These 3 puzzles should keep your students baffled for a long time! Each one has the same idea: arrange the pentominoes on the grid so that they are “locked” together. These puzzles develop all kinds of geometric thinking, including slides, rotations and flips.
The puzzle pieces should be printed on different colored card stock, so that students know which pieces go with different puzzles (although since the grids are different sizes, they shouldn’t be readily confused.) If students are “stuck,” you can give them hints by placing one of the pieces in the correct place.
For students who need additional hints, you may want to show what order the pieces go in (for example, “the staircase goes in the upper left, and the “z” goes in the lower right” in the 2 piece puzzle. Incidentally, each puzzles can be solved in 4 different ways, depending on how it goes across the grid (from right to left, top to bottom; left to right, top to bottom; right to left, bottom to top; and left to right, bottom to top.)
The solutions presented here are just one of the 4.
These puzzles are excellent ways to demonstrate transformational geometry while engaging students in an activity that ranges from challenging to very challenging. Try them out and see how your students like them!
! In my nearly three decades of experience teaching mathematics at the K - 8 level, I have always started with the idea that an expert teacher working with interesting and innovative materials will create conditions ideal for learning. Therefore, I work with teachers from every direction: I work to coach individual teachers on how to bring innovation to their practice, while incorporating activities which will bring their students to ever higher levels of understanding. I also conduct workshops around the country to educate teachers about the cutting edge of mathematics education, including neuroscience, concept development and math anxiety. I am also available for curriculum design and teacher coaching. Please email me at firstname.lastname@example.org if you are interested in these aspects of my work.
