On 20 and 22 April 2021, we hosted NRICH Live events for Primary and Secondary teachers respectively. During the events, we worked on some problems from the latest features, and considered the valuable mathematical thinking that the problems might prompt in classrooms.
Recordings of both events are below.
The event for teachers of 5-11 year olds focused on Exploring Factors and Multiples. Although the 'feature' referred to is no longer available, all the resources within it are still accessible:
Using Books: The Doorbell Rang (Early Years activity)
Dicey Array
Largest Even
Tables Teaser
Light the Lights
Light the Lights Again
Dozens
Playing with Factors and Multiples (article)
