I am making some nice laminated math mats and would like to economize (besides the laminate itself, also on the amount of stuff I need to manage/carry around) by doing them double sided. I'm in a new grade level to me (never did math for first-second graders before; I used to do reading with those and math for the upper grades) so I don't yet have a feel for which things go together well, I'm kind of learning as I go. So far I have printed out a hundred chart and a page of ten frames. But I don't think I should just stick them back to back with each other because they're not really used for the same concepts or topics. What would go well with these, and what else should I be making that I haven't thought of yet? If it matters, these will be used mainly in a 1:1 setting with the kids who need extra help. Thanks!
