List Of Factors Tables
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
Two pads of seventy five sheets for listing factors, one covering one to fifty and one fifty one to a hundred, printed in black, with control charts included. Factors are the reverse question to multiples and much the harder one: instead of counting up from a number, the child has to test what divides into it. Doing that for every number to a hundred is how prime numbers stop being a definition and become the ones where the list ran out. Cardstock and paper, for ages 6 to 12.
“Free the child's potential, and you will transform him into the world.”
The List of Factors Tables serves as a visual bridge between concrete mathematical materials and abstract number relationships in the elementary classroom.
- Recognition of factor relationships for numbers 1-100
- Understanding of prime and composite numbers through factor analysis
- Development of mental calculation strategies using factor knowledge
- Ability to find common factors between different numbers

These reference sheets honor the child's growing capacity for abstraction by presenting factor relationships in an organized, accessible format that children can consult independently. Each grid on these printed cards reveals the mathematical beauty of how numbers decompose into their factors, allowing children to discover patterns and relationships at their own pace. The tables respect the elementary child's need for intellectual independence by providing a tool they can use without adult intervention when exploring multiplication, division, and prime factorization. Unlike manipulative materials that the child has outgrown, these factor tables meet the 6-12 year old's hunger for knowledge and their developing ability to work with abstract concepts. The clear grid format of each table enables children to make connections between different numbers and their factors, fostering the mathematical reasoning essential for advanced work in multiples, least common multiples, and greatest common factors.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the factor tables in a designated mathematics area where children can easily access them. Ensure good lighting and a flat work surface. Have paper and pencil available for children to record discoveries.
- 1
Introduce the tables by showing how to read the grid format, demonstrating with a familiar number like 12
Let the child discover that 12 appears in multiple locations, revealing its various factor pairs - 2
Invite the child to explore patterns, such as which numbers appear most frequently across all tables
Guide them to notice that 1 appears in every table, while prime numbers appear only twice - 3
Show how to use the tables to find all factors of a given number by locating it throughout the grids
Encourage systematic searching from smallest to largest tables - 4
Demonstrate finding common factors by comparing the factor lists of two different numbers
Use colored pencils to mark common factors visually - 5
Challenge children to identify prime numbers by finding those that appear in only two tables
Create a separate list of discovered primes for reference
