Number & Operations (Models of Multiplication and Division and number properties) Page 11 Computation & Estimation (CE)/Number Operations 3.2 NUMBERS AND OPERATIONS, ALGEBRA, AND DATA ANALYSIS: Most problems on the CBEST for multiplication and division center around story problems, number lines and sets Represent and apply the concept of multiplication as repeated addition Represent and apply the concept of division as repeated subtraction and forming equal groups Apply models of multiplication (e.g., equal-sized groups, arrays, area models, equal "Jumps" on number lines and hundreds charts ) and division (e.g., repeated subtraction, partitioning and sharing ) to solve problems Apply increasingly sophisticated strategies based on the number properties ((e.g., place value, commutative, associative, distributive, identity, and zero) to solve multiplication and division problems involving basic facts Represent, analyze and extend number patterns using rules that involve multiplication and/or addition ((e.g., Analyze frequency tables, bar graphs, picture graphs and line plots; and use them to solve problems involving addition, subtraction, multiplication and division.
