Grade 5 - Number

Standard 5.N.3 - Practice division word problems with numbers up to 60.

Included Skills:

Demonstrate, with and without concrete materials, an understanding of division (3-digit by 1-digit) and interpret remainders to solve problems.
• Identify situations in one's life, family, or community in which division might be used and explain the reasoning.
• Model the division process as equal sharing or equal grouping using various models and record the resulting process symbolically.
• Explain concretely, pictorially, or orally why division by zero is not possible or undefined (e.g., 8 ÷ 0 is undefined or not possible to determine).
• Generalize, relate, and apply concrete, pictorial, and symbolic strategies for dividing 3-digit whole numbers by 1-digit whole numbers.
• Justify the choice of what to do with a remainder for a quotient depending upon the situation:
- disregard the remainder (e.g., dividing 22 books among 4 students)
- round up the quotient (e.g., the number of five passenger cars required to transport 13 people)
- express remainders as fractions (e.g., five apples shared by two people)
- express remainders as decimals (e.g., measurement and money).
• Solve a division problem that is relevant to self, family, or community using personal strategies and record the process symbolically.
• Recall the division facts to a dividend of 81 including in problem-solving situations.
