Snow Balls |

Give each student a sheet of scrap paper. I keep a box of paper that is clean on one side in my classroom for random activities like this. Yes, each student will have to investigate what is on the back of their sheet of paper. Comparisons will take place. Some students will try to increase their social standing among their peers based on the fact that the back of their page is cooler than that of the other students.

Project 10 equations on the Smart Board. Tell each student to pick an equation and write it on their sheet of paper. Repeatedly remind them that they are only writing the equation, not solving it. Expect to have at least one student solve the equation even though you asked them not to.

Next, ask each student to crumple their paper into a ball. Prepare yourself for looks of disbelief. Some students will literally not want to do this step. They will try to daintily fold their paper. Reassure them that it is okay to crumple the paper.

Set the Smart Board timer for 10-15 seconds. Allow the students to have a snowball fight.

When the timer goes off, the snowball fight must end. Each student picks up a snowball and opens it.

Tell the students that their job is to solve the equation. However, some students should make a mistake on purpose while solving the equation. Don't tell anybody you're going to make a mistake. Just do it.

After students have correctly or incorrectly solved their equations, have the students crumple their paper again.

10 second snowball fight.

Each student finds a snowball. If they open it and find the equation they just solved, they must trade papers with another student. Now, each student's job is to look at the work and grade it. Is it correct? Or is there a mistake? If there is a mistake, the student must correct it.

After the grading has been completed, ask students who found a mistake to share the equation (still projected on the board) and what mistake they found. This is a great conversation starter for discussing common mistakes without making students feel like they have been singled out.

The students had a blast. One student asked if we were ever going to do this again. It provided a nice change of pace between our practice problems on the white boards and our quiz. Most importantly, learning took place. Students were engaged. And, we got to have some fun, too.

Example of Snow Ball with Intentional Mistake |

Most students worked the equation out on their own to see if the other student had solved it correctly. |

Example of a Correct Snowball |

Some students were a little harsh in their grading. |

Watch your positive and negative signs! |

I also found this random note on one of the snowballs... |

I love this! |

A. I love this activity. It sounds like a real blast, and finding safe ways to introduce mistakes and have the students find them and fix them is also a big plus.

ReplyDeleteB. After school today, on one of my desks, I saw that a student had written (verbatim): "We are never getting back together." It was pretty bizarre to see that on one of your snow balls as well.

It's a Taylor Swift song

DeleteHa ha. Good to know!

DeleteThis is seriously awesome! I am going to have to put this into place for review as well. :)

ReplyDeleteIt's a Taylor Swift song and I've used it a few times in class. For instance: "we will never, ever ever find a solution. Like ever." I just say it and then they think it's "so cool that a teacher knows that type of music!" Oh middle schoolers.

ReplyDeleteI've used the snowball fight activity and they really like it. With my students I always need to set ground rules and my biggest one is that if they hit a civilian (aka me) they have to sit out of the next round. It helps keep them it fun without getting out of control. I love the idea of making a mistake on purpose and because of the snowball fight, the kids don't know whether it was someone who did it on purpose or someone who tried to do it right. It takes off a lot of the pressure. I'll definitely be using that.

I also find it interesting you're already doing equations. We started mid-August and are going to start writing equations the end of next week and then get into solving them. It's fun to see how different schools move through the curriculum.

I love this idea! Thank you for sharing all your ideas! Your blog is awesome! I just stumbled upon it last night when I was searching for "Algebra 1 Snowball fight". I'm looking forward to following it. I teach Algebra 1 and Geometry in Texas.

ReplyDeleteI have used this type of activity for vocabulary review (one person writes a vocab word and one person writes a definition) or matching graphs to equations. I love the idea of them solving the problem then grading someone's mistake to have a discussion without peer scrutiny. I am going to use this for a quick fun review of solving equations before we get into solving systems of equations with substitution. Thanks! Love all your creative ideas on your blog!

ReplyDeleteYou're very welcome! And, I love the other ideas you shared for using this activity! I'm going to have to try some of these out later this semester.

DeleteThis is hilarious! I am going to have so much fun with this!!!

ReplyDeleteEnjoy!

DeleteI am actually a student that has to teach the class about distance formula and I am going to use this thank you for the great idea
