Yellow, Red, Green--GO! is a delightful addition to the Small Talk Books(R) math stories. These stories feature a young child and adult talking and having fun, their playful conversations enriching the child's understanding of how math is part of everyday life. Frequent small talks add up to big learning gains! This story explores patterns, an important early math concept. Helmet on, buckle up, and off they go! As mother and young child bike together through their neighborhood to visit grandma, they see many things. They slow down as the traffic light turns yellow, then stop when it turns red, and then pedal forward when it switches to green, not only talking about what the color of each light means, but also about the pattern the lights make as they repeat. What other patterns will they discover along the way?
