We first read "White Rabbit's Color Book" by Alan Baker. I love this book and will use this a lot. It is about this white rabbit that finds 3 tubs of paint and decides to take a dip and mix colors.
We made a red collage starting this red paint...
We also read "Hello, Red Fox" by Eric Carle which is a great book for teaching complementary colors but is too advantage for Hailey. I didn't want to confuse her so we just simple read it instead of point out the different colors on it. Hailey loves foxes and animals.
