Factors of 100 – Patterns with Arrays, Factors and Multiples Unit 4.OA.B.4

Factors of 100 is a week-long unit that creates a natural bridge from building arrays to establishing patterns with factors and multiples on a 100s table. Students are motivated to find all the factor pairs, as they self-check their work and make corrections, all the while noticing patterns within the table. It's a nice lead-in to division and fractions.

There is built-in homework, computation practice, class discussions, and a final written assessment. It's a good beginning of the year reminder or pre-assessment for 5th & 6th grades, as they articulate the patterns found in the tables.

The unit includes arrays, factor pairs, proper factors, square numbers, prime, composite, abundant, deficient & perfect numbers, as well as multiples.

You will find extensive teaching notes, answer keys, and ideas for uses beyond the initial unit, such as LCM and GCF.

I've used it annually, at the beginning of the year, with my 6th graders as a refresher/reminder of all the pattern connections and vocabulary. I've also used parts of it with high 3rd graders who enjoyed the challenge of figuring out the patterns. The final product makes a year-long reference tool.
