What educators are saying

This was a great resource for my 6th graders! They were able to use this resource to build a stronger understanding of LCM and GCF.
This resource helps students see the difference between GCF & LCM. It's nice to have a note sheet with everything in one place.

Description

Use this Ladder Method Doodle Notes page to introduce or review the different ways the ladder method can be used – to find prime factorization, least common multiple, greatest common factor, and to factor expressions.

Students can then keep these notes in their notebooks and use them as a reference or study tool.

Included in this resource:

  • Doodle Notes page (2 versions):
    • One that’s completely blank, to be filled in
    • One that has the notes in the ladder filled in

  • Notes sheet about using the ladder method for factoring expressions, in case you haven’t used it for that purpose before.
    • You can use this for your information only or share it with students.

  • Answer key
  • Completed Doodle Notes sample page

Tips for Using the Doodle Notes

Encourage students to “color-code” their notes or add pictures or additional notes, etc, to help them remember the concepts.

  • For example, I used pink for the ‘prime’ definition and for the prime numbers I used on the ladder.
  • I used green for the check marks and the work/notes for checking.

Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).
