Once there was a kids’ club that need to be fixed a little
and the members of the club found out that they don't have money in their
piggy bank. So one of them came with the idea of selling lemonade. They were
hoping to sale to sale about 30-40 cup of lemonade every day. They decided each
one would be part of that sale to be succeeded. Some were selling others were making
the lemonade. One of them made a bar graph of days and numbers of cups sale
each day. And they started on Monday they sale 30 cups, Tuesday 40 cups,
Wednesday 56 cups, so their sale is increasing so far. Unfortunately on
Thursday they only sold 24 cups, and it was all because there was a boy play
juggle on the other side. The kids decided to bring the boy by their sale table
and make him juggle the lemonade. As far the did on Friday the sale was over
the top of the bar graph that they made. Now they have enough money to rebuild
their clubhouse.

The author did good job to show graphing and linear function
in both ways increasing and decreasing by having positive and negative slope,
so on Monday, Tuesday and Wednesday the sale was increasing, but on Thursday
deceased then increased again on Friday.
Wow! I wish I had read this book as a child, I would have done so much better in class. ( Just joking) I found your post well written and concise. I would definitely read this book in the future.
ReplyDeletemarwa,
ReplyDeletenice job of explaining the plot of this story. i just want to point out that the data from this story does not imply a linear graph. where is your explanation about whether literature is a good tool for teaching/learning mathematics?
