4.OA.4
About the Math
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.

Instructional Tasks
TASKS
These tasks can be used with small group or whole group instruction.
- Using the hundreds chart from the resources page, students will investigate multiples and see what patterns they notice. On the hundreds chart, shade in all of the multiples of 2 that are less than 50. Students can continue this process with the other hundreds charts using multiples of 3, 4, 5 and 6. As students work, look for accurately identified patterns that are made about the chosen number and its multiples. Determine if the students can provide mathematical support for their statements, using the hundreds chart or their own number sense as evidence. Have teams share their insights with the whole group.
- After defining important vocabulary for the lesson (prime, composite, array, factor), students will use colored tiles to create arrays for numbers 1-20 to determine if they are prime or composite. Students should build arrays and record the factors (or the dimensions) used to create the array. Consider using 1-inch graph paper for students to use as a recording sheet.
- What are possible multiples that could go in the Venn Diagram? Place at least three numbers in each section of the Venn.
- Jacob said that all prime numbers have to be odd? Do you agree with him? Justify your answer.
- How are the terms “factors” and “multiples” related? Use examples to support your answer.
- Linda says that 33 is prime because it is odd. Is she correct? Explain why or why not.
- What products could have a factor of 4? How many of those products exist in the numbers 1-100? What are they?
- Name three prime numbers greater than 12? What is the greatest prime number in the number set 1-100?
- Use the digits 0-9 to form five prime numbers.
SLIDE-BASED TASKS
These links are HCPSS created instructional tasks. These tasks are provided in Google slides. These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first (often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.
