One of the things I meant to do with my elementary math class (the one that got canceled due to low enrollment):
- Tangrams — A Way to Visualize Fractions, Geometry, and Algebra
[Ignore activity #6. The pages that go with it are missing from the file.]
And then we would play around with Tangram puzzles, and perhaps make up a few of our own.
Advanced Tangram Puzzles
If I were to do a tangram unit with older students, I would be sure to include a few of these tidbits from Archimedes’ Laboratory:
- A curious paradox
Scroll to the bottom of the page for a wonderful little puzzle.
15 more tangram paradoxes to challenge your students.
- Math relations between the 5 shapes which form the Tangram puzzle
Areas, perimeters, and still more puzzles. Kitten loves the banner image!
Can You Put These Together?
If your students like Tangrams, you may enjoy playing around with a few other dissection puzzles. My favorites:
For Further Study
- The Puzzling World of Polyhedral Dissections
Explore the history, geometry, and practical construction of 2- and 3-dimensional puzzles. Woodworking tips included!
