Product Description
I created this Triangler Puzzle game for my common core math stations.The focus is on adding rational numbers in decimal form.

It is great for stations as it can be easily differentiated. For a lower level group, exclude the bottom row of the puzzle. I prepare both versions so that I can swap them out as groups are rotating. Laminate the puzzle pages and cut out the puzzle pieces. An answer key is included. I print one to keep on hand while students work. I laminate the included student directions to keep at the station.

My station rotations are in groups of four. I like to use this as a group station. That is, when the group gets to this station, they all work together to assemble the puzzle. The discussions that arise are awesome. You could also have the students work individually or in partner pairs. You would just need to print multiple versions of the puzzle. Doing so on different colored sheets of paper will make it easy to keep in order. I prefer card-stock for the weight and feel, but plain copy paper works, too.
