A Brag Book (Photo Book) I got this one at the Dollar Tree. Some flash cards also from the Dollar Tree. Also Vis-A-Vis wet erase markers and a small package of wet wipes, one can do math facts just about anywhere!! This one I chose to mix addition and subtraction so my Granddaughter will learn to watch signs. She also has a book of subtraction only and addition only. She likes doing this in the car. Multiplication Cards can be used for older kids. Dry erase and a sock will work too.
DIY toy grocery store for around $10! 5 dollar tree bins hot glued together, foam board top trimmed to fit and hot glued, cash register on sale at Walgreens ($5), a hook, and some craft bags! We already had the plastic food.
