Featuring the picture book How Many? by Christopher Danielson
Explore the beauty of numbers through curiosity and conversation with this PF on the Go kit focused on subtraction using the Counting Up and Counting Back strategies. In How Many? each page presents intriguing photographs from avocado halves to footprints and slices of pizza and invites families to wonder, “How many?” There’s no single right answer, just endless possibilities for noticing, comparing, and reasoning together. These fun, open-ended questions naturally lead to deep thinking as children decide what to count and how quantities relate. Families then play Target Zero and All the Chips, exciting games that bring the concept of subtraction to life, while the “Talk About It” activities spark reflection on strategies, patterns, and everyday math moments. Together, these experiences help children see subtraction not just as taking away, but as comparing and exploring relationships between numbers.
