About Parker Parker is Paige and Paxton’s cousin. He’s so cool, and he loves math to boot. He’s 6 years old—correction: 6 and a half! That’s one of the reasons Parker loves math. He loves to be precise. The charismatic Parker is the perfect puzzle to help children develop an appreciation for math as something we count on every day to make sense of the world. We use math to quantify, describe and organize both the concrete and the abstract. But more importantly, math follows a growth mindset: it’s something that we can all be good at. It simply takes practice.
