2. Reason abstractly and quantitatively. Make sense of quantities and their relationships in problem situations. Contextualize quantities and operations by using images or stories. Decontextualize a given situation and represent it symbolically. Interpret symbols as having meaning, not just as directions to carry out a procedure. Know and flexibly use different properties of operations, numbers, and geometric objects. Fourth grade students use reasoning to analyze relationships between quantities in problems, particularly those involving mental math and estimation. Listen and look for students that exhibit the following behaviors: • identify and understand the quantities in the problem • show and explain how quantities are related (e.g., bar diagram) • translate real-world contexts correctly to numbers, expressions, equations, or concrete or pictorial representations • connect numbers, expressions, equations, or concrete or pictorial representations back to real-world contexts Sentence Frames: • The number __________ represents ___________ in the problem because ____________. • I can represent this problem by using ______________.

Strand: Numbers and Operations in Base Ten Fourth Grade students will use place value understanding and properties of operations to perform multi-digit addition, subtraction, multiplication, and division using a one digit divisor. Standard 4.NBT.4 Fluently add and subtract multi-digit whole numbers using the standard algorithm. Strand: Operations and Algebraic Thinking Use the four operations with whole numbers (addition, subtraction, multiplication, and division) to solve problems. Standard 4.OA.3 Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
