Ch-ch-ch-changes! Mathalicious is now Citizen Math . Please visit www.CitizenMath.com for the real-world math lessons you know and love. Alternatively, you can continue to access Mathalicious.com until the end of the school year, at which point Mathalicious will ride off into the sunset.

Finding the Right Mathalicious Lesson

The first step in teaching a great lesson is finding a great lesson. We provide teachers with a variety of ways to find the right Mathalicious lessons for them and their students. Teachers can search by mathematical keyword (e.g. "exponential") or real-world topic (e.g. "exercise"). Every Mathalicious lesson is aligned to the Common Core Standards, and teachers can search by those, too.

Teaching is hard enough. Finding the right lessons should be easy.

Planning, Teaching, and Reflecting on a Lesson

As teachers ourselves, we understand how much preparation goes into teaching an effective lesson. We provide teachers with the resources and support they'll need to use Mathalicious lessons successfully. Mathalicious lessons are intended to last around two days (on a block schedule). They revolve around a guiding question, and provide the right mix of student scaffolding and open-ended exploration. In addition to this core activity, select lessons also include optional project-extensions. These 3-day activities allow students to explore a topic in more depth, and are great for teachers, schools, and districts interested in incorporating more project-based learning (PBL) into their instruction.

Every Mathalicious lesson happens in three stages, and the lesson page is divided into three parts:

Plan Tab

The Plan tab provides a lesson overview, student objectives, a list of the Common Core Content Standards, and the Common Core Mathematical Practices. It also offers suggestions for when to use the lesson, including prerequisite student skills.

Teachers can download a student handout and a detailed lesson guide. The lesson guide offers suggested student responses, common misconceptions, guiding questions to help check for understanding, and deeper understanding questions that challenge students to think even more critically.

Teach Tab

Once a teacher has prepared a lesson, she can head over to the Teach tab. The Teach tab includes all the questions from the student handout, as well as images, videos, and other interactive tools that help bring the lesson to life.

Every Mathalicious lesson begins with a Preview: an open-ended "hook" that gets students discussing the topic as a class. A teacher uses the question buttons at the top of the screen to progress through the lesson. The layout is clean and intuitive, and allows teachers to focus less on using technology, and more on teaching math!

Reflect Tab

The best teachers are always trying to get even better. Once a teacher has finished teaching a Mathalicious lesson, she can share her experiences, and to get feedback from other teachers around the world.

Professional development is often abstract and irrelevant. However, the Reflect tab allows teachers to collaborate around a specific lesson. While there's no substitute for working together in person, this offers a unique opportunity for teachers to engage in meaningful professional development...and then apply it in their classrooms.

Using Interactive Tools

At Mathalicious, we believe that learning is a social process. Everything we create is intended to help teachers engage their students: to ask interesting questions, and to create a classroom culture of curiosity, inquiry, and discourse.

While conversations are the centerpiece of every Mathalicious lesson, technology can play an important role in supporting effective instruction. Mathalicious lessons include a variety of tools, from dynamic graphs to interactive tables, to animations that help students visualize the relationship between a television’s aspect ratio and its screen area. These tools complement the thoughtful questions that characterize Mathalicious lessons, and help students develop an even deeper conceptual understanding of mathematics.
