Global Maths Twitter Task Challenge

The Global Maths Twitter Task Challenge is a 

great idea from 

Beverley Ladd and Heidi Samuelson.

Classes from around the world can join in. The project will continue for the rest of 2015, and into 2016.  

Questions are tweeted out using the #gmttc hashtag 

(with the grade level added to the end). 

Some classes have signed up to host the questions for their class level for a week, while other classes are just choosing to join in by answering the questions.

We were one of two classes hosting the questions for the week 21-25 September, using the tag #gmttc1

In B4 we like open-ended questions, where there might be more than one solution, 
and we started the week with this tweet:

There was a lot of excitement when some classes answered our first question!

It has been a lot of fun and we've enjoyed seeing how everyone works out the problems.

Do you have a problem we could solve?
