Zij biedt een platform voor personeel (leraren, directeuren, bibliothecarissen, enzovoort) dat werkzaam is op een school in een van de Europese landen en via het platform communiceert, samenwerkt, projecten ontwikkelt en deelt. Kortom, zich onderdeel voelt en onderdeel is van de boeiendste leergemeenschap in Europa.

Collaborative Mathematics offers a set of 16 mathematical problem solving challenges, each presented in a short video. Problem solvers are invited to watch the videos, give the problems a try, and create a response video in which they explain their solution.

The individual challenge pages are linked below. Each page includes a student handout, and many include links to response videos submitted by participants. Teachers may also wish to visit our curriculum page, where we offer a lesson outline with tips for structuring a class period around exploring and discussing a Collaborative Mathematics video challenge.

Read the profile of Collaborative Mathematics on Math Munch.

Julie T. from Superior, Wisconsin says: "I teach a higher level 5th grade math group and the challenges have been some of the best discussion this year! The challenges have forced them to think about their thinking and explain it to others."

Listen to a discussion from the very first days of Collaborative Mathematics on the podcast Inspired by Math.

The cosmic microwave background (CMB) is light left over from the Big Bang. It has revealed a wealth of information about our Universe and turned cosmology into a precision science. How can a single picture tell us so much?

I'm going to let my bright dutch student try to follow and replicate this one:

Text Book problem in real world. Found this one on the shared padlet. Goint to use it next week as we deal with Phytagoras right now. Homework will be to do the same with TV at home.

PBL - The problem with following the book is that projects always overlap one chapter. And adressing all the topics of one chapter in the book in a project seems unrealistic. Another example why I need to get rid of being a 'slave to the book'. Nice ideas can be find here:

Personalising my classroom

I try to personalise my classes by allowing student to make more or less work. I challenge them by beginning at the end to find out how great the gap is between where they need to go and where they are. The problems is then the instruction moments, because student are at different levels/points in their learning. I want to discover more ways dealing with that. With in mind: they have no personal device with them all times. So solving my problem with just technology is an obstacle at this moment.

At the start of the MOOC I created this diary.

I hope to learn ways to make my math class more interresting and challaging form my students.

I am a dutch Math teacher, teaching in the city of Leiden to 12 - 16yrs old students on different levels. This year I started to go gradeless with one class. My collegues teaching English and geography also don't give grades. With two other we started the facebookgroup "Actief leren zonder cijfers" which is the dutch vesion of the group "Teachers throwing out grades".  Formative teaching / formative assessment is starting to get a lot of followers over the last year, which is a good thing in my humble opinion. I hope to learn a lot of eacher other!
