I picked up these handy-dandy storage containers at Michaels craft store. They were located on the aisle with the craft beads and such. I think that having the letters and numbers sorted out will make it easier for my students to use them to spell their sight words with and experiment. Michaels has a rewards club. If you sign up, you will get exclusive offers and coupons. These offers are available online or you can download the app in iTunes or on Google Play and let the cashier scan the barcodes. I used my 55% off coupon and my 15% off teacher’s discount on top of that for the clear organizer. I went back a couple of days later and used a 40% off coupon and my teacher’s discount for the pink one. I kicked myself for not going back the next day when the organizers were B1G1 free, but that’s just how much I’d prefer not going shopping with my whole family in tow! I ended up spending less than $5.00 for this clear one and less than $2.00 each for the pink ones, which also come in blue.
