This Place Value Smart Board lesson covers a review of place value of whole numbers to a hundred million. It includes word form, standard form and expanded form. It is interactive with lesson pages that are linked back to the target goal page for easy reference. I've included what I call 'Firecracker Math" with a pull down screen where students do math quickly in their heads. There are also erase and reveal pages for student practice, This is a great first day lesson for 4th or 5th grade review. Any additional page can be added to the SB lesson by dragging the page in pdf form to a new slide.
