Grade 4 - Number

Standard 4.N.7 - Practice divisibility rules with numbers up to 10,000,000.

Included Skills:

Demonstrate an understanding of division (1-digit divisor and up to 2-digit dividend) to solve problems by:
• using personal strategies for dividing with and without concrete materials.
• estimating quotients.
• relating division to multiplication.
• Solve a given division problem without a remainder, using arrays or base ten materials, and connect this process to the symbolic representation.
• Solve a given division problem with a remainder, using arrays or base ten materials, and connect this process to the symbolic representation.
• Solve a given division problem, using a personal strategy, and record the process.
• Refine personal strategies to increase their efficiency.
• Create and solve a division problem involving a 1- or 2-digit dividend, and record the process.
• Estimate a quotient, using a personal strategy; e.g., 86 ÷ 4 is close to 80 ÷ 4 or close to 80 ÷ 5.
• Solve a given division problem by relating division to multiplication; e.g., for 100 ÷ 4, we know that 4 × 25 = 100, so 100 ÷ 4 = 25.
• Solve a given problem using the standard/traditional division algorithm.
