I found this Math Reference Sheet many years ago on Ms. Sanchez's class website. Her download is still available. I printed out 25 colored copies and mounted on card stock. On the backside I made a sheet of cut and pasted resources that fit my students' needs like measurement charts, number words, etc. I then laminated the cards. They held up for four years and it is now time to remake them.
If this is too old for your class, there are a variety of sheets available on TPT for free that might fit your needs.
Here are my math tool kits that I will have the children store on their desks. It will become the Math/Science tool kit. I need to come up with a clever name for them. We do not use Everyday Math anymore and will be adopting Go Math.
While looking for her website, I stumbled across her Science Sheet that I will also be making for my students.
