Content block: Matching with three sets
In this content block, the solver can form pairs between the 2nd and 1st sets and between the 2nd and 3rd sets. The number of pairs that can be formed between the sets is determined by the task creator. Currently, each element of the 1st set can be paired with only one element of the 2nd set, but each element of the 3rd set can be paired with up to two elements of the 2nd set. In the evaluation matrix, the relationships between the 1st and 2nd sets and between the 2nd and 3rd sets are assessed independently of each other.
To connect the elements, they must be dragged on top of each other (the lower element must turn gray). To remove the connection, the drag motion can be repeated or then click on the line connecting the elements with the mouse.
Align the formula, name, and class of matter for the chemical compound.
Connect the elements in the set by dragging matching elements on top of each other. Do not release the mouse until the bottom box turns gray.
Content block: Matching with three sets and triple evaluation
As in the content block above, "matching with three sets", here the solver must form relationships between the 1st and 2nd sets and the 2nd and 3rd sets. The difference here is in the evaluation - the relationships are evaluated together, i.e. the solver has to form the right trio to get the point.
