Geometry - Graphing Special Lines-Parallel and Perpendicular-Two Investigations
This activity contains two investigations. First Investigation:• On the graph provided, students graph each of the pairs of points and draw a line through the pair of points.• The students study the two lines and conjecture that the two lines are parallel.• Then the students find the slope of the two given lines to notice that when the lines were parallel the slope of the two lines are equal.• Students repeat these three steps with four more points. • After students know that two parallel lines

Geometry - Area and Perimeter - An Exploration on the Geoboard
This activity is designed to be used with a geoboard (11 x 11 pegs). An alternative for geoboards is included in this package (index size cards with 11 x 11 geoboards). Students explore the meaning of perimeter and area by constructing polygons on the geoboard with rubber bands or drawing line segments that represent the rubber bands on the index size cards. The activity can also be used with Communicator Clearboards, available from Educator's Outlet and a copy of a student grid. After the st

AREA OF TRIANGLES USING GEOBOARDS
This activity will lead middle school students through constructing triangles and rectangles that are related to each other to determine a method for finding the area of a triangle. There are three parts of the investigation:• Finding the area of triangles where there is one horizontal and one vertical side• Finding the area of triangles where there is one horizontal or one vertical side• Finding the area of triangles of general triangles.The investigation ends with the students summarizing what

Trig - Law of Sines - PARTNER PAIRS
Partners will work on separate columns of problems that will result in the same answer to check each others' work.There is a set of 10 problems for each partner to complete. 6 problems are on finding missing sides and 4 problems are on finding missing angles.The RELAY RACE has some of these same problems. The RELAY has 32 different problems. This product has 20 problems.Posted: 11/5/14 so 50% off through 11/8/14
