Grade 4 - The Number System

Standard 4.NS.1.6 - Practice estimating multiplication word problems by first rounding the numbers then multiplying them together.

Included Skills:

Students will be expected to demonstrate an understanding of multiplication (one-, two-, or three-digit by one-digit numerals) 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

Performance Indicators
- N06.01 Model a given multiplication problem, using the distributive property (e.g., 8 × 365 = (8 × 300) + (8 × 60) + (8 × 5)).
- N06.02 Model the multiplication of two given numbers, limited to one-, two-, or three-digit by onedigit numerals, using concrete or visual representations, and record the process symbolically.
- N06.03 Create and solve multiplication story problems, limited to one-, two-, or three-digit by onedigit numerals, and record the process symbolically.
- N06.04 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).
- N06.05 Model and solve a given multiplication problem using an array, and record the process.
- N06.06 Determine the product of two given numbers using a personal strategy, and record the process symbolically.
