The Activity Builder allows the user to put objects on the page and choose one object to be the activity object. Let's say the activity object is the number 4. The other objects on the page either go with the number 4 or they don't.
Once I have the objects on the page, I click on the puzzle icon on the side of my screen. This is the Activity Builder.
To choose the 4 as the activity object, I select the number 4 and reselect the puzzle icon.
Then I click and drag each of the other objects to the "accept" or "reject" boxes in the Activity Builder menu.
For efficiency, I dragged the three objects to be rejected to the reject box and then clicked "Add All Remaining" in the accept box. Nice to have.
Once all objects that are part of the activity have been added to the appropriate boxes, you can choose to adjust settings or click "Done". In the "Settings" tab on the Activity Builder menu you can choose the animation of the objects, such as fading out or bouncing away.
Now students can come to the board and drag the objects that make the number 4. If they are right, my objects will fade into the 4. If they are wrong, the object bounces back out.
Promethean has a way to make an activity just like this (See "Creating Containers"), but for once, SMART made it a lot easier and faster. Use this activity whole group, small group, or for centers. It allows interaction and instant feedback. Awesome!
