Students will solve each problem and choose the snowball with the correct answer on it. There are 24 problems to work with. They can write it on the recording sheet that is provided. Then they can use a QR Code Reader to check their answer if that is a tool that is available to you. (Ipads, Iphones, or other tablet that have the capability to scan) If you can not use a QR Reader, your students can still complete these problems. They can use the provided answer key to do that.
