Among my books, the most widely used one worldwide is ONE IS A SNAIL, TEN IS A CRAB. It’s been adapted for curricula from Australia to Canada. This book is classified as nonfiction although the text is nonfiction and the illustrations are actually fictional. (At least in my experience, crabs do not ride inner tubes.) It introduces a way of thinking that leads, apparently into algebra. It counts from 1-100. So, when I looked at the Common Core, I could see why this book has been embraced by the math community. Here are the standards that I could see immediately related to the book. A trained math teacher would likely find many more.

Yet there are ways math teachers can use lots of children’s books to complete Common Core.

KINDERGARTEN

• CCSS.Math.Content.K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings¹, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
• CCSS.Math.Content.K.OA.A.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
• CCSS.Math.Content.K.OA.A.3 Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).

CCSS.Math.Content.K.CC.A.1 Count to 100 by ones and by tens.

 

GRADE 1

• CCSS.Math.Content.1.NBT.B.2a 10 can be thought of as a bundle of ten ones — called a “ten.”
• CCSS.Math.Content.1.NBT.B.2b The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
• CCSS.Math.Content.1.NBT.B.2c The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

GRADE 2

CCSS.Math.Content.2.OA.A.1 Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.¹

• CCSS.Math.Content.2.NBT.A.1a 100 can be thought of as a bundle of ten tens — called a “hundred.”
