Grade 4 - Number

Standard 4.N.4 - Practice multiplication word problems with 3 or more numbers up to 100.

Included Skills:

Demonstrate an understanding of multiplication (2- or 3-digit by 1- digit) by: using personal strategies for multiplication, with and without concrete materials, using arrays to represent multiplication, connecting concrete representations to symbolic representations, estimating products, solving problems.
• Model a multiplication problem (concretely or symbolically) 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 a 2- or 3-digit number times a 1-digit number.
• 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 multiplication problem using an array, and record the process.
• Solve a multiplication problem and explain the strategies or processes used.
