Great collaborative activity where students practice finding the exterior angle of triangles.. Partner A works out his problems while Partner B works hers. When they have finished, they compare answers. If the same--move on, if different, they work together to review their work and find the error.
Includes 2 different pairs of worksheets so you can use one set for homework, or a different day or as a filler when unexpected absences occur. Great for differentiating in the classroom. Use the included exit ticket also as an entrance ticket the next day or a quick assessment.
Have an odd number of students? No problem, just have 2 A Partners or 2 B partners and three students can work together,
Version A/B has integer for measures.
Version C/D has expressions. Students will need to set up and solve an equation to find the measure.
❄️2 pairs of worksheets A/B and C/D
❄️2 page exit tickets--6 different versions
