Using objects in your classroom, make a model of a set (that adds to 10 or less). Open Pic Collage and select freestyle. Take a picture using the camera on your iPad. Next, use the Doodle tool to cross out some of the objects. Finally change the background and type your name. Now, switch with a partner and ask him/her to type a number sentence that goes with your picture. You can make another model and follow the same steps if you have time.
