hygiene boys and girls and welcome back to an exciting summer learning this week we're going to be remembered rapidvideo to take your time super hard and any questions you have we will answer to school set all right welcome to 2 lesson 24 ATMs in at 1 your vocabulary for this week are 10 + 1 the strategies we will be focusing on this we are tens and ones Mental Math which is basically being able to add the numbers in our heads according to the number facts that we learned and decomposing decomposing taking one number and divided into two different aliens finding the to the aliens that equal to a specific number take the time now if you need to to make sure you have a pencil paper and your i-Ready Math workbooks guided practice problem that we will first be focusing on starts on page 157 and the problem is finding 32 + 21 let's work it out for this man from what we can do is start with our numbers put in the correct place setting right now what's 3 + 2 1 then I'm going to take the number 21 and do it the same way because 21 is actually 2:10 or two groups of 10 and one one I was sending this up what it does is it allows you and I what is the add the numbers according to their place back together once again so what we start off doing is 3 + 223 + 2 is 5 so we have five cans and all three 10 + 210 5:10 and we have to 1 Play Beautiful is 312 + 1 is 3 so now we have 5 tens and 3 ones before I continue I know that a lot of you are used to seeing this sit up this way and maybe you're not used to going from right to know that I going left to right because we were going to start adding with regrouping but eventually we worked out together that if we know the number of tens and ones that we know how use group we won't necessarily have to go from left to right we're going to start by using the same the numbers and we divide them according to the number 18 and 6 form so I'll write the number as 210 Phoenix wand there are three 32 10th Place 310 wants course the same person who won the 10th race in the ones place but you probably remember when we did this we started from the left and to the right you can still use this strategy the only thing about whether you go right to left or left to right is understanding how a group of 10 works and I will explain it to you once you get there but right now I'm going to the strategy of the book instruction for your teacher Furniture I can help you out with that so continue on solving we're going to stop and add our 10 worst so two tens and three more 10 give me five tens and all and two ones together my answer is 5 tens and 8 ones and we know that 5 tens and 8 ones can also be represented as the number 858 here's another guided practice question page 159 is where you can find how many shells are there for this problem the same kind of strategy will apply but I'm just going to focus in on some other things that I want you guys to be aware of or that I want to remind you about as we go through so first I book has already set up where are tender representar one represented sometimes you may get to a problem how many children were actually were 13 and 14 which is where your math problem comes from 13 + 14 from Ashley did what started by doing something called decomposing decomposing is one of your vocabulary words that mean to take a number depart basically I'm find the two atoms that make up that number so this is also where are number bonds come from on the page because it took the number 13 from your number sentence a decomposing number in 210-3214 from a number sentence and decomposer a lot easier to add those numbers together so as you can see here as those numbers to line them up according to the tens and the one easier put the Channel 3 weather we go down and we saw we add according to the tens in the morning so 1010 gives us 20 + 3 + 4 give us a as you can see on your workbook page so now I got to figure out what is 20 + 7 you can think of this as 20 and 7 more than your teachers have drilled those 10 number in 2002 as a part of your mental man the more you practice the better you will get 20 + 720 + 7 * 20 + 7 more which is just adding seven more to 20 with us to the number 27 and of course like if you still having trouble with that for right now use that mental mental math imagine starting a swing and counted onzas on seven more and imagine what that number is and that will help you get your so 13 + 14 is 27 Simon says we are as follows in your back instruction 159 talk about addiction instructional workbook page 100 number 1 through 2 iradimed instructional workbook page 161 numbers 3 through 5 awesome awesome.
