Multiplication Series: Number Arrays

This one-page article describes and illustrates how arrays can be used to represent many number concepts, including building multiplication facts, commutativity, parity (odd/even), and exploring factors, prime numbers, and square numbers.

This resource is included in the following PD Collection(s):
Rectangular ArraysThis collection includes resources for introducing both discrete (separate objects) and continuous (area model) arrays to young learners. The resources provide suggestions about how to use arrays to introduce students to ways of organizing collections of objects, to repeated addition, to multiplication, to factorization, and to area. Helping young learners to develop a deep understanding of the characteristics of arrays will provide the foundations they will use when learning about multiplication and division, area measurement, and fractions.
CCSS Practice Standard 4This collection supports teachers as they integrate Practice Standard 4 into their classroom routines. In these articles, videos, and lesson studies, teachers will see strategies that help guide students to use concrete, pictorial, and symbolic representations to describe mathematical situations in everyday life. Additional resources for immediate use in the classroom can be found in a companion classroom collection.
