Barrato Collins
@barratocollins
Math education content creator and instructional designer focused on accessible, accurate learning.
United StatesWhat I'm looking for
I build student-friendly math lessons, teacher guides, and assessments for diverse learners, from autism-informed instruction to U.S.-based classroom materials. I specialize in translating math concepts into clear, well-structured learning experiences.
In my current remote roles, I develop chapter and course elements for Algebra II topics, including initial evaluation, lessons, and chapter tests, as well as teacher guide support. I also perform alignment and gap analysis using a large language model to strengthen course lists and lesson coherence.
Previously, I served as a Math Instructional Designer and Math Curriculum Writer, modifying AI-generated lesson content for conciseness, relevance, and student-friendliness, then final-editing and providing feedback for a U.S.-based audience. I created and revised materials such as curriculum pacing guides, facilitation tips, review materials, intervention/practice resources, and storyboard content for Algebra I learning and support videos.
My background also includes tutoring and grading work, including math instruction for a student with dyslexia and online grading/assistant support for virtual summer camps. Earlier, I authored and reviewed calculus content for an online product using Sapling Learning’s Authoring Management System (AMS), maintaining style guidelines, brand voice, and error-specific feedback by anticipating misconceptions.
