Additionally, I don't know if the kids watch Animaniacs any more, but I think if they do, the familiarity with the characters will spark their interest and get them to pay attention. Unfortunately I find that this is an everlasting battle with children of this generation.

It does mention the rules for multiplying by 0 and 1, but it really focuses on the 2 and 3 times tables.

I like the Khan Academy videos because they provide a visual along with the audio lesson. This helps students who are more visual learners, as well as the fact that it gives students something to visually focus on and therefore keeps their attention. I love the fact that they thoroughly explain the rule of moving the decimal point in the product the total number of places it has been moved in the two factors combined. I am skeptical about their choice of using 0.5 as the second factor. I question it because of the 0 in the ones place. Since my students have been focusing on (and struggling with) two digit multiplication, This would prompt the question from my students, and I wish the video would at least acknowledge that they have disregarded the 0 because 0 times anything is 0 and when you add 0 to any number, the sum is that same number. I also don't like the selection of 0.5 because of what they say at the end of the video about checking. I see why they chose 0.5 so they could check this, but this would just confuse my students. They have yet to discover that multiplying by 0.5 is the same as dividing by two, or that the answer should be close to half. For this reason, I will stop the video after they get the answer.
