Overview of Explode the Code

For a fun, but comprehensive mastery-based phonetics curriculum that is tailored to individual students, we recommend Explode the Code Online. Explode the Code Online is a mastery-based curriculum using multi-sensory, research-based and teacher-tested methods for direct, systematic phonics instruction. It was based on the Orton-Gillingham approach to reading, while also using research based techniques and teacher input. Explode the Code Online incorporates an abundance of practice and reinforcement opportunities for greater retention and encourages the development of comprehension skills through reading in context. Parents love the continual built-in assessments, plug and play capabilities, high level of student enjoyment and results. Some families feel that Explode the Code Online focuses more on speed than accuracy, uses some ambiguous pictures, relies on typing skills, and doesn't discriminate between vowel and consonant errors. Some parents also incorporate the Explode the Code workbooks as a supplement to this program.

Grades: PK-4th

Cost: An annual subscription to the online program costs $65 for the first student, with a slightly reduced rate for additional students.

Manisha Snoyer (co-founder of Modulo)

For the last 20 years, I’ve taught over 2000 children in 3 countries (of all socio-economic backgrounds). I pioneered an English language program in a conflict region in the Middle East. I’ve worked as a bilingual public school teacher at some of the highest and lowest performing public schools and in all five boroughs of NYC. I’ve tutored 18 subjects in three languages to some of the wealthiest families in NYC, San Francisco and Paris to make up for shortcomings in private schools they were paying up to $60,000 a year to attend.

Since 2015, I’ve helped hundreds of parents start microschools (way before this was a household buzzword). I founded CottageClass, the first marketplace for microschools and learning pods that was part of the Techstars 2018 class. In 2019, I created a virtual learning program to help families through the pandemic, a free online math tutoring program (masteryhour.org), and schoolclosures.org, a hotline developed in collaboration with Twilio and 80 other partners including Khan Academy, Revolution Foods and the Crisis Text Line, that served 100,000 families impacted by school closures.

I’ve climbed trees with children in forest schools in San Francisco, and tested new digital apps with kids in seven countries.

I’ve also coached dozens of families at different stages in their homeschooling journey. Most recently, I founded Modulo with homeschooling dad, best-selling author and tech entrepreneur Eric Ries, to help families curate their children’s education, social and childcare experiences drawing from a diverse array of in-person and online resources.


During the last three years, I’ve devoted much of my time to reviewing and testing secular homeschooling curriculum and other resource. I’ve spent the last three years talking to thousands of secular homeschooling families, and poring over tens of thousands of secular curriculum reviews and testing physical curriculum and digital apps for with hundreds of students to find the highest quality, most engaging, personalized learning materials for every type of learner.

I’ve spoken about homeschooling and modular learning at multiple venues including SXSW EDU, NY Tech Meetup, and on the LiberatedEd podcast.

In 2022, Modulo was one of 8 organizations who were awarded the Bridge Grant from the Vela Education Fund to expand access to homeschooling and modular learning to under-resourced communities.

My experience in education and homeschooling has led me to believe that there is no perfect education for every child, but families have an extraordinary amount of wisdom they can apply to building the perfect education for their individual child.

My goal with Modulo is to make it possible for any family to easily build a customized education that their child will love, and that will empower the whole family to thrive, taking into account, social, emotional and academic needs.

I love to answer questions from parents and receive feedback on how we can improve Modulo, so feel free to reach out anytime! I personally answer all the questions and comments readers leave on my blogs.

In my free time, I like hiking, traveling the world, tasting ceremonial grade matcha, enjoying dark chocolate.

I graduated Summa Cum Laude from Brandeis University with highest honors, with a double degree in French Literature and American Studies and minors in Environmental Studies and Peace & Conflict Studies.

And I love to learn!
