Following this discussion, the teacher sent students off to work on a set of multiplication problems. Their work on the problems gave evidence that some of them were applying aspects of the reasoning discussed in the class session. For example, Katherine computed 74times6 by first computing 74times2 and writing the product. Then she doubled the answer to get the solution to 74times4 and added the two products together to get the solution for 74times6 (see fig. 5.29). She was using thinking similar to Malia's, which seemed to involve the distributive property.
