4.OA.4 - About the Math, Learning Targets, and Rigor

Grade 4 Multiplication and Division

4.OA.4

Full Standard 

Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite.

Learning Targets

  • Find factor pairs of any number between 1 and 100.
  • Find multiples of a number (multiples up to 100).
  • Determine if a number is prime or composite.

 

About the Math

A factor is a number that is multiplied by another number to yield a product. Two and eight are factors of sixteen. A multiple is the product of a whole number and any other whole number. Sixteen is a multiple of eight

  • Find factor pairs of any number between 1 and 100.

1, 3, 7, and 21 are factor pairs of 21. Students find factor pairs of numbers to 100. Students should use basic fact recall and number sense to identify factor pairs. Factoring procedures should be avoided. Explicit instruction of divisibility rules is not appropriate, however student discovery of these rules could be an enrichment within this standard for students who show proficiency with factors, multiples, and prime/composite numbers. 

  • Find multiples of a number (multiples up to 100).

24 is a multiple of 1, 2, 3, 4, 6, 8, 12, and 24. Students determine if a number is a multiple of another number. 

  • Determine if a number is prime or composite.

Sixteen is a multiple of eight. A prime number has two unique factors. The number one is considered to be neither prime nor composite. A composite number has more than 2 factors; composite numbers can be represented by at least two unique rectangular arrays.  

Essential vocabulary for this standard includes factor, factor pairs, multiple, prime number, and composite number.
