Practice using the segment addition postulate with 3 different levels of collaborative worksheets for students. Pairs of students complete different worksheets of 8 problems each that have the same answers. Great activity for students to check their work, and self checking.
Versions A/B find segment lengths with integer answers--straight forward calculations and the beginning level.
Versions C/D have expressions for some or all of the segments and students need to write equations to solve for x.
Versions E/F have expressions for the segments, students write equations to solve for x and then use that value to find the indicated segment length.
Use on one day for different levels of learners in the classroom or different days. You can also use as homework checks using one of the versions and follow up with the matching version the next day to have students check their homework answers.
