Review by David Chien
It tends to use formal sentences, so in real life, you may not see them in your other textbooks until later. But, if you get a good Japanese friend to help show you what the informal sentences look like, you'll have a leg up on the basics.
It repeats the same concept a few times so you get familiar with them: eg. How much are the apples? How much are the bears? How much are the jewels?
