To celebrate NRICH's 20th birthday we have selected some 'hidden gems' to share with you.
We have chosen some tasks which you may not have come across before, perhaps because they are not so closely linked to the curriculum, perhaps because they have not been featured recently on the website or perhaps because they are relatively new. However, all of them are rich mathematical activities which will intrigue your learners and encourage them to think mathematically. To find out more about the reasons for selecting each one, take a look at the article below.
We hope you enjoy exploring.
