Jacob's Rainbow

Playing Jacob's Rainbow will help your preschoolers learn basic shapes and colors. Jacob's Rainbow uses a simple, problem-solving approach to teaching preschoolers to recognize circles, squares, and triangles and the primary and secondary colors. A character named Jackovich asks the children to fix the rainbow because it's turned gray. The children won't realize they're learning shapes and colors in the process of adding color back into the gray rainbows. Jacob's Rainbow v.1 does not yet include audio, so preschoolers will need help from someone who can read as they use the app.
