We have just uploaded a number of new FX Library MultiDocs including a nice little right angle trigonometry investigation.
Measuring Heights & Depths Investigation
This investigation looks at calculating the heights and depths of inaccessible objects.
The validation section of the investigation has been parametized to allow multiple versions to be produced.
FX Library MultiDocs provide you with prewritten materials that you can use as-is or you can use the MultiDocs features to generate new versions at will. They also provide exemplars on how to create your own MultiDocs. We recommend that you keep an eye on FX Library by pushing the Library button on our new Word toolbar.
