And the Answer Is ….. QR Math Station

The inspiration for this Math Station came from this post http://mrsjumpsclass.blogspot.com/2011/03/zoo-part-2.html .

I thought the anchor chart/whole group activity could easily be changed into an individual or pair activity for a Problem Solving Math Station.

The station includes a instruction sheet and a series of pages for the students to show their work on. The student picks a student sheet. Across the top it says And the Answer is …………. Followed by a QR code. The student then uses an Ipad 2 or Ipod with a camera to read the secret answer. The student comes up with a word problem that fits the answer. The word problem is neatly written on the paper – and the paper can be illustrated. Finally the student will post the problem on a problem solving bulletin board. For the other students to solve. It might even be picked to be spotlighted on our blog. The posting is the main reason I put the answer a QR code. This way other students can try and solve the problem and give feed back about any difficulties solving the problem. One thing I need to emphasize is that we want people to be able to solve the problems. You don’t “win” if your problem is too difficult to understand. There is a link to the center from the picture below.

Problem Solving – What works for my brain

It was interesting watching my students take their Post Unit test. The test was over three units – Division, geometry, and number lines. It was interesting to watch the students as they selected different problem solving strategies. The manipulatives we had used were on the back table. Students could go pick up a set and take it back to their desk. Other students used their dry erase pens to draw on their desk. When we have rotations today – I’m going to ask them about their thinking. I figured out that on average my students score on improved 28 points from their pretest to their post test.
