Math Routines Cluster 1: Understanding Equal Groups
Standards NC.3.OA.1 NC.3.OA.2 NC.3.OA.3 NC.3.OA.9 For products of whole numbers with two factors up to and including 10: Interpret the factors as representing the number of equal groups and the number of objects in each group. Illustrate and explain strategies including arrays, repeated addition, decomposing a factor, and applying the commutative and associative properties. For whole-number quotients of whole numbers with a one-digit divisor and a one- digit quotient: Interpret the divisor and quotient in a division equation as representing the number of equal groups and the number of objects in each group. Illustrate and explain strategies including arrays, repeated addition or subtraction, and decomposing a factor. Represent, interpret, and solve one-step problems involving multiplication and division. Solve multiplication word problems with factors up to and including 10. Represent the problem using arrays, pictures, and/or equations with a symbol for the unknown number to represent the problem. Solve division word problems with a divisor and quotient up to and including 10. Represent the problem using arrays, pictures, repeated subtraction and/or equations with a symbol for the unknown number to represent the problem. Interpret patterns of multiplication on a hundreds board and/or multiplication table.
