## Early Childhood Corner: Storyboards for meaningful patterns

Patterns are an important element of developing children's mathematical reasoning. In elaborating ways in which “instructional programs from prekindergarten through grade 12 should enable all students to understand patterns, relations, and functions” (NCTM 2000, p. 90), the National Council of Teachers of Mathematics specifies that representing and interpreting patterns are skills that kindergartners through second graders should build toward developing a robust understanding of algebra.
