Word Problems Subtraction First Grade 1 st Grade Math Video

hello kids welcome to the DodgeBall gym today we will be learning about subtraction in word problems we have some fun stuff to learn so let's get started does anybody know what this sign means when we see it in math problem this sign means to subtract and some other words for subtract are to take away or minus today we are working with word problems which are just stories about math here is our first word problem it says have seven balloons and then two of them pop how many balloons do have now remember it is good to read it second time have seven balloons and then two of them pop how many balloons do have now believe that this math problem is asking us to take away because it said that they had seven balloons but some of them popped if balloon pops you no longer can play with that balloon so they go away so we will be taking two of them away just like it says in the word problem I'm going to start this with circle drawing circle drawings are great way to illustrate math stories or word problems am going to use seven circles to represent the seven balloons that we started with here are the seven balloons the problem says that two of them popped do you think this means that it will take away two balloons or add two balloons we will take away two two balloons because they popped will put an on two of these balloons to show that those two went away now the rest of the circles that do not have an are the balloons that have left this is an awesome way to figure out the math problem we need to write an equation to go along with this word problem if you remember we had seven balloons total at the beginning so we will write the total or seven first because this is how many we had before any of them popped then it told us that two of those balloons popped we will now use the minus sign or the takeaway sign which tells me that I'm going to take away two of those balloons that popped when we take the two balloons away how many do we have left looking at the circles we started with seven and two popped and that leaves us with 1 2 3 4 5 we have five balloons left great job kids you guys are awesome let's quickly do math Mountain even though we have figured out the word problem the really cool part about subtraction problems with math mountains is that usually we know the total in this problem the total we started with is seven the seven is at the top because it is the total we started with also know that of those seven balloons two of them popped the two goes down as one of the partners how many are left after the two balloons popped the empty box is where the answer will go and it will be how many balloons are left after two balloons popped we know it's five because we counted in our Circle drawing and there are five balloons left we can check our work with the math Mountain because we know that 2 plus the other partner 5 equal 7 which is the total awesome kids let's do another problem and see if you can do it this time we are going to start by writing math Mountain an equation and then circle drawing to prove the answer here is another word problem it says eight children are playing then five have to go home how many are still playing let's read this one more time eight children are playing then five have to go home how many are still playing let's start with math Mountain will give you moment to do it yourself okay can tell just by reading this problem that have total because eight children were playing and some had to go home so our total is eight which which goes at the top of the math Mountain we also know that five of the children had to go home five is one of the partners we need to find out how many of those eight children are still playing after five went home as we can see we have total and we have one of our partners we need to find out the other partner with this information we can now write an equation what is the equation we have eight kids that we playing so we will write our total total first because all good subtraction problems start with the total then will put down the subtraction sign five of them had to go home so we put down five and now there are still some playing but we do not know how many that is what is 8 takeway 5 the answer is three 8 subtract 5 is 3 amazing job kids to check our work we can use circle drawing here we have eight circles to show the total amount of kids we started with now we subtract five circles because five of the kids went home this leaves us with three circles which proves our answer you guys did an awesome job thank you for helping me we will see you next time goodbye thank you for watching please share the video and subscribe
