Here's a fun activity to review the basics of line segments. Students will apply the segment postulate addition method and use algebra to find the length of segments. Students must navigate through a digital maze and answer 18 questions. One question is shown on the maze as the students begin the activity. A path appears, and the next question pops up as the students answer correctly. Incorrect answers reveal nothing, and students must reattempt the question to move along successfully in the maze. Students will continue on the path until the end. This NO PREP, self-checking digital maze is great for homework, assessment, and math centers. Available in Google Sheets and a printable PDF. An answer key is included.
