back to you but we will be doing for today so today we learned yesterday how to use over 100 chart numbers we also look at how we could use a number line to add the number today we are going to look at how we can use these tools to subtract numbers so remember boys and girls When You Subtract me go backwards so if I subtract wine from China with movable pop one back to 110 - 1 equals 9 9 - 1 equals 889 1 equals 7 7 - 1 equals 66 - 1 equals 5 minus 1 equals 4 4 - 1 equals 3 3 - 1 what's 2 + 2 - 1 equals what minus one equals zero so we can use a word 100 chart to add and subtract also use our number line to add and subtract so 20 - 4 and see what we get one two three 420 - 4 equals 60 let's see what's 16 - 412-232-6094 well today we're going to come backwards because when you come back words we are subtracted so let's have your listening eyes listening ears and listening Miss Cora I can hear it I cannot can hear it okay you can go ahead and meet your mom thank you my let's go from 100 99 98 90 790-695-9493 190-389-8887 86-84 970-877-7671 5968 57th 5955 54th 351 4746 4544 4241 39 38 37 36-35 3433 3231 29th Way 2736 25 24 23 22 June 17th team 98.7 100 Brave if you go backwards we are subtracting numbers and we always subtract smaller numbers from the bigger number okay so here we have our numbers always remember each number has a name so this is the number that's the spelling for 1 spelling for 23434 spelling for 4545 spelling for 6 7 spelling for 7889 spelling for 9 10 11 11 12 or 12 13 14 numbers 14 spelling for 14 15 spelling for 1516 the spelling for 16 17 17 18 18 19 spelling for 19 and we have to empty the first we have spelling for the rest of the number so let us look all we can subtract to one using the number line so I'm going to go ahead and the statues a number so I need a number and I will shoes let's go back up here I will shoot the number 11 I'm going to chew the number 11 and 11 is an odd numbers so let me go because it ends with someone I'm going to go ahead and write 11 now if I want to subtract a number boys and girls I have to subtract a smaller number than 11 so I am going to go ahead and say shaktimaan going to subtract 10 well I'm going to go ahead and subtract 10 from 11 so I am going to circle 911 and I am going to subtract 10 Cora All Eyez on Me if I am subtracting a smaller number is bigger than I have to hop backwards how many hops am I going to make I'm going to make 10 Hawks backward one Siri 6 789 so I know that the difference between 11 and 10 is 1 let's do another what so this time boys and girls I am going to go ahead and subtract 1 from 11 to 3 I on me so I am going to go ahead and subtract 1 from 11 so here I have my 11 and put in a circle so if I am going to subtract 1 I only need to hop what color are your eyes are on somebody that's not on me so if I'm going to subtract one I just need to have one so I know the difference between 11 and 1 is 10 back one I will land on so we will be doing just one more just to make sure that everybody's eyes were on me let's go I still one more and then we will do one together so let's look at since most of the children are six we're going to start with sit I am going to go ahead and put the circle around 6 to my I'm going to say 6 - 1 what's the difference what's the answer 6 - 1 I just seen one harp and I landed on my difference between 6 and 156 - 1 is equal to a difference of so now that we have done that together boys and girls let us see brilliant boy or girl can help me out just a little bit I am going to say 10 Aaliyah's $10 a lesson from other number 9 - what so turn and tell your classmates what you will do on the number line to get the answer so tell your classmates what you will do open your minds and talk to your classmates and tell them what you will do 9 - 1 is 8/8 9 - 28 okay see you talkin to your clan let's hear what you were saying how would I show this on the number line why do where would I start on my number line rounding 9 what would I do next 7191 what will I do next on my number line do want to jump forward backward backwards good so I'm going to go ahead and do my wall Hall and that confirms your answer is 1 is equal to how about if I had this is this big number 20 9 oz what beer would be by answer 20 - 1 raise your hand if you have the answer 20 - 1 what 9191 okay you almost got it but you turned it the other way it's 90 I'm the one comes before the 9th so very good 90 how would I do my practice on my number grid on my 100 chart where would I Stay if I wanted to subtract 1 from 20 let me see which brilliant boy and girl can help me to use my number grade London where would I start on my number if I wanted to subtract 1 from 20 which number will I Circle London England this number life cycle London okay go ahead Carter 2019 hot bath with words and their we have we stopped at 19 so that is why I 20 - 1 do you like difference of u93 good job boys and girls so we are going to look at another video this time we will be counting up and back can you do let's count from 1 to 20 are you ready 1 2 3 4 by 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 thanks for counting now let's count backwards from 20 are you ready 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 backwards and forwards with us don't forget to 2:20 and then back from 20 so boys and girls this is what I need I need you to do for me I need you to get 10 counters 10 counter Harrison you have your counters do you have your kitchen counters I have 11 11 okay so everybody should have had their 10 counters by not so what we will be doing together and then you're going to put away some if you have a we only want 10 everybody should be there 10 ounces when Cora comes back okay so we have over 10 counters and today Amber we're counting back we are so abstract with today we will be subtracting name that we're going to be losing. so I have 10 counters I gave away one culture how many counters do I stay I need you to put your kitchen counters and then you take up only one only one counter how many counters are left on your table yes London raise your hand and yes London I have I heard wolf I have if you have 10 counters and you take off 189 in carefully put on counters back on your table so I have 10 counters at your alternate on your table you will get this I have 10 counters on night table and I took how many are left on my table results raising their hand and waiting till 10 - 6 go ahead London I want to try it so windy today we work it out we think about it and then we raise our hand there is four there are four I'm on bed for that sound okay Cards Against the first one and then Laura gets the second one so let's go ahead and do okay so there you have it let's see who can get this one and remember you must follow the virtual classrooms of raising your hand and we all your turn will be passed to someone else put your hands down because we have not asked a question as yet so let's go to our question so Chen - 7 is equal to how many counters did you take off are left on your table what's the difference between 10 and 7 can you see who has not want London make sure you have done it before you raise their heads Ed London put your turn counters on the table London and take a go ahead quora you have free you have free friends awesome fun and remember to do the problem remember we're not racing okay we just want the answer that's all so take your time and do your best and come up with the so let's go again let's do another one is fine I have my son is going to be so easy away five what is my dead friends we'll get this 9th and Sligh do you like different and I'm not going to go ahead and close so great job boys and girls go ahead quora when is lunch time
