Do you have any tutorials or lesson plans for teachers?

Take a look at our Teachers page for a summary of all the tools and resources we offer to teachers, as well as different tutorial videos.

We also have a large library with more than 70 tasks and lesson plans for Polypad, covering the entire mathematics curriculum.

Polypad

I have ideas for a new tool or feature to add to Polypad.

Every week, we are adding new tools and features to Polypad. If you have any ideas for something new, please let us know!

Can multiple users work on the same Polypad canvas at the same time?

This is not currently possible, but we want to add more collaboration features in the future – including having multiple users edit the same Polypad canvas simultaneously.

How do I share a Polypad canvas with students?

There are many ways to share canvasses with students: you can share the link directly, assign the canvas to a Mathigon class, or post the canvas link to Google Classroom. Watch this video to learn more!

How do I add question fields to Polypad and see students’ answers?

If you have a teacher account, you can add self-marking question fields to a Polypad, assign it to your class, and then review students’ responses or download a summary spreadsheet. Watch this video to learn more!

How can I contribute to the Polypad tasks page?

Our Polypad tasks page contains many different lesson plans, activities, tutorials and teaching ideas for the entire mathematics curriculum – and we are looking for teachers to contribute additional ones. This page explains how you can submit your ideas, and thanks so much for offering to contribute!

How do I embed Polypad on other websites?

If you have saved a Polypad canvas, you can embed it on other websites using iFrames – and even customise which tiles and toolbar options you want to show. Watch this video to learn more!

Can I use Polypad commercially?

You can only use Polypad for non-commercial purposes: this includes in schools or universities, for educational research, or embedding on personal blogs and websites. You can publish screenshots taken from Polypad as long as you include a credit line to Mathigon.org underneath the image.

If you want to use Polypad for something ele, please contact us to sign a commercial licensing agreement.

Interactive Courses

Some of the courses are listed as “under construction”. When will they be released?

Building our interactive courses takes a long time: from research to writing, graphics design, and programming. Unfortunately, we cannot promise when a specific topic will be finished. However, our team of writers and engineers is always working on new content. If you have a Mathigon account, you can subscribe to our email newsletter to receive regular updates.

Can I see all the content in a chapter at once without having to answer each question?

Mathigon’s courses are divided into many small steps, and we want students to actively participate at every step before we show the next one.

However, when you first visit a page, there is a grey banner in the top-left corner which shows the approximate length of this chapter, and allows you to reveal all content at once. Later, you can also scroll to the very bottom of the page and click either “skip to the next step” or “reveal all steps”.

Please note that revealing all content will disable some of Mathigon’s personalisation features.

Should I complete the courses in any particular order?

Not necessarily: the chapters within a course do build upon the ideas from the previous chapters, but students can always go back as needed.

I think I found a mistake in a course. How can I let you know?

Thank you helping us to improve Mathigon. Simply send us a message using our contact form!

Can I disable Archie, the virtual tutor?

Our virtual tutor provides hints and help if students are stuck, or encouragement if they answer questions correctly. Students can also ask questions, which we try to answer directly, using Wolfram|Alpha, or by finding appropriate educational YouTube videos. It is not possible to disable the tutor.

Can I track my students’ progress in courses?

Yes! You have to create a teacher account and link your students to one of your classes. Then you can track their progress on your teacher dashboard.

Activities

How do the Multiplication By Heart flashcards work?

Our Multiplication By Heart flashcards use an approach called spaced repetition, to show students the cards they are most likely to forget. Every day, we pick up to 40 different cards based on students’ previous work, each containing different visual representations.

All cards start in Box A. Cards answered correctly will move to the next box, and cards answered incorrectly move back to box A. There are three decks of cards which will be unlocked consecutively. In shuffle mode, students will instead see a random selection of cards from all decks. You can track your students’ progress on your teacher dashboard.

Watch this video to learn more.

What if students see no (or very few) flashcards on their Multiplication By Heart page?

Multiplication By Heart is designed for a few minutes of practice every day. Once students have answered all questions on a given day, they will have to wait until the next day to get new cards.

Because of how spaced repetition works, there might be days were students are shown very few flashcards – or even none at all. And once all cards reach the “memory” box at the end, students will never get new cards again. This is completely intentional: by then, students should be fluent and won’t need to practice multiplication facts again.

However, we also have a “shuffle mode” version of Multiplication By Heart, where we simply pick a random subset of cards, without spaced-repetition of saving students’ progress.

How do I track my students’ progress in Multiplication By Heart?

To track your students’ progress, you need to create a Mathigon teacher account, setup a new class, and link your students to that class. Finally, click the green Multiplication By Heart link in the sidebar of your teacher dashboard to review your students’ work.

How did you decide which mathematicians to include on the timeline?

No timeline can ever show everyone who has contributed to mathematics: because of limited space, but also because research and discoveries were often misattributed throughout history. On our timeline, we tried to select both those mathematicians and artifacts who had the greatest impact, and those who best show the diversity of mathematicians. We are regularly reviewing our content and adding additional mathematicians and artifacts.

Teacher Accounts

How do I create a class and add or delete students?

This video shows how you can add and remove classes and students on your teacher account.

I created a student account – can I change it to a teacher account?

Yes – simply go to your account settings page and then click the corresponding button.

Can I add a co-teacher to my Mathigon classes?

We don’t yet have a user interface for adding multiple teachers to the same class. However, you can send us a message including your class code as well as the email address of any additional teachers you’d like us to add to that class. Make sure that these emails are the same as the ones the new teachers used to create their Mathigon accounts.

Can you sign a Student Data Privacy Agreement with my school or district?

You can visit the SDPC website to see if another district in your state has already signed a data privacy agreement with Mathigon. In that case, you only need to complete Exhibit E and email us a copy.

We can only sign privacy agreements that closely follow the SDPC template. Since Mathigon is a free product, we cannot reimburse schools or districts for any costs related to using Mathigon – including data breaches. Please get in touch if you have questions.

This answer only applies to schools in the United States
