Lesson 3.1 Multiply by Tens (CC.4.NBT.5) Lesson 3.2 Estimate Products (CC.4.NBT.5) Lesson 3.3 Area Models and Partial Products (CC.4.NBT.5) Lesson 3.4 Multiply Using Partial Products (CC.4.NBT.5) Lesson 3.5 Multiply with Regrouping (CC.4.NBT.5) Lesson 3.6 Choose a Multiplication Method (CC.4.NBT.5) Lesson 3.7 Problem Solving - Multiply 2-Digit Numbers (CC.4.OA.3) Chapter 3 Standards: Operations and Algebraic Thinking; Number and Operations in Base Ten
Use the four operations with whole numbers to solve problems; CC.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. Use place value understanding and properties of operations to perform multi-digit arithmetic; CC.4.NBT.5 Multiply a whole number up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. |
