Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. - **4.NR.2.4**: Solve authentic division problems involving up to 4-digit dividends and 1- digit divisors (including whole number quotients with remainders) using strategies based on place-value understanding, properties of operations, and the relationships between operations. - **4.NR.2.5**: Solve multi-step problems using addition, subtraction, multiplication, and division involving whole numbers. Use mental computation and estimation strategies to justify the reasonableness of solutions. ## Georgia Milestones coverage - Mathematics Grade 4 (EOG). Numerical Reasoning. Using part-whole strategies, solve problems involving addition and subtraction through the hundred-thousands place, as well as multiplication and division of multi-digit whole numbers presented in real-life, mathematical situations. (about 14% of the test; 8 points) ## What mastery looks like Georgia's Achievement Level Descriptors. The levels are cumulative: each includes the ones before it. Proficient is on grade level. - **Beginning**: Given a visual representation, solve problems involving multiplicative comparison. Multiply multi-digit whole numbers (up to 4 digits) by single-digit whole numbers. - **Developing**: Add and subtract multi-digit whole numbers to the hundred-thousands place. Solve multiplicative comparison problems. Multiply multi-digit whole numbers (2 digits by 2 digits). Divide multi-digit whole numbers (up to 4-digit dividends) by single-digit whole numbers (1-digit divisors). - **Proficient**: Add and subtract multi-digit whole numbers within 100,000 to solve real-life mathematical problems. Interpret and solve real-life mathematical problems involving multiplicative comparison using an expression or visual representation. Multiply multi-digit whole numbers (up to 4 digits) by single-digit numbers or multiply 2 two-digit whole numbers to solve real-life mathematical problems. Divide multi-digit whole numbers (up to 4-digit dividends) by single-digit whole numbers (1-digit divisors) to solve real-life mathematical problems. Justify the reasonableness of solutions using mental computation and estimation strategies. - **Distinguished**: Use multiple operations (addition, subtraction, multiplication, and division) with multi-digit whole numbers to solve real-life multi-step mathematical problems. ## The same standard across grades - Kindergarten, K.NR.2: Use count sequences within 100 to count forward and backward in sequence. https://georgiahomeroom.org/standards/code/K.NR.2.md - Grade 1, 1.NR.2: Explain the relationship between addition and subtraction and apply the properties of operations to solve real-life addition and subtraction problems within 20. https://georgiahomeroom.org/standards/code/1.NR.2.md - Grade 2, 2.NR.2: Apply multiple part-whole strategies, properties of operations and place value understanding to solve real-life, mathematical problems involving addition and subtraction within 1,000. https://georgiahomeroom.org/standards/code/2.NR.2.md - **Grade 4, 4.NR.2 (this standard)**: Using part-whole strategies, solve problems involving addition and subtraction through the hundred-thousands place, as well as multiplication and division of multi-digit whole numbers presented in real-life, mathematical situations. - Grade 5, 5.NR.2: Multiply and divide multi-digit whole numbers to solve relevant, mathematical problems. https://georgiahomeroom.org/standards/code/5.NR.2.md - Grade 6, 6.NR.2: Apply operations with whole numbers, fractions and decimals within relevant applications. https://georgiahomeroom.org/standards/code/6.NR.2.md - Grade 8, 8.NR.2: Solve problems involving radicals and integer exponents including relevant application situations; apply place value understanding with scientific notation and use scientific notation to explain real phenomena. https://georgiahomeroom.org/standards/code/8.NR.2.md Source: Georgia Standards of Excellence, published by the Georgia Department of Education at case.georgiastandards.org.
