Commerce in Japan - Math Challenge and Kanji

Before we move on, let's do a few math problems, then briefly work with kanji.

Math Challenge

買(か)い物(もの)の計算(けいさん)：Shopping Math

次(つぎ)の質問(しつもん)を読(よ)んでください。いくらになりますか。

Kanji

Let's review the kanji: 玉. Remember from our review of kanji previously, it's better to learn kanji in words rather than isolating one kanji because they change reading (sounds), depending on how they are used.

**Kanji with Reading Examples**
Kanji	Base Meaning	Example 1	Example 2
玉	たま ball	お年玉おとしだま = New Year's money gift	玉子たまご = egg

The following flash cards will help you learn the proper method for writing these kanji. Please practice, even if just with your finger, to write these new kanji. After practicing with your finger a few times, try to write them in your notebook using the proper strokes.
