3.MD.1:
Measurement And Data
Solve Problems Involving Measurement And Estimation Of Intervals Of Time, Liquid Volumes, And Masses Of Objects.
Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
3.NBT.2:
Number And Operations In Base Ten
Use Place Value Understanding And Properties Of Operations To Perform Multi-Digit Arithmetic
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and-or the relationship between addition and subtraction.
3.OA.2:
Operations And Algebraic Thinking
Represent And Solve Problems Involving Multiplication And Division.
Interpret whole-number quotients of whole numbers, e.g., interpret 56 / 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 / 8.
3.OA.8:
Operations And Algebraic Thinking
Solve Problems Involving The Four Operations, And Identify And Explain Patterns In Arithmetic.
Solve two-step word problems using the four operations. 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.3
