mix up.

'Mix Up' provides students with two contexts for visualising average percentages.

Your students can choose to use either bags of objects or jars of liquid. They can then choose the number of bags or jars they want to work with.

They are given clues to help them and if they still have difficulty the mixer will mix the bags or jars up and show what happens if they are shared equally.

The Before and After button shows a graph of how the objects or liquid was shared before and after the mixer shared them equally.

"Mix Up: equal sized" provides problems where the containers used are all the same size.
"Mix Up: different sized" provides problems with different sized containers, so that weighted averages need to be calculated.
