This Common Core aligned Math measurement center is based on the favorite classic Inch By Inch by Leo Lionni, where an inchworm measures different parts of birds until he meets a nightingale. The nightingale threatens to eat him unless the inchworm measures his song. Children will delight in how the inchworm tricks the nightingale and escapes! They will cut out the 1 inch inchworms and manipulate them to measure up the blades of grass. This set includes a color version to use as a Math center and a black & white version that can be used individually! Kids will really measure up!
