I want to have some easy to use (year round) type math centers to use everyday during the last 20 minutes of our math class. Ones that I can make on my own are best, but I don’t mind spending a little bit of money, especially if you include supplies. I don’t have much so far, but what I do have is: flashcards (they seem to love those!), and using playing cards to make up equations, etc. Any suggestions you have are greatly accepted, especially if they are ones that can be used at the beginning of the year and for all different abilities. (It’ll be a few weeks after the start of school before we get them put into their ability groups) Thank you so much in advance! Also- Any cheap manipulatives you can think of?
