Hi Pam, so much fun!
You're lucky to live in a part of the country where you CAN grow enough early produce to do a market!
I'd consider reaching out to the parents' group (if there is one) and the school program coordinator to find one date in the spring where an after-school pick up might work, and have both promote it. This brings up questions like: is there cold storage available in the school so that you can harvest all week and then bring the produce out to the stand? You'll of course want to source ecofriendly produce bags. Check to see if the school (or a parent) has a Square or other remote card-reader - taking cash is difficult (as many folks don't carry it), but, imho you'll still want a cash box and change available.
My main question is: have you created lesson plans around the market project? It's a great opportunity for students to learn a very many things. Consider creating learning objectives on: public speaking (how will students talk about the garden and produce), Math (how to set prices and determine break-even; basic addition and subtraction in handling the money and in stocking the table), STEM (all the gardening issues of soil health, fertilizing, what happens to plants once they are cut, etc), Art/Design (how will the stand look) - so many things!
