Thank you for making their morning!
We are at that point in the year where student artwork will be making its way home — yay! Take a few minutes to enjoy what they made. You’ll see a lot of creativity and effort in their pieces. Check out this blurb... "How to Talk to Kids About Their Art" with simple prompts you can ...use. It’s great for starting positive conversations and helping your child feel proud about their creations. Want a quick idea? Host a little at-home "art show" by hanging the pieces, asking a question or two from the sheet, and celebrating their effort. Your encouragement really boosts their confidence and love for art & creativity! Thank you for your support! ~Mrs. Gibson
