I go ahead and stop by writing your name on the top of your paper before I start this can you make sure that you have two different colors either two different colored pens or color pencils excetera  so an assassin is going to be 12 3A area models the objective is that students will be able to find the area of a rectangle with fractional side lengths using an area model example number one is Jenny's Garden is a rectangle that is 3/4 yards long and 2/3 yard wide what is it I've heard Garden  we're going to create an area model to be able to solve this I'm going to be looking at my denominators I'm going to go how to make this pink and circle the other two go ahead and make sure that you're falling along so I could one color I circled it pink and another can you want the different colors synthesis 3/4 I created for my daughter is 1/4 I needed four columns  and since this is 2/3 my denominator is a three I needed three rows and that's how I created this this is already given to you guys but if it wasn't you would need to have a graph paper or your ruler and create your own area model cell again since my daughter is a four I created four columns and insist armor is a three I created three rows no I'm going to look at my numerator my numerator is a three that means I'm that color three of the color cake  I watch me too. Cuz I want to be able to see the green I'm just doing lines that's one chill free again because my numerator is a three I colored only three columns can I go ahead and look up this time remember this I have three rows look at the Rose and I need to color only two of the Rose because my numerator is a shoe okay it's okay me too I'm going to go ahead and do the top two hey so here's my first here's my second why did my two rows green no credit by friction and what my answer would be if I'm going to look at which ones are green and pink I have one two three four five six squares that are green and pink I'm going to go ahead and write 6  and actually going to go ahead and go over this with a different color 6 Mi denominator sixes green and pink whatever colors you used in your example my denominator is the total I'm not squares so I count and I have one two three four five six seven eight nine 10 11 12 at 12 total square to my drummer is the 12th the sex addict not when I'm looking at this example I have six at 12 and let's pretend this was like I failed 12 / 3015 and I had no idea whether or not they had a common factor I would need to be able to simplify action and know if it's in its simplest form or not I need to create a factor tree that we could know if a fraction is in its simplest form you need to create a factor tree so aren't you use my numerator and denominator so here's a 6 and here's the 12  I may have to go ahead and Factor those out pictures of 6 is on time I had anal sex is an even number so I know that two goes into it and when I think 2 times what equals 6 if I know where else cash let me know I'm actually is 3 otherwise if you don't you can always count by twos I have 246 so I know that it's two times three is six since both of these what are prime and remember Prime means that only one itself can go into it I'm going to go ahead and circle them cuz nothing else can go into it except for one and itself and I have my 12 and 12 is also an even number so I know that you can go into it if I know my a multiplication facts tell that it's 2 x 6 otherwise again he can count by twos and two four six eight 10 12 which is B6 just go into it sex is a composite number K that means that something can go into other than one and itself so when I'm separating out that six pics of even number as well sign of 2 can go into 6  and if I'm looking at what can go into 6 I know that 2 * 3 is 6 not for that I won't have a different color play like the matching game I can only match on different trees so I cannot match this tune to cuz it's on the same train so I can match on different trees I look that's too I can match with this to this three I can match with this 3 I have a 2 left over but there's nothing I can match it with for something I can do now go to do with my cover up one tree it doesn't matter which tree cover up the street to look at the numbers that are crossed out so I have A2 and A3 crossed out to write that too and I am not going to multiply those together for two times three is six this  sex right here is my greatest 10 Factor this is what I need to divide by to get a fraction in simplest form so I take my 612 men / 6 / 6 6/6 is 1 + 12 / next days to sunlight would be one hope so the area of this rectangle would be 1/2 and because when I go back to my original problem I'm talking about how long it is and yards I can write one half yard 1/2 yard okay and this concludes the lesson for 12 - 3
