Segment Addition Postulate Color by Number

In this activity, students will apply the segment addition postulate to find missing lengths of line segments while they have fun coloring! The problems are given in line segment format and word format, and they include various levels of difficulty (including solving for a variable using the segment addition postulate). Once students find the missing lengths, they will color their answer according to the color given to reveal a beautiful, colorful mandala.

This no-prep activity is an excellent resource for sub plans, enrichment/reinforcement, early finishers, and extra practice with some fun. It is especially useful for end-of-year practice, spiral review, and motivated practice when students are exhausted from standardized testing or mentally “checked out” before a long break (hello summer!). Color motivates even the most challenging students and the students get a fun chance to practice their essential geometry skills. In addition, the finished products make fabulous classroom decor!
