Summary Statement: The study of diagrams and symbols used to model the application of mathematics through problem solving, perseverance, and the use of abstract and quantitative reasoning.Â
In this unit, children make sense of one- and two-step number stories involving all four arithmetic operations. They represent situations with diagrams, arrays, pictures, words, and number models. Through creating, sharing, comparing, and interpreting representations, children improve their problem-solving strategies and further their understanding that problems can be solved in more than one way.
Represent and solve problems involving multiplication and division.
Multiply and divide within 100.
Solve problems involving the four operations, and identify and explain patterns in arithmetic.
Use place value understanding to perform multi-digit arithmetic.
Summary Statement: The study of algorithms through abstract and quantitative reasoning about the structures of place value and equal grouping.
In this unit, children use place value to develop and practice strategies for addition and subtraction of 2- and 3-digit numbers. They represent multiplication using arrays, and use these representations to develop strategies for solving multiplication facts.
Represent and solve problems involving multiplication and division.
Understand properties of multiplication and the relationship between multiplication and division.
Multiply and divide within 100.
Solve problems involving the four operations, and identify and explain patterns in arithmetic.
Use place value understanding to perform multi-digit arithmetic.
Represent and interpret data.
