Grade 5 - The Number System

Standard 5.NS.1.5 - Practice multiplication word problems with 3 or more numbers up to 1000.

Included Skills:

Students will be expected to demonstrate, with and without concrete materials, an understanding of multiplication (two-digit by two-digit) to solve problems.
• Performance Indicators
- N05.01 Model the multiplication of two two-digit factors, using concrete and visual representations of the area model, and record the process symbolically.
- N05.02 Illustrate partial products in expanded notation for both factors (e.g., For 36 × 42, determine the partial products for (30 + 6) × (40 + 2).).
- N05.03 Represent both two-digit factors in expanded notation to illustrate the distributive property (e.g., To determine the partial products of 36 × 42, record (30 + 6) × (40 + 2) = 30 × 40 + 30 × 2 + 6 × 40 + 6 × 2 = 1200 + 60 + 240 + 12 = 1512.).
- N05.04 Describe a solution procedure for determining the product of two given two-digit factors, using a pictorial representation such as an area model.
- N05.05 Solve a given multiplication problem in context, using personal strategies, and record the process.
- N05.06 Create and solve multiplication story problems, and record the process symbolically.
- N05.07 Determine the product of two given numbers using a personal strategy and record the process symbolically.
