Create Picture Graphs (Pictographs)
šØ Math class meets Art class! We can create beautiful charts where the data is represented by little smiling faces, stars, or apples.
Concept
A picture graph (Pictograph) is the most fun graph to look at, but you have to be careful when drawing it! šÆ **The Number Key rule:** The most important rule in creating a picture graph is the **KEY**. At the bottom of the graph, it must say "What does 1 picture mean?". * Key: ā = 1 vote. (If 3 kids voted for pizza, you draw 3 stars: āāā). * Key: ā = 2 votes. (Bigger numbers!). (If 4 kids voted for pizza, you only draw 2 stars! āā. 2+2=4!). We usually stick to the easy Key in second grade (1 picture = 1 vote) until you learn your multiplication tables!
Try it
Be the math artist! **Instructions:** Imagine drawing the symbols for the picture graph. Assume the Key is 1 Symbol = 1 Vote! **Table of Votes for Favorite Color:** * Red: 4 votes * Blue: 7 votes * Green: 2 votes * Key: 1 Smiley Face š = 1 vote. **Problem 1:** How many Smiley Faces š should you draw next to the color Red? * Answer: ___ faces. **Problem 2:** How many Smiley Faces š should you draw next to the color Blue? * Answer: ___ faces. **Problem 3:** How many Smiley Faces š should you draw next to the color Green? * Answer: ___ faces. **Problem 4:** If you wanted to add "Yellow: 5 votes", how many faces would you draw? * Answer: ___ faces.
