Decimal Multiplication

This 19-slide PowerPoint presentation develops the procedures used to multiply decimal numbers. This presentation is based on the 6th grade Common Core math standard: CCSS.Math.Content.6.NS.B.3. It can be used for class or individual instruction. Use it on your teacher web page as a student resource when needed. The presentation should take about 20-30 minutes of class time depending on stopping points you find necessary and student participation. The presentation begins demonstrating how you line up numbers by place value in decimal addition & subtraction and asks if we should do the same for multiplication. Then the product is found by 1st converting the decimal numbers into fractions and then back to decimals at the end. Analyzing the steps in that method leads to the determination of a simpler procedure to use in decimal multiplication. The new procedure is used to find a product with numbers lined up & not lined up by place value. A practice word problem is given at the end with the solution worked out as well.
