Making Bar Graphs!

 * **Resource:** [|Make a Bar Chart!]
 * Standard: CCLS: 2.MD.10. Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 using information presented in a bar graph.
 * **Objective:** Use a virtual manipulative to create a bar graph
 * **Assessment:**
 * Self: Check with Projector
 * Peer: Check with partner, offer feedback, diagnose problems if necessary
 * Teacher: Walk and Observe
 * **Practice Set:**
 * 1st - Work with your partner to make a bar graph that shows what the members of our class are going to have for lunch. (If necessary, teacher can model how to do this along with the class on a projector, etc.)
 * 2nd - Choose one of the following and work together with your partner:
 * Tonight the Buffalo Sabres play the Boston Bruins. Make a graph that predicts what the final score will be!
 * Make a graph that shows the number of cousins you and your partner have.
 * 3rd - Extra Challenge - [|Snowfall Totals] - Choose at least 3 cities and graph their snowfall totals. (Hint: Count by tens...)
 * **Technological Knowledge Needed**
 * linking from wikispace
 * tabbed browsing
 * knowledge of how the software works
 * **Pedagogical Content Knowledge**
 * one laptop per two children - foster collaboration
 * link to resource from wikispace
 * provide different levels of challenge
 * provided prior to teaching - making a large bar chart as a group
 * things students may struggle with:
 * visualizing quantity
 * keeping organized
 * comparing
 * **Reflection**
 * Good - I did ask them to create a product and they were able to do it. I also am happy with the way I gradually released the responsibility of the task and the software to them, and provided a variety of ways for them to self and peer assess.
 * Bad - I needed to explain and walk them through it the first time more than I expected. The lesson on this page is displayed in a teacher-friendly way, not a kid friendly way.
 * Ugly - There are many more steps to creating a bar graph than I thought! The way they had to determine the specific criteria they were going to graph and organize that information took longer and was more complex than I thought, even for college students.
