I have these three star patches I guess you could call them right over here and so I could say if I had one group of three star patches how many star patches do I have so I literally have one group of three star patches well that means that I have three star patches one two three this is my one group of three now let's make a little bit more interesting let's say that I had two groups let's say that I had two groups of three so that's one group and then here's the second group here's two groups of three so how many total star patches do I have now well I have two groups of three two groups of three or another way of thinking about is this is three plus three this is equal to three plus three which is equal to six equal to six so we see one times three one group of three is three two groups of three which is literally two threes is six let's make it even more interesting let's have three groups of three three groups of three now what is this going to be equal to what's three groups of three so I could write this as three groups three times three and how many of these star patches do I now have well this is going to be 3 plus 3 plus 3 it's going to be 3 plus 3 plus 3 notice I have three threes I have two threes I have one three so this is 3 plus 3 plus 3 is equal to is equal to 9 and you can count them one two three four five six seven eight nine or you could just count by threes three six nine and I think you see where this is going let's keep incrementing it let's get four groups of three so let's think about what four times three is one two three and four this right over here is four groups of three we could write this down as four times three four times three which is the same thing which is the same thing as 3 plus 3 plus 3 plus 3 3 plus 3 plus 3 plus 3 notice I have four threes one three two threes three threes four threes 1 3 2 threes three threes four threes so we get 3 6 9 12 12 so what I encourage you to do now now that the video is almost over is to keep going I want you to figure out what 5 times 3 is 5 times 3 and 6 times 3 and 7 times 3 and 8 times 3 and 9 9 times 3 and 10 times 3 and I'll give you a little hint you don't always have to draw the star patches but it's nice to visualize it we saw 4 times 3 is only four threes well 5 times 3 is going to be 5 threes so 2 3 4 5 5 which is equal to 3 6 9 12 15 15 so I encourage you to think about what all of these are after this video is done
