Reply To: Lesson 2-4 Question & Sharing

Original Problem:

Algebra Use the diagram at the right for Exercises 29–32.

29. If AD = 20 and AC = 3x + 4 Then find AC and DC. (the diagram is at the end of the post)

A) I would start by just showing the class the diagram of the segments and ask what they notice about the picture. Then I would ask them to come up with some possible questions that could be asked about the diagram.

B) Along with the type of questions that could be asked about the diagram what type of information might be need to answer these questions.

C) Next, give them AD = 20 and have the students come up with all the answers they can answer based on using just this information

D) Finally, I would give the last bit of information about AC = 3x + 4.

E) I might ask the class with this given information is there any way to find the length of ED?
