2) Let students share their ideas.

Call on students to report。and the teacher writes on the board based on the students' n。Students may come up with the following different methods:

Method 1:

n。Display: 3.5+3.5+3.5=10.5 (yuan)

XXX: How did you come up with this?

Student: 3.5×3 means adding 3 3.5's。so we can use XXX)

Method 2: Convert to yuan。jiao。and fen to calculate。first calculate the whole yuan。then the whole jiao。and finally add them up。3 yuan×3=9 yuan。5 jiao×3=1 yuan 5 jiao。9 yuan+1 yuan 5 jiao=10 yuan 5 jiao。that is。3.5×3=10.5 (yuan).

Method 3: Regard 3.5 yuan as 35 jiao。then 35 jiao×3=105 jiao=10.5 yuan.
