This is a 29 Slide PowerPoint lesson on multiplying whole numbers. This covers some word problems, mental math of numbers that are multiples of 10, estimation, and even has some exponents on the last few slides. There are even slides on the multiplication of larger digit numbers by larger digit numbers. All slides are animated with sound. Click, the problem pops up and students work it out, click again the answer pops up, click again a new problem pops up, etc. I like the sound feature as my students start salivating sometimes are they are well conditioned!!!
