Math Unit 2: Factors, Multiples, Prime & Composite

Math Unit 2: Factors, Multiples, Prime & Composite

Author: Cameron Clark
  1. I can define prime and composite numbers.
  2. I can determine and prove if a number is prime or composite.
  3. I can identify all factor pairs for any given number 1-100.
  4. I can recognize that a whole number is a multiple of each of its factors.
  5. I can decide if any whole number (1-100) is a multiple of any other one digit number.
  6. I can identify a number or shape pattern.
  7. I can create a number or shape pattern that follows a specific rule.
  8. I can look at a pattern, determine the rule, and identify other characteristics of the pattern (always even or odd, alternates between odd and even, etc.).

In this unit students develop understanding of multiples and factors, applying their understanding of multiplication from the previous year. This understanding lays a strong foundation for generalizing strategies learned in previous grades to develop, discuss, and use efficient, accurate, and generalizable computational strategies involving multi-digit numbers. These concepts and the terms "prime" and "composite" are new to Grade 4, so they are introduced early in the year to give students ample time to develop and apply this understanding.

What is this?

Below you will find links and resources for our Math Unit 1.

  • LearnZillion is a video resource that has student-friendly videos of the concepts we are covering in class. They provide visual models and examples.
  • ShowMe are videos that I have made using the vocabulary we used in the classroom. You can watch these to see how I teach the concepts.
  • IXL is a website that students can use to practice the math concepts. Students each have their own login and password for the IXL site. Their login is their computer login followed by @rdes. (Example: cclark@rdes) Their password is the same password they use to login to the computers at school.
