So many students struggle with b verse d letter reversals. This original version includes six self correcting Smartboard Slides. This b verse d Smartboard activity is perfect for a station or class activity. By pressing on the bed, B object or D object, "b" or "d" or the name of the object is spoken. The student must write on the Smartboard "b" or "d". There is also a self correcting opportunity, as the correct answers are hidden under animated objects. The original version only contains 6 slides. The advanced version is just a little more expensive but contains over three times the original content.
