Last week, both classes began their pre-fractions units. Fifth graders are reviewing their learning from 4th grade pertaining to factors and multiples. Fourth graders are learning to find factors and multiples and identify numbers as prime and composite.
As a learning resource, all students can use the following sites/videos to review learning from in class. The two sites, LearnZillion and Khan Academy, have videos and other resources for topics in all subjects, so they are just generally good, reliable resources.
Factors:

- https://learnzillion.com/lessons/784-use-divisibility-rules-to-determine-if-a-number-is-a-multiple-of-2-5-or-10
- https://learnzillion.com/lessons/785-find-all-factor-pairs-of-a-number-using-a-t-chart
- https://www.khanacademy.org/math/cc-fourth-grade-math/cc-4th-fact-mult-topic/cc-4th-factors-multiples/e/factor-pairs
Prime/Composite:

Greatest Common Factor and Least Common Multiple (above grade level standards - go for a 4!):

Games: there are SO many, these I just some I found - and tried haha!
Originally, students were to have a quiz on this subject on Friday, but due to last week's delay and today's snow day, the assessment will most likely be move to next Wednesday.
