Standard 5.N.5 - Practice multiplication word problems with 3 or more numbers up to 1000.

Included Skills:

Demonstrate an understanding of multiplication (2-digit by 2-digit) to solve problems.
Achievement Indicators
Students who have achieved this outcome(s) should be able to:
- Illustrate partial products in expanded notation for both factors, e.g., for 36 × 42, determine the partial products for (30 + 6) × (40 + 2).
- Represent both 2-digit factors in expanded notation to illustrate the distributive property, e.g., to determine the partial products of 36 × 42, (30 + 6) × (40 + 2) = (30 × 40) + (30 × 2) + (6 × 40) + (6 × 2) = 1200 + 60 + 240 + 12 = 1512.
- Model the steps for multiplying 2-digit factors using an array and base ten blocks, and record the process symbolically.
- Describe a solution procedure for determining the product of two given 2-digit factors using a pictorial representation, such as an area model.
- Solve a given multiplication problem in context using personal strategies and record the process.
