This collection of 6 lessons (58 pages) introduces principles of Ratios required by common core standards in a manner that is aligned with the Montessori Method. Once concepts are introduced and practiced concretely, students can then apply those concepts to real-life experiences, reasoning out the process, rule, or algorithm. Each lesson has a Follow-up activity and a Control of Error.
