Question 2
Mrs. Wells is teaching her fifth graders to find the volume of rectangular solids using the formula V = l x w x h (length times width times height). They had difficulty with the problems, and they couldn't seem to visualize the boxes when shown pictures of them in their textbooks. According to Piaget, which of the following would be the best solution to this dilemma?
a. Wait until they are developmentally ready to deal with the abstraction in finding volume. (Wait and teach it in the sixth grade.)
b. Show them an empty box, and put cubes in it until it is full to illustrate volume and the cubic dimension.
c. Walk them through several problems taken from their textbooks, being certain that they are successful at each step in the calculation.
d. Give them pictures of boxes to help them better visualize the problem.
