Decimal Discounts using the Smart Board is one I developed to get materials for a sixth grader not understanding the concept. You will have five items a student might buy that involve using an original price and a decimal discount. Students are asked to find the amount of savings as well as new price. This activity could be used for small group instruction or in a math center. Additionally, it could be used for entire class instruction.
An answer key is given on the last page (pg 7) for you or for student self checking.
