sales and how much money they will make.
Grade Level for recommended use: 3rd-5th grade
TEKS: (b) Knowledge and skills.

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.

Ask students for different ways to keep track of information and write their
answers on the board.
Explain that graphs are a quick and easy way for people to see information. Show
different types of graph and label them.
Read the book Lemonade For Sale.
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.
