Task Problem Tuesday

Where did the past year go? Seriously...I don't even know where it went. Life was crazy at home, crazy at school, and the first thing to fall off my radar was this blog.  But I'm back and I'm looking forward to a less hectic year. I've planned out a blog schedule for the upcoming year and I'm excited to share some things that I've been working on. I also have some book reviews to finish up and some books to give away. So stay tuned. But for now,  I'm going to get my groove back by jumping right into another Task Problem Tuesday.

This is one of my favorite tasks for coordinate graphing. I use it as an introduction to coordinate graphs, input/output tables, and linear equations with my fifth graders.  I originally wrote it during a measurement and data class for a state math endorsement. I've used it in fifth, a friend of mine used it with fourth and with a little adjustment and maybe a little extra direction, I think you can have fun in third with it too. It's a pretty flexible task. If you have already introduced these topics, this task would also work as a great practice task or an assessment task.

Now get out some graph paper, rulers, colored pencils and get ready for some fun.

After we talk about the story, I give them the number of cans each student brings in. This is a good place to differentiate the task. Change up the numbers to make it easier for younger students. The numbers included in my problem have students starting with a set number of cans and then increasing daily. You can have everyone start with zero to make it easier. You can also limit your problem to two students instead of four.

Depending on your class, you may want to give one task at a time or you may want to display all five of these tasks. If your class likes a challenge, give all the tasks and let them get started.

 This was the best table anyone created.  Once it was finished, I had this student share her table and explain how it was organized. She did a great job of explaining an input/output table, I just had to give them the correct math terms. Most other students were still finishing their tables and some adjusted and used this student's ideas.

Getting it on a graph was a little harder. I had a few try to use a bar graph and line graph. It was really helpful when someone came up with something resembling a coordinate graph. I showed the class and we started talking about what others were doing. The discussion we had helped those who were trying coordinate graphs to perfect their efforts and it helped those trying other things to move toward coordinate graphs. 

Here are what a few others looked like after our discussion.

Task 3 was a question that most students thought was easy to answer. But we dug a little deeper into the mathematical ideas of slope and equations that work for all number of days in our discussion. A few students were able to write equations with variables that worked for all days and we called it a day. My students loved this task and I think yours will too.
