I have a large block of time for math each day and I am on the look out for new activities to add that will help my students develop number basics. Here are some great freebies:
I found this colorful printable 1-20 Number Train at Kidsparkz.com
These Woodland Animal trains start at different numbers. There are several sets free at Karen Hill's TeachersPayTeachers shop.
This free I Have, Who Has Numbers 1-30 game can be found at Thinking Out Loud on TPT. I love that the kids have to figure out the number they have by looking at ten rods and units.
There is also a free printable 1-30 Number Bingo at Allison Covington's TPT shop.
I love Kinder-craze's free printable interactive number line. I have it in my classroom twice. Once as a reference on the wall for the kids to look at, and again on my metal desk as an interactive center. (I don't have a white board in this classroom to use it on the way Maria does...). Here's the link to her free printable, but be sure to visit her blog to see it in use!
And finally, here's an almost-free Pinterest inspired manipulative I made. I used a 39 cent 5 gallon paint stick from Wal-mart, 25 clothespins, and a Sharpie marker.
I'd love to hear about your math center finds!
