Standard Benchmarks
Benchmark: 4.1.1.1 Multiplication & Division Facts
Demonstrate fluency with multiplication and division facts. Benchmark: 4.1.1.2 Multiply by 10, 100, 1000 Use an understanding of place value to multiply a number by 10, 100 and 1000. Benchmark: 4.1.1.3 Multi-Digit Multiplication Procedures Multiply multi-digit numbers, using efficient and generalizable procedures, based on knowledge of place value, including standard algorithms. Benchmark: 4.1.1.4 Estimate Products & Quotients Estimate products and quotients of multi-digit whole numbers by using rounding, benchmarks and place value to assess the reasonableness of results. For example: 53 × 38 is between 50 × 30 and 60 × 40, or between 1500 and 2400, and 411/73 is between 5 and 6. Benchmark: 4.1.1.5 Real-World & Mathematical Problems Solve multi-step real-world and mathematical problems requiring the use of addition, subtraction and multiplication of multi-digit whole numbers. Use various strategies, including the relationship between operations, the use of technology, and the context of the problem to assess the reasonableness of results. Big Ideas and Essential Understandings
Fourth graders continue work with multiplication
and division by demonstrating mastery of basic multiplication and
division facts. They use basic multiplication facts to support work
with the multiplication of multi-digit numbers. In addition, place
value understanding supports multiplication by 10, 100 and 1000. Fourth
graders solve multi-step problems involving multiplication, addition and
subtraction. They divide multi-digit numbers by one- and two-digit
numbers in problem solving situations. They solve these division
problems using a variety of strategies including
