Counting American coins

CCSS.Math: ,

Video transcript

let's get some practice counting money so I have six coins right over here and these are all United States coins or counting money in the United States for these examples and what is this first coin well this is called a quarter or a quarter dollar so it represents twenty five cents and we could write it out as twenty five cents but I'll just write it as twenty well I'll just keep that one like that now this one is another quarter so it is also going to be it is also going to be twenty five cents now this one looks different but it's just the other side of this coin of these coins this what the other side looks like so this is this is also going to be twenty five cents these are three quarters right over here so how much how much money do these three quarters represent well it's going to be 25 plus 25 which is 50 plus 25 which is going to be 75 so these three quarters are going to be 75 75 cents and remember a hundred cents make a dollar so this is still less than one dollar but we're not done yet we have this nickel this is a nickel right over here that represents five cents and then we have another nickel here it looks different was just the other side this is the head side this is the tail side so this is also another five cents and so these two nickels if you add them together they are going to represent ten ten cents and then finally you have a penny and a penny and it even says it right over here is one cent in fact they all say it here this is five cents this says one cent so this right over here is going to be one cent so what is 75 plus ten plus one well 75 plus ten is 85 plus one is 86 so this is equal to 86 cents and if it was if it felt a little bit too fast to count up 25 50 75 in your head you could also add them up 25 25 25 plus five plus five and another five plus one plus one you could add them up this way and then what would you get 5 plus 5 is 10 plus 5 is 15 plus 5 is 20 plus 5 is 25 plus 1 is 26 so that's two tens and one six put the two tens up here 2 plus 2 is 4 4 plus 2 is 6 6 plus 2 is 8 so you could get 86 cents either way let's do one when it has even more coins in it so here we go we have so what is it what's going on here this right over here is 1/4 that's going to be 25 cents 25 cents and then we have one that we didn't see in the previous example we have two dimes a dime represents 10 cents so we have two dimes or we could have those each represent 10 cents then we have two nickels we've already seen those each represent five cents so five and five and then we have four pennies 1 1 2 3 4 now we could put each penny separately like that or we could say look for pennies each of them represent 1 cent so that's going to be 4 cents so let me do it that way so so this 1 2 3 4 that's going to be 4 cents and then we could just add everything up so 5 plus 0 plus 0 plus 5 is 10 plus 5 is 15 plus 4 is 19 19 is 110 and 9 1 so I can put the 110 in the tens place 1 plus 2 is 3 plus 1 is 4 plus 1 is 5 so it's 5 tens five tens and nine ones so 59 cents this right over here is 59 cents and notice we have more coins but it represents less value than the previous example that's because we had a lot of coins that didn't represent a lot of values like we had these four pennies here well in the previous example we had three quarters quarters represent each of these quarters is equivalent to twenty five pennies so we're able to represent more money with fewer coins in the first example
