hey bear it is subtraction Monday we're starting subtraction and we just finished up for can Edition most of us have began to feel comfortable with it using our fingers. Pictures using manipulate and we are able to perform at an independent level we are now moving into the next topic which is subtraction subtraction uses the words take away or left minus subtract and so forth section on day one we're starting out with just a little bit of concept-development we're working on building up some of those skills that we need to lay down as a foundation so that we can build on top of as we go through subtraction and we start to work a little more explicitly so in your homework assignment for today I opened PDF file that I have on my school website as well as on Class Dojo and this PDF files subtraction so I'm going to go to subtraction day one because it is day one it is so there it is subtraction day one and I'm going to scroll down for subtraction day 1 you need a paper or a whiteboard either will work a pencil dry erase markers if you don't have not a deal-breaker and refined cross it out scribbled out or child try again or mental math with the screen a lot of this math is very visual so you could easily use a screen in either cover things up or point at things account right okay so as I mentioned it is I am at a loss of words are guys not used in movie making so much it is our task to build knowledge so that we can better build upon those building blocks for subtraction so I said building number sense with continued practice in one-to-one correspondence while counting touching each object as you count one to one correspondences When you're counting and you touch each object that you see as you count one to one is linked pretty heavily or strongly to number sense because if you're not touching or able to see each thing counting are going to count it wrong so often your number sense could be a little bit skuter off if you're not able to touch an individual account each object okay subtraction problem simple visual how many snails are in the park so your kid is going to look at the picture of these lovely cute little snails that was Potter found in the wonderful web and they're just going to count they can count it two ways they can count on their hands with their fingers or they can count on the screen where they're poking each snail in the picture either way is fine the important part is that they're able to pick out the snake and get the correct answer and I'm not going to give you the answer cuz I want you to be able to work there fees with your kiddos and I don't want to be a spoiler in case they're watching with you never one they are counting the snails they're going to give point couch they can count on their whiteboard by doing Talley's Pikachu. Or they can just catch and write the number on their whiteboard or their piece of paper number to we are still counting like it said that first slide were building fluency were building knowledge we are still counting we're working on that went to once your child might look at this picture and say that's the same one I just did that there are however many they counted from the first flight but they'll have to look carefully because there might be one or two missing same thing they're going to either count on their paper or whiteboard using tallies ducks they can write their numbers as they're counting or they can just write the number that they counted they can do the mental math way which is with the screen or your kind of looking at the screen in your accounting and it on your you show how many you counted easy-peasy number 3 no surprise there another counting problem how many snails are in the park it's like we've done this before same thing those tallies dots that Mental Math you are just counting if your child is struggling with coming up with the correct answer I would advise that you physically take their finger and point to each state in the picture until they are able to do so independently number for Ono the same type of problem again it's almost like repetition works really well little kids safety you're counting visually this wasn't easy cuz I can look and I can see you how many years snails are easily visible to my eye and how many are covered up number 5 this one looks like I'm trying to trick you up because you may not see me smells but that's important to because learning the difference between something and nothing and the number associated with nothing 0 is an important task for kids because 0 is an important part of the number since and the number learning process I can't number six is a little bit different now you got a lot more words on your side you got in your corner Reddit you have a little of vocabulary of a little of vocabulary banner and right here the vocabulary Banner that says our less take away as I mentioned when I started the video the words that we use most often with subtraction is we say how many are left take away 3 so you're going to start using those words just to familiarize them with the words associated with subtractions so in this problem it says he's grown up so we can see it all the way this is for snails are in the park and zero snails leave the park what is for snails take away 0 snails how many snails are left so one of the ways I would do this problem and I would do this problems most kids just so late at foundation for subtraction is I would do a picture we would draw a picture to represent the problem so it says for nails are in the park depending on what I meant I might draw this nails if I feel like I can't draw snail I coach the kids into doing a. Because sometimes young children get frustrated when they can't draw the picture as well as you can so on my whiteboard on my piece of pie my scratch paper I'm going to scribble or Draw Ducks right so I would draw one two three four ducks and I'm going to look at the prop it says Forest nails are in the park Forest nails so I'm going to number those Nails in a number 1 2 3 4 from a snail so I know there are four snails a says what is for snails take away 0 snails and I would physically show the action associated with take away what is for snails take away 0 how many snails are left so if a piece of paper or what I have to do is I have to coach them to x out the ones they're taking away so in this case they have therefore. The paper and I would say if we're going to take away 0 how many will be acts out and they're supposed to tell you how many that we X out so if I'm taking away zero I should be texting out zero and then we look back at our after we finished the ex parte and we count how many are left if you don't have access to paper a whiteboard you can do this on your fingers as well right so we know that there are four snails in a park and ran it take away so I'm going to fold any fingers I'm not and I'm going to coach them and looking at their fingers and understanding that is zero means that none of the fingers are going to move so that they can physically count how fingers are left see my next line very similar same vocabulary or working with our left and take away I've got a little bubble tip up here for you it says use your hand to cover up to the snails on the screen or XML on your picture so just like I spoke to before how we ask them out to get rid of him so this one says for snails were in the Grass at the park and when I read the problem to the kids off to call response or comprehension check where I'll read the first sentence I'll say for snails for the grass of the park how many sales were in the Grass at the park and the kids should be able to tell me there grass of the park Forest nails when the grass at the park into snails left to go to the Pont how many snails were left what is 4 take away 2 same thing we can do paper and whiteboard so that we could draw a picture which is the ideal way of doing and that's the way I would do it in the classroom but if you don't have those resources you can easily use the computer screen and cover or you can use your fingers right so if I was to use the computer screen I would just take my hand and I would lay my fingers over the ones that I'm taking away so if I'm taking away to a cover-up to smells so that your physically see how many snails are left if I'm not using the computer screen if I'm using my fingers I'm going to first count how many snails so I know how many fingers to hold so I can account pointing at the and I'm going to have to each nail on the screen by Touch 1 2 3 4 and I'm going to have them count it again just in case to make sure one two three four and then they hold up there one two three four fingers there are four snails and four fingers on my hand and then we go back to our problem when we read again we say for snails where the grass at the park how many snails are in the Grass at the park for two snails left to go to the pond how many snails left to go to the pond so we need to take away two write me to take away two so look at your fingers and you're going to fold or take away two fingers so let's take away the little one so there's one two and then I count how many are left 124 take away two is one too so that's the way I would do it with my fingers or a great idea you'll have that white border that paper just cuz that's the best practice to get into is drawing a picture of the equation working out the math problem so on your paper on your whiteboard you can either do pictures of the snail so if your child is an artist and I want to draw the snails that can draw the four snails if your child is a perfectionist and gets really frustrated when they can't draw something perfectly as of new 4.44 Tally's to represent those nails call that using symbols for representation and then you're going to have them go ahead and urine has an X Out the two snails that went to the pond don't erase them because they should be able to see them see that they're taking them away out the to that the pain I've been having count on their paper how many are left that is the end of day one so that's all we're working on day one we're just building that knowledge preparing them for doing more sophisticated subtraction where they're actually writing out the equations with the numbers and then eventually solve it nice job thanks for watching my little video here and I will try again tomorrow for the next day
