Operations And Algebraic Thinking
sub_category:
Use The Four Operations With Whole Numbers To Solve Problems.
state_standard:
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.

## Common Core Instruction: Solving Addition and Subtraction Word Problems with Tape Diagrams

This Mathematics Common Core lesson features fourth grade students from Fort Ann Elementary School in Fort Ann, NY. The lesson focuses on Math Standards 4.OA.3 - Solve multi step 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 AND 4.NBT.4 - Fluently add and subtract multi-digit whole numbers using the standard algorithm. Students work in teams to explore and solve subtraction problems modeling with a tape diagram.

## Grade 4 Mathematics Module 7

Grade 4 Module 7: Exploring Measurement with Multiplication

In this 20-day module, students build their competencies in measurement as they relate multiplication to the conversion of measurement units.  Throughout the module, students will explore multiple strategies for solving measurement problems involving unit conversion.

## Grade 4 Mathematics Module 3

Grade 4 Module 3: Multi-Digit Multiplication and Division

In this 43-day module, students use place value understanding and visual representations to solve multiplication and division problems with multi-digit numbers. As a key area of focus for Grade 4, this module moves slowly but comprehensively to develop students’ ability to reason about the methods and models chosen to solve problems with multi-digit factors and dividends.
