Grade 4 - Number

Standard 4.N.5 - Estimate which sign makes the inequality true by first rounding the division problem numbers to the nearest numbers that divide evenly.

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, 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.
