Combine and Conquer 
Copy onto cards the following names of geometric figures: acute triangle, right triangle, obtuse triangle, scalene triangle, isosceles triangle, equilateral triangle, parallelogram, trapezoid, rhombus, square. Shuffle the cards and divide them evenly.
Each partner draws and labels the figures shown on his or her cards. It may be possible to draw a figure so that more than one name applies to it. Each partner gets 1 point for each single figure that is drawn correctly and 10 points for a correctly drawn figure with two or more labels. Trade papers and check each other's work.
