Missing Numbers (Addition)


Interactive, Publisher, TeacherLED

This interactive whiteboard resource is useful for introducing children to the concept of having the answer but not one of the numbers in the question.  An addition is shown with an answer but not one of the numbers being added.  The “20″ button generates questions with an answer below 20.  The “100″ button generates numbers with an answer below 100.
