This interactive environment can be used with children, perhaps on an interactive whiteboard, for many different purposes. These might include, for example, exploring ideas associated with factors and multiples or addition and subtraction. It is also an ideal context in which to investigate fractions and ratio, or to look at finding combinations. You can also explore number patterns. By asking
different questions, the environment can be put to all sorts of uses.
You can also encourage children to 'play with' the interactivity themselves, perhaps in pairs.
For NRICH problems which specifically mention the use of Cuisenaire rods, go to the Maths finder
and select 'Mathematics Tools'.
