Do you think that the lesson Miss Moore is trying to teach the children is successful?

Miss Moore is trying to teach the children commercial arithmetic. As they walk along the streets, she talks to them about “the costs of things, their parents’ earnings, and income inequality in the country.” Some way down the streets, she hails a couple of cabs, gets in with one-half of the children in one of the cabs, and hands the narrator a five-dollar bill for her cab. She is supposed to calculate ten percent of the five-dollar bill to give the driver as a tip. However, when they get to their destination, the narrator cannot figure out what the tip amounts to and decides not to give the driver his tip, as “he does not need it as bad as she does.”
Next, they reach Fifth Avenue, and Miss Moore invites them to window-shop at a toy store. All the children look through the windows of the shop at items that they’d like to buy. This part of the trip is successful, as the children like to admire the various objects displayed in the shop window. Miss Moore takes advantage of the situation to encourage the children to look up the costs of their favorite items. One of the children sees a microscope, and Miss Moore explains its use to the children. Another sees a really expensive object whose purpose or function the children do not know. Again, Miss Moore comes forth to explain that the item is a “paperweight that has been made of semi-precious stones fused together under great pressure.” Another sees a really expensive toy sailboat that is going for one thousand one hundred and ninety-five dollars. This totally builds up the children’s interest in the various things sold at the shop and their costs. Even the narrator, who despises Miss Moore and rarely talks to her, is motivated to ask about how much a real boat costs. Miss Moore asks the narrator to research this and to later present her findings to the group. Clearly, Miss Moore has managed to capture the children’s interest. She hopes to sustain it by encouraging individual research on whatever questions may arise. She is teaching the children useful learning skills.
Also, Miss Moore specifically chooses to take the children to the expensive toy shop on Fifth Avenue because she hopes to encourage them to think big. She wants them to understand that there are people who can afford luxurious things such as those sold at the toy shop. She hopes to expose them to the larger world. She hopes to make them realize what she has always stated, that “poor people have to wake up and demand their share of the pie.”
At the end of the trip, most of the children are tired because they have learned a lot. Sugar surprises the narrator by saying that her biggest takeaway from the trip is that most of their families make less annual income than the costs of some of the toys at the toy shop. So clearly, Miss Moore’s lesson on this particular day is a big success.
