This is a collection of 10 different algebra puzzles that use 3 different variables which are represented as rectangles, triangles and hexagons. Yes, we know that "adult" algebra uses X, Y and Z, but since this is designed to be appealing for our younger students (and because abstraction is still tough for them) I've used these geometric shapes instead.
I've also limited the kinds of numbers students use by focusing on using 0 - 9 digit cards. This is so your students will not get frustrated when they see a clue like rectangle x triangle = 40. Instead of having to try lots and lots of different combinations with one and two digit numbers, they only have to decide if it is 8 x 5 or 5 x 8.
In addition, this activity is designed to minimize frustration and maximize engagement by using digit cards, which can be placed directly on the question sheet. That way if your students come up with an incorrect answer, they can do a quick-change on the digit cards without having to erase their answers.
And speaking of answers, you don't have to print up a full set of 10 puzzles for each students. Instead I included an answer sheet where your student can record which puzzle number it is and put in the numbers that go with the puzzle, as well as the solution.
The puzzles come in two formats: one leaves it up to the students to figure out the digits to use, while another set of the same puzzle gives a hint on the lower right corner, that tells what digit cards to use. Im sure you can figure out why I did this.
I've included an answer key as well as a "Do It Yourself" blank sheet so your students can make up their own puzzles.
Cool beans, right? Try it out on your kids; you'll see it as a way for them to practice their computational skills, but they'll also be doing higher order problem solving!
