This sheet helps guide students through the process of adding and subtracting fractions. It includes a chart that will help students find the lcd, and then add or subtract using the vertical z method.

This worksheet should be cut lengthwise and students should be in pairs. Students are timed and will complete their side of the sheet. Once the time is up, students will compare their answers with their partners. Both students should have the same answer even though they completed different problems. Students will discuss any answers that do not match and determine the correct answer together.
