Dollar store photo albums... Turn them into flashcard fun! Easy to write and wipe, just insert what you are working on. You could even just insert white paper and have them work on writing sight words, so many ways to use them!
Math tub idea: Get two ice trays from the dollar spot at Target, write 2-digit numbers on white labels for each hole, and kids toss a cube in each tray and add numbers together on recording sheet or whiteboard. They think it's so fun!!
Math Center: I went crazy and made oodles of center activities (inspired by Pinterest) over Thanksgiving break. All the materials were bought at the Dollar Tree :) This one I called "Hot Fact Cakes" ;)
Write a different sight word on each foam square. Then, put them all in a bag. Pair up the students and have them take turns picking a foam square out of the bag. If they can read the sight word that's on the square they get to keep it and add it to their stack. With each word they get their stack grows. If their stack of foam squares topples over they have to put them back in the bag (the stacks usually don't fall over until they get past 10 squares-so make a lot of words for this game!).
I bought lots of the small pocket charts at Target this summer. I decided to use them in my guided reading area. I have one pocket chart with our current reading strategy, the others with reading vocabulary, reading fix up strategies and our guided reading information. (I purchased the Reading Vocabulary words from Kim Adsit (Literacy Vocabulary Packet and Word Wall) at Teachers Pay Teachers)
