This CUBE AND STACK PUZZLE asks student teams of four to classify real numbers. Each student gets a different cube template (1 of 4). Each student in the team cuts out and constructs their cube. They then work together to stack their 4 cubes so that 4 facing sides describe a type of real number including integers, whole numbers, rational numbers, and counting numbers. It is challenging, but my students think it's fun. I've used this activity for review, to teach a concept after a brief introduction, in after school help sessions, and to assist students who want to make a set of cubes to help them study. An extra set of templates is available for extra credit if students finish their daily work early.
Cube 1 lists types of real numbers (integers, rational numbers, whole numbers, counting numbers). Cube 2 has descriptions of each type of number. Cube 3 gives examples of each type of number. Each cube has 6 sides, so there is additional information on irrational numbers and real numbers that can distract students. There are four sides that can be aligned on irrational numbers, but this is NOT the challenge.
After the stack is correct, students have a worksheet to complete and submit.
Your purchase includes a sample lesson plan, directions, four colored templates with student directions and objective/question of the day, a worksheet, and an answer key. It also has the key for the correct stack formation.
Run off a set of templates for each team. (Black and white works as well as color). Our school uses cheap copy paper and it works fine. Each team will need scissors and glue. White glue is preferable to glue sticks. (But glue sticks work, too). Use the glue sparingly, otherwise the paper can get soggy. I strongly encourage you to make your own set. It will help you answer student questions when they ask about where to fold the cubes. You can add your cubes to your math center as an activity, too. Practice stacking your cubes! Remember, the puzzle stack key is included in your purchase.
One reminder, some students are going to make perfect cubes, others are not, but the learning, teamwork, and thinking are the focus. Have students help each other. There are always a few "cube building" whiz kids that can help.
I offer other PUZZLE sets, and find that 4 CUBE AND STACK PUZZLES during the year increases motivation in class.
FYI: each cube fits 8.5 x 11 in paper. Each cuber is about 2.25 x 2.25 x 2.25
If you are interested in having students make a holder for their cube set, let me know.
Thanks, and have fun! Also, I have hard copies of this available. Just let me know. The hard copies are three dollars more (copying, shipping, handling)
