I was playing around on Hot Coupon World the other day and came across this link. Did you know that you can send unused AND expired coupons to a military bases overseas where they can be used at the commissary? (I didn't.) AAANNND because it's a U.S military base, you pay domestic postage, not international.
Then, I was reading at Blissfully Domestic where Alison has been posting summer tips for kids to keep their writing, math, and reading skills sharp. As a former kindergarten teacher, one skill I really valued when kids came to me in August is do they know how to use scissors.
See where I'm going here? Give you preschooler/kindergartner the coupon pages and teach them where to cut (dotted lines, etc.). They'll get good fine motor practice, be helping Mommy and soldier families, and get some great exposure to environmental print while they're at it. As if that's not enough, you have a great sorting lesson separating food coupons from non-food coupons (the Overseas Coupon Program asks that you do this), and a practical life-skills lesson on addressing and mailing a letter.
