Students will be split into groups of 3. Each student will be given a clipboard and a recording sheet. They will be started at a station. They will be instructed to be sure to put their answers next to the question number that is on their task poster. NOT EVERYONE STARTS AT #1. (This is hard for second graders to understand sometimes.)
Students will solve the questions at each task station. They may check their work by scanning the QR code at the bottom of the poster. The answer will pop up on their screen. They may then either revise their work or put a star next to it if they had the correct answer.
Students freely rotate among stations. However, they will have to be patient because no more than one group may be at a station at a time.

Here are the tasks to be displayed:

#1: Circle all the shapes that are quadrilaterals followed by several pictures of shapes.

#2: Tony, Mark, and Frank want to share a pizza. Tony says they will each get half of the pizza. Mark says they will each get a third. Who is right and how do you know?

#3: What shape is this? Followed by a drawing of a hexagon.

#4: Dillon says all rectangles are squares. Do you agree or disagree with him? Draw a picture or use words to prove your side.

#5: Draw a 2 Dimensional polygon with three sides and three angles.

#6: Partition a rectangle into fourths two different ways.

#7: Can you make a square that has two pieces, but they are not halves? If so, draw it. If not, why not?

#8: Give two real world examples of cubes.

When students begin to finish all 8 questions (usually about 20 minutes), gather as a class and discuss the results. Which questions were most difficult? Was it nice to be able to check your work immediately? Did any of the QR codes make you change your mind?
