Product Description
Helping kids name factors of numbers from one through one hundred is hard work. Grab these handy cards, sheets, and Venn diagram to give your students the conceptual practice they need. These worked in my classroom, and they’ll work in yours too!

What’s Included:
• Factor Cards (numbers two through one hundred) – Students list all factor pairs for each number.
• Factor Sheets – Students list factors for each number (two through one hundred) and tell whether it’s prime or composite.
• Venn Diagram – Students sort numbers 1-100 into prime, composite, and/or square then analyze the patterns.
• Answers – Factors of each number, 2-100, are listed on an answer key. Answers for the Venn diagram are also included.

Using Factor Cards:
• Whole Class Work - Give three or four cards to each student. Ask them to complete the cards and report back to the class.
• Group Work - Give three or four cards to each student in a group. Ask them to complete the cards and support one another.
• Individual Work - Select cards at student’s level for tutoring or independent study.
• Bell Work - Assign a card or sheet of cards at the beginning of math instruction.

Using Factor Sheets:
• Differentiation - Use factor sheets instead of cards for more able students who can work through the numbers with ease.
• Application - After completing the factor cards, challenge all students to work more quickly through the factor sheets.

These cards and sheets work best after students have had some experience with factors and multiples. Prerequisite activities may include drawing arrays, skip counting, and/or learning multiplication facts.
