Objective (purpose):

Using the given worksheets, students will be able to graph seven variables on a bar graph.

Introduction:

• Get kids together and explain to them that today they will be graphing! Let them know that graphs are used as a visual representation of a set of data and that today they will be making a bar graph (but there are many other types of graphs).
• Say: “Valentine’s Day is just around the corner and I brought some boxes of SweetheartsÃ‚Â©.” (Show the boxes.) “We will graphically show how many hearts of each color are in these boxes! Then we can see what we can learn from our graphs, for example we will know if all boxes contain the same amount of pink hearts or how many more green hearts than orange hearts those a box have! In the end I will let you eat the candy, but you many NOT eat it until the end of the activity!”
• Review colors to make sure the kids know how to distinguish their hearts. (Use the candy hearts as the examples of different colors.) Then as a class determine how many heart colors are in a box (seven: blue, purple, green, pink, yellow, orange, white.)
• Ask the kids to go and get their pencil, white board, and crayons.

Explanation/Modeling:

• Now do a model graph. Use the board and make a big graph.
• Open one box of heart candy and pour it onto a plate.
• Ask kids to volunteer and come up and count the amount of a certain color of hearts in the plate.
• When they have determined the number graph it! (Maybe also put the number at the top of the bar too!)

Board Graph Example:

### My Box of Sweethearts Candy

3 6 7 6 4 5 6

Blue Purple Pink Green Orange Yellow White

• Once all the colors are graphed, discuss what you know by looking at the graph, like which heart color was there the most off. Then maybe see how many more pink hearts there are than orange.

Method of Explanation:

• Now that the kids have seen how to graph, give each one a plate and a box of SweetheartÃ‚Â© candy.
• Next pass out the worksheet (containing a blank bar graph). Tell them to label their headings on the graph.
• Then inform them that they will be responsible for counting, writing, and graphing the amount of hearts of each color they have.
• Make sure that everyone understands the activity and then let them begin.
• Also, let them know that you will be walking around and they can ask you questions if they are confused.

Learning Activities/Reinforcement and Individual Assessment:

• Walk around and help kids understand the assignment. Offer support and make sure they are following directions.
• For those having problems with graphing, maybe ask them to put the candy in lines by color. Then on their graph, they can draw them one by one.

Closure:

• Once everyone is done, discuss the graphs. Compare the graphs to determine if each box has the same amount of candy.
• Also, see if the same amount of a certain color was found in every box.
• Discuss what was learned when the data is graphed.
• Let them eat the candy now!

Relevancy:

• Making and reading graphs is important in math, but even more in physics and chemistry. It is also valuable for statistical information (that is often seen on television commercials).
• Graphs are also used in hospitals (for example to show the heart rate of a patient).
• Children need to understand that many phenomena’s in the world can be graphed to acquire a better understanding.
• Finally remind them that they now know a fact: no box of SweetheartsÃ‚Â© candy is the same.
