## NRICH at Every Stage

Whether you are pausing to reflect on children's learning so far, or thinking about planning an exciting mathematics activity to explore during some transition time, the article and tasks offer a plethora of ideas which could be slotted into different time frames.

So, if you only have a short amount of time, have a look at the problems we have selected. For longer periods of time, perhaps over a day or several days, the investigations are a perfect choice. However, you may choose to use a game, particularly if you are not sure if your audience will be super excited or a bit nervous!
