This is the teacher guide and the posters needed for the unit. Included is an answer key for the Essential Questions and the Journal entries. Standards are listed both in Common Core and on the lesson as the Florida MAFS. There are also printables that can be copied and students can cut and paste into their math journals cutting down on your expense of copying. I will be adding to all of my units a take-home reflection homework piece coming before the end of the year. When it is added you will be able to re-download. I know I have found that the students need more time in developing the concepts. Because of this they need extra reflection time so I am going to try giving them a chance to do these reflections at home. :-) As always please let me know if there is a problem so I can correct it and get it back out. Thanks!
