For awhile now I have been following Runde's Room: Math Journal Sundays.
I LOVE LOVE LOVE Jen's ideas on math journals and foldables. My goal is to use math journals more in the future. Right now my kids have J.A.M journals or Journal About Math. Just a plain spiral notebook with the JAM label on the front. I love making kids guess what the JAM stands for. A lot of kids get close but I can typically stump them on this one.
I use the JAM now as a way for kids to take notes. Plain, boring notes. I want to make them more interactive using foldables and such. I highly suggest you head on over to Math Journal Sundays to get some great ideas on how to use interactive hands-on math journals. Thanks for the ideas Jen!
