Are you looking for a quick painless one day lesson for February? I love these Tinted n' Shaded Hearts with Kindergarten. I started this lesson by reading the book Mix it Up! By Henre Tullet. This was a perfect book to review color mixing and introduce tints and shades, and the kids loved it! For this project the kids used tempera cakes and had a blast mixing all different kids of tints and shades to add designs and patterns to pre-cut out hearts. To add a little extra detail I had the kids use forks and white paint on red paper to create a textured boarder. Quick and painless great results and the kids had a blast talk about a win win!
