Part 2:
Posing the Problem [Begin:
07:00]
|
The teacher introduces the
main problem for the day by saying, "I will have
everyone use their heads and think a little, okay? Until
now, weve just done calculation practice, but today
you will have to use your heads a little." The
teacher then puts up a poster with the problem: There are
two different types of cakes, one costing 230 yen and the
other, 200 yen. You want to buy 10 cakes, but you
dont want to pay more than 2100 yen. How many of
each type should you buy? The cakes costing 230 yen
"look more delicious." The teacher clarifies
the problem by restating it in several ways, and then
asks the students to work on the problem individually,
for about three minutes, using whatever methods they
would like. |
