Product Description
Build your students’ understanding of factors and multiple relationships with this set of fall-themed task cards. The 32 cards in this set focus on factors of numbers through 50 and multiples of numbers through 12. Support your students’ performance with the included reference sheet, and then assess their understanding with the two assessment activities. Your kids will gobble up these task cards and ask for seconds!

Common Core State Standards for Mathematics addressed:
Operations & Algebraic Thinking (4.OA)
Gain familiarity with factors and multiples.
• 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. (4.OA.4)

Included:
• full-page graphic reference sheet
• 32 task cards
• answer sheets and key
• 2 assessment activities and key

Setting the Stage

The graphic reference sheet is the perfect addition to your students’ math journal. It is an excellent way to review the vocabulary associated with factors and multiples, as well as the relationship between them. Use the sheet as a review of these concepts and an introduction to the task cards. It will be a useful reference as they work on the task cards, as well as throughout your multiplication & division instruction.

Practicing the Concept

The 32 cards feature a variety of question types to help build your students’ flexibility when thinking about factor and multiple relationships. Some of the cards have one answer, and others have more than one answer. The cards whose questions have more than one answer are worded to indicate that the students should select more than answer (e.g., “Choose all that apply.”) A number of the cards have questions that are somewhat open-ended, asking students to identify any number (or a set of numbers) that meets specific criteria; for these, the students’ answers will vary, and the answer key identifies some of the possible numbers that a student might write as his or her answer.

The questions on the first sixteen cards focus on the factors of numbers 1 through 25, while cards 17-32 feature questions that relate to numbers from 1 through 50. I designed the cards this way to more easily differentiate for student need. You might have your whole class work on the first half of the set (1-16) in one class period, and the second half (17-32) once they are more proficient with factors and multiples. You might also assign cards 1-16 to your students who are building their proficiency with factors and multiples and have your more advanced students work on cards 17-32.

Assessing Understanding

The two provided assessment activities can be used to evaluate student understanding of factors and multiples. These activities are formatted similarly, and have similar types of questions, though the numbers on each are different. I designed them this way so they could be easily used as a pre/post assessment. However, you can use these activity pages in a variety of ways – guided practice, paired work, homework, center assignments, or any other purpose that fits your teaching style or classroom routines.

If you find these task cards useful, I have many other sets of math and ELA-related task cards and printables available in my store. For more practice with factors and related concepts, please check out the other related resources I offer–
