Grade 4 - Number
Standard 4.N.5 - 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, explaining the results of dividing by 1, solving problems involving division of whole numbers, relating division to multiplication. • Solve a division problem without a remainder using arrays or base ten materials. • Solve a division problem with a remainder using arrays or base ten materials. • Solve a division problem using a personal strategy and record the process symbolically. • Create and solve a word problem involving a 1- or 2-digit dividend (the number being divided into). • Estimate a quotient using a personal strategy (e.g., 86 ÷ 4 is close to 80 ÷ 4 or close to 80 ÷ 5). • Explain the property for determining the answer when dividing numbers by one. • Explain, using examples, the relationship between division and multiplication.
