1 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. 3.2.1Represent and apply the concept of multiplication as repeated addition. 3.2.2Represent and apply the concept of division as repeated subtraction and forming equal groups. 3.2.3Apply 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. 3.2.4 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. 3.2.6 Represent, analyze and extend number patterns using rules that involve multiplication and/or addition ((e.g., 3.2.7 Analyze frequency tables, bar graphs, picture graphs and line plots; and use them to solve problems involving addition, subtraction, multiplication and division. Grade 3 MATH: Oregon Department of Education Standards for Practice or Progress Monitoring. OAKS testing format These problems are presented in an OAKS testing format. A passing grade is 80% This booklet will focus on the items in This booklet will focus on ONLY the items in Bold Black [3.2.4] below table. In 2011-2012 these standards will be added to the OAKS assessments. 3.2.5 Apply the inverse relationship between multiplication and division (e.g.,and the relationship between multiples and factors Book #7 This booklet will focus on ONLY the items in Bold Black [3.2.4] Teachers: To assure that the above standards are understood, always remind, ask and show your students: 3.2.4 1.Place value determines 10, 100, 1000, etc… 2.Know multiplication and addition commutative, associative, distributive, identity and zero properties to solve basic facts. Teacher Information... Teacher Information... This booklet does not cover the core standards that will be tested in 2011-2012. 3.2.4Apply 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. The test samples and strand data for this booklet can be found on the Oregon State Departments of Education web site. The use of this booklet was designed for the Hillsboro School District based on HSD Power Standards along with the ODE strand categories. This booklet is paid for and furnished to teachers for instruction by the HSD.
