Grade 4 - Number
Standard 4.N.6 - Practice multiplication word problems.
Included Skills: Multiplication
Demonstrate an understanding of multiplication (2- or 3-digit by 1-digit) to solve problems by: • using personal strategies for multiplication with and without concrete materials. • using arrays to represent multiplication. • connecting concrete representations to symbolic representations. • estimating products. • applying the distributive property. • Model a given multiplication problem, using the distributive property; e.g., 8 × 365 = (8 × 300) + (8 × 60) + (8 × 5). • Use concrete materials, such as base ten blocks or their pictorial representations, to represent multiplication; and record the process symbolically. • Create and solve a multiplication problem that is limited to 2- or 3-digits by 1-digit, and record the process. • Refine personal strategies to increase their efficiency. • Estimate a product, using a personal strategy; e.g., 2 × 243 is close to or a little more than 2 × 200, or close to or a little less than 2 × 250. • Model and solve a given multiplication problem, using an array, and record the process. • Solve a given multiplication problem, and record the process. • Solve a given problem using the standard/traditional multiplication algorithm.
