Brief Summary: A group of neighborhood kids set up a lemonade stand to help raise
money for a new clubhouse. They use their skills with bar graphs to keep track of their
sales and how much money they will make.
TEKS: (b) Knowledge and skills.
8) Data analysis. The student applies mathematical process standards to solve problems
by collecting, organizing, displaying, and interpreting data. The student is expected to:
(A) summarize a data set with multiple categories using a frequency table, dot plot,
pictograph, or bar graph with scaled intervals; and
(B) solve one- and two-step problems using categorical data represented with a
frequency table, dot plot, pictograph, or bar graph with scaled intervals.

Explain that graphs are a quick and easy way for people to see information. Show
different types of graph and label them.
Ask students to guess what type of graph was used in the book (bar graph) and
what it was keeping track of (#of glasses of lemonade sold).
Have students work in pairs and recreate the graph from the book using their
graph paper and a different color pencil for each day of the week.
Have pairs figure out how many cups total were sold, the average number of cups
sold, and how much they made if they charged \$.25, \$.50, \$1.00.

Once pairs finish this part, have them do the same for the “Second week of sales”
worksheet.
