This 19-slide PowerPoint Presentation teaches the process of dividing by a decimal number through long division. It is based on Common Core 6th grade math standard: CCSS.Math.Content.6.NS.B3. You could employ this instructional presentation anywhere from 20 to 40 minutes depending on how much student interaction and stopping points are incorporated. This would also make for a great item to place on your teacher web site. Use it for full class instruction or individual use.
First it introduces a comparison between division with whole numbers & division with decimal numbers. Then it shows how models can be used to help solve some division problems while long division works better with others. Through the use of equivalent fractions and multiplication by powers of 10, the reasoning behind decimal point movement is explained in long division with decimal divisors. Word problems are used as examples and with practice problems. For similar helpful products, visit my store: https://www.teacherspayteachers.com/store/David-Purnell
