Assessment Problem:
Question 1a: Write a story problem that can be formulated by the equation: x+5=8.
Question 1b: Reword your story problem so that it can be formulated by the equation 2x+5=8.
Question 1c: Reword your story problem so that it can be formulated by the equation 2x-5=8.
Question 1d:Reword your story problem so that it can be formulated by the inequality 2x-5<8
(Question #1 can be modified to have variables on both sides)
Mathematical Issues:
Students typically tranlate from words to equations. By asking them to go the other direction, students can focus on the meaning of the equation first.
