Lesson 2.1 Multiplication Comparisons (CC.4.OA.1) Lesson 2.2 Comparison Problems (CC.4.OA.2) Lesson 2.3 Multiply 10s, 100s, & 1,000s (CC.4.NBT.5) Lesson 2.4 Estimate Products (CC.4.NBT.5) Lesson 2.5 Multiply Using the Distributive Property (CC.4.NBT.5) Lesson 2.6 Multiply Using Expanded Form (CC.4.NBT.5) Lesson 2.7 Multiply Using Partial Products (CC.4.NBT.5) Lesson 2.8 Multiply Using Mental Math (CC.4.NBT.5) Lesson 2.9 Multistep Multiplication Problems (CC.4.OA.3) Lesson 2.10 Multiply 2-Digit Numbers with Regrouping (CC.4.NBT.5) Lesson 2.11 Multiply 3 & 4-Digit Numbers with Regrouping (CC.4.NBT.5) Lesson 2.12 Solve Multistep Problems Using Equations (CC.4.OA.3) Chapter 2 Standards: Operations and Algebraic Thinking; Number and Operations in Base Ten
Use the four operations with whole numbers to solve problems; CC.4.OA.1 Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5x7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations. Use the four operations with whole numbers to solve problems; CC.4.OA.2 Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison. 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. |
