65.  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.

66.  Mr. Garvey is working on finding the volume of pyramids with his seventh-grade math class.  His students have trouble distinguishing between the altitude of a face of the pyramid and the altitude of the pyramid itself.  He then makes a pyramid out of cardboard, sticks a toothpick down the middle, and says, “Now this is the altitude of the pyramid itself.”  They then deal effectively with the problem.  Based on this information, the best description of the stage of thinking Mr. Garvey’s students are using  is:

a.preoperational, since they cannot correctly perceive the difference between the two altitudes.

b.concrete operational, since they can solve the problem with concrete materials.

c.formal operational, since they are in the seventh grade, which typically makes them 12 years old.

d.formal operational, since finding volumes requires the use of symbols, which is abstract.

Use the following information for items 67 and 68.

Mrs. Green teaches an eighth-grade physical science class with students of average to above-average ability.  The students are having a difficult time understanding the idea that ice melts at 32 degrees Fahrenheit and water freezes at the same temperature.  They can’t understand how a solid and a liquid can be at the same temperature when the material is the same.

Mrs. Green explains, “Heat is required to change ice from the solid state to the liquid state.  The energy is needed to break down the orderly arrangement of the molecules in the ice, even though the molecules don’t move any faster.”

Her students still don’t get it.
