Attribute Blocks
Web Link: Attribute Blocks Virtual Manipulative/Venn Diagrams
Flexibility: This applet allows students to sort attribute blocks into one, two, or three circle Venn-Diagrams. It may also be used as a blank canvas to create patterns or organize shapes and colours. You can only spawn one colour and one shape of each, which may be a limitation for other uses. A walkthrough for its intended use is available here.
User Interfaces: Works well with mouse and touchpad, works well with table and cell-phone touch screen. However, the app does not resize itself for each screen.
Browsers: Works will all major browsers.

Web Link: Interactivate: Venn Diagram Shape Sorter (shodor.org)
Flexibility: This applet allows students to sort attribute blocks into one, two, two-overlapping circles. Students first set the type of Venn diagram they want and then they set the rules of each circle. They then attempt to drag over the proper colour and/or shape for the right circle. The game keeps a score of how many they have gotten right and rejects any that are dragged to the wrong circle. There is also a mode for students to guess what the rule is by guess and check.
User Interfaces: Mouse and touchpad friendly. Works with touch, but needs slow and deliberate gestures.
Browsers: Works will all major browsers.
