DOWNLOAD EBOOKSixty pages of geometric puzzlers, printable handouts to help your students problem-solve with triangles and rectangles. Level ONE: 20 pages: Students answer four questions about triangles or rectangles per page, determining how many are shaded, how many touch the edge of another, how many stand alone, and how many there are in total. Problems increase in complexity as students work with twenty to thirty triangles and rectangles per page.Level TWO: 10 pages: Students answer five questions per page, as other polygons are added to each design, determining how many are shaded, how many touch the edge of another, how many stand alone, how many are inside another, and how many there are in total. Students work with thirty or forty triangles or rectangles per page.Level THREE: 20 pages. Students create their own geometric puzzles by following six sets of directions that tell them how many triangles they must make, how many must be shaded, how many must be within a given polygon (trapezoid, parallelogram, rhombus, pentagon, hexagon, star, or arrow), how many must stand alone (not in any shape or touching any edges) and how many must overlap another triangle. I have provided an answer key for all the problems in level one and two, so these activities are ready to be used with the whole class or in a math center, for homework or for fun.
