Now I can take those things and divide by two. Into things that are easier to divide by two, and "plus 60, plus eight." I just broke up the 268 All I did is I took the 268, and I said, "Well look, this is the same thing as "200 plus 60. Now why is that useful? Well, now each of these, it's So this blue area is 200 units, this yellow area is 60 units, and this magenta area is eight units. Here is still two units, two units, but I've broken it up. So it's the same field, this dimension right over So here I have the same field,īut I've just broken it up. And so one way to do it is, is to break up this 268 square unit area into areas that are easier Me drawing this rectangle, or this aerial view of this field, or whatever you want to call it, is so that we visualize it using area. What 268 divided by two is, but the whole reason of Or we've already seen, multiple ways to figure out Out the length of that side, it would be 268 divided by two. Two sides, you get the area, so if you start with the area, if you start with 268, 268, and you divide by the other side, divide by the other side, you're going to get the length What is this side, what is this side of this rectangular, of this rectangle, thisįield, whatever this might be, what is the length of that side? Well if you multiply these So if you know the wholeĪrea is 268 square units, and one side is two units, what's the other side going to be? What is the other side going to be? What is, what is. Scale, it would be like, it would be much shorter, And I haven't really drawn this to scale. let me just hit a color, let's say you knew that this side of theįield right over here, the length of this side And lets say you knew the dimensions of one side of the field. You could imagine themīeing square centimeters, or if you imagine this being a big field that you're looking at from space, it could be square miles or something. I'd love your ideas on this.That this rectangle, this green rectangle right over here, let's say it had an area of 268 square units, whatever those units are. Hearing this it makes a lot of sense, especially if the videos will be used for distance learning or as the main math lesson. My whole goal with the videos I've been making is to get right to the point, but I did get some feedback to add some wait time to this video so that students can work along with it. I guess I can take it as a reminder that we can do anything we put our minds to. How can any one person teach another person how to read? It always seemed like magic. You know how they say, "Never say never"? Well I can't count the times I have said that I could never teach kindergarten. As hectic as this time at home has been, a silver lining has been seeing math through the eyes of a little person. My daughter has been wanting to be in my math videos so will be part of a couple coming up. I have a lot of videos planned to add- prime numbers, even and odd, more to go along with my free math cheat sheets. I've been building a visual math playlist on my YouTube channel with videos for fraction multiplication and division, solving equations, ways to use algebra tiles, strategies for tackling integers, etc. In this post I want to share a multiplying fractions with visual models video. A few weeks ago I blogged about a few digital fraction multiplication resources for Google.
