded into a booklet with five tabs and a title page:

Properties of Parallelograms
2 pairs of \parallel sides If a quadrilateral has two pairs of parallel sides, then it is a parallelogram.
opp. sides \cong If a quadrilateral is a parallelogram, then opposite sides are congruent.
opp. \angles \cong If a quadrilateral is a parallelogram, then opposite angles are congruent.
cons. \angles supp. If a quadrilateral is a parallelogram, then consecutive angles are supplementary.
diagonals bisect If a quadrilateral is a parallelogram, then the diagonals bisect each other.

I also gave each student a set of parallelograms to cut out and glue in each page to be labeled appropriately.

We didn’t get finished, but it’s okay since I had planned to spend two days on parallelogram properties.


Algebra Linear Equations Review 1

January 24, 2010

Since the Chapter 5 Test grades were so low, we decided to spend two days reviewing how to do it. Based on how the lesson went, S & and I both think we should use this to teach the lesson in the first place. S created a class worksheet consisting of sets of problems of increasing difficulty.

Their assignment for each problem was to write the equation for the line in slope-intercept form. The first set gave them the slope and y-intercept. The second set gave them the slope and a point. The third set gave them two points. That’s as far as we got on the first day, but we’re going to continue next time by having them write the equations from graphs.
