Ask how and why

The best test of whether students can get answers right consistently is whether they can explain how they got the answer.

Teacher: How far is it from Durango to Pueblo?

 

Student: Six hundred miles

 

Teacher: How’d you get that?

 

Student: By measuring three inches on the map and adding two hundred plus two hundred plus two hundred.

 

Teacher: How’d you know to use two hundred miles for each inch?               

 

Student: I looked at the scale in the map key.
