Grade 4 - The Number System

Standard 4.NS.1.7 - Practice divisibility rules with numbers up to 10,000,000.

Included Skills:

Students will be expected to demonstrate an understanding of division (one-digit divisor and up to two-digit dividend) to solve problems by
• using personal strategies for dividing, with and without concrete materials
• estimating quotients
• relating division to multiplication

• Performance Indicators
- N07.01 Model the division of two given numbers without a remainder, limited to a one-digit divisor and up to a two-digit dividend, using concrete or visual representations, and record the process pictorially and symbolically.
- N07.02 Model the division of two given numbers with a remainder, limited to a one-digit divisor and up to a two-digit dividend, using concrete or visual representations, and record the process pictorially and symbolically. (It is not intended that remainders be expressed as decimals or fractions.)
- N07.03 Solve a given division problem, using a personal strategy, and record the process symbolically.
- N07.04 Create and solve division word problems involving a one- or two-digit dividend, and record the process pictorially and symbolically.
- N07.05 Estimate a quotient using a personal strategy (e.g., 86 ÷ 4 is close to 80 ÷ 4 or close to 80 ÷ 5).
- N07.06 Solve a given division problem by relating division to multiplication (e.g., for 80 ÷ 4, we know that 4 × 20 = 80, so 80 ÷ 4 = 20).
