### PRODUCT DESCRIPTION

This CUBE AND STACK PUZZLE asks student teams of three to identify right, acute, and obtuse triangles using angles. Each student gets a different cube template (1 of 3). Each student in the team cuts out and constructs their cube. They then work together to stack their 3 cubes so that 3 facing sides describe the same triangle. It is challenging, but my students think its 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. I have a set of templates in a folder should students finish daily work early and want to earn extra credit.

Cube 1 lists the triangles (right, obtuse, and acute). Cube 2 has pictures of triangles. Cube 3 asks students to stack the cubes on top of each other based on the information given about angles in triangles. Each cube has 6 sides, so some information may distract students (similar to those found on standardized tests). Know that all information is about triangles, (i.e. What is the relationship among the measures of all angles of these triangles?)

After the stack is correct, students have a worksheet to complete and submit.

Your purchase includes a sample lesson plan, directions, three colorful templates with students directions and objective/question of the day, a worksheet, answer key, and 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 for building the cubes. Each team will need scissors and glue. Elmer's white glue is preferable to glue sticks. Use the glue sparingly otherwise the paper will 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.

One reminder, some students are going to make perfect cubes, others are not, but the learning, teamwork, thinking are the focus. Have students help each other. I've always had a few "cube building" whiz kids that help others. I offer other cubes, and have found that 4 CUBE AND STACK PUZZLES spaced throughout the year is motivational.

FYI: cubes are 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 two dollars more.
