__Materials:__different colored and lengths of math rods and graph paper.

__What we did:__The girls created a bar graph by drawing a horizontal line across the bottom portion of their graph paper, and a vertical line along the left side of the graph paper. They had to leave enough room to write the data information. Then they lined up the rods vertically along that line. Then they determined what they wanted their data to be and wrote it on their graph. One daughter taped her bars on so she could lift the paper.

__Broken-Line Graph____What we did:__The girls placed their chocolate chips at different points on their graph. Then they connected them with the toothpicks. They could have simply connected them by drawing a line with a pencil. They also chose what their data would be and included it. Then they got to eat the chocolate chips.

__Pictograph____What we did:__The girls were given a sticker sheet with a variety of stickers. They put the same kind of stickers in a row on the graph paper. Because there was a different number of each kind of sticker, the length of each row was different.

__Stem and Leaf Plot____Materials:__a "stem" and "leaf" cut out of green paper, dice, and markers

__What we did:__After learning how to make a stem and leaf plot, the girls rolled two dice to get a two-digit number. They wrote the number down, and then did it five more times. Then they wrote all the tens digits on the green stem. Then they glued the leaf to the stem in such a way that they could write the ones on the leaf in the way that you do with a stem and leaf plot on paper.

__What we did:__The girls used a ruler to make and label a number line by tens from 0-100. Then we learned where to place dots when making this kind of plot. You are dividing a list of numbers in four parts. You first have to line them up from smallest to largest. Then you make a dot below the number line under the smallest of those numbers and another one below the largest one. Then you have to make another dot exactly under the middle point, which you find by finding the median of the numbers. Then you put a dot below the middle point between the middle dot and the dots on each end. To do that you have to find the median number between the numbers represented by those dots. After the girls did that, then they learned how to make a "whisker" by connecting the two dots on each side, and how to draw a box around the dot in the middle. Then I let them decorate them by adding more whiskers and making a face in the box.

__Materials:__frosting decorator dots and paper

__What we did:__The girls scattered a few decorator frosting dots on graph paper to represent the scattered dots in a scatter plot. Then we talked about what kind of data might be represented on a scatter plot. Then the girls got to eat the decorator dots.

__Circle Graph____Materials:__White 4" paper circles, Pie-shaped pieces of different colored paper cut from 4" circles
