This is a collection of 40 different hexagonal additional puzzle cards (hence, the title above.) It includes a solution recording sheet, so your students can do them in any order they want. These would be best used for advanced first graders (who want to tackle double digit addition), 2nd graders who are practicing single and double digit addition, and assessing and remediating 3rd graders.
There is also a "do it yourself" sheet where students can make up their own puzzles and share them with their classmates!
Finally, there is a preview of 8 puzzles which use the same format to have students use deductive reasoning ("if this is true, then this must be true....") to solve the same kinds of problems.
