Grade 4 - Number
Standard 4.N.7 - Practice divisibility rules from 1 to 9.
Included Skills: Number Properties, Division
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.
