hello boys and girls steps word problem we got to look at this standard soft two step word problems using the four operations vocab operation mathematical process such as addition subtraction multiplication or Division and equation which is a mathematical statement that uses an equal sign show that two expressions have the same value with our two step word problems but here we're going to continue to use the t-chart also going to pick up the step word problems okay and then we're also going to use a graphic organizer and we'll talk more about that you'll see the graphic organizer and in this impatient now starting with Q we have here see is to Circle important numbers and labels so when you have your word problem you Circle the word the numbers and the labels that you're going to use then you have to underline the question so you need to underline your question this is similar to the unravel that we did here we have B U-Box the operation Clues the words that tell you what I paration to perform you need to buy then we have examined the question down here we have some questions that will help to solve this problem what label will your answer have if you're talkin about marbles if you're talkin about calories which we going to talk about those of your life then what information do you have and last what information do I need to solve the problem and then ask Sonic and do it step-by-step and that's where your graphic organizer I'm going to start first with a one step word problem just to get back into solving word problems Gary ate a burger and fries for lunch and had a cookie for dessert is burger and fries had a total of 1098 calories and he had a total of 5 how many calories how many calories did Gary eat in Lake Circle 2098 calories + 530 calories underline the question we're underline the question box operation Clues how many how many Tails does what did we have what are label calories on your label we knows if he ate 1098 and 530 for lunch so we need to combine our problem here's a graphic organizer and to do graphic organizer all you need to do is put a big plus sign on your notebook paper you can write numbers and operations model equation and an the only answer there are two things you must have and they are underlined in red right here to solve this problem I did what and therefore and this helps us when we are writing our answers in math we have to write them out then this helps you to do that you also need to know how to set up your equations okay. two step word problems you would use your teeth are here we know we have a burger and fries that 1098 calories is cookie with 530 calories so what operation are we going to use the we have how many how many ads so we put adhere fries that are $1,098 cookie that's 530 calories we set up our equation 1098 + 530 + 1628 calories that Gary ate for lunch how to solve this problem I added the calories in both item pH Adam Adam together therefore I know that Gary a1600 28 calories for lunch now you've answered the questions for this word problem now we're going to move into the two step word problem I like I told you you continue to use your T-shirt and here is where you would use your speech are now as the first two we're going to go through and talk about them and then the last one we're going to do together word problems with 340 calories for breakfast then Marcus had a bag of chips and apple and a turkey sandwich for lunch the chips had 190 calories the Apple Head 85 calories and the turkey sandwich had 265 calories if the average person is supposed to eat 2000 calories per day can you set one more calories should he eat today now Circle important numbers in labels we've circled 340 190 85 255 send 2000 calorie important numbers that we're going to need to solve the problem underline the question how many more calories should he eat today to have the 200 that the average person eat box operation how many more now we look at our labels we have calories life is going to be can we have our number Circle and we know that we need to find out how many more calories he needs to eat numbers and operations start here we have Step 1 we know that we're going to have to add the three things he ate here 190 + 85 + 255 to get the total number of calories we're going to take that and add it to the muffin that he ate for breakfast remember so we're adding here and step one now we bring our total go to step two thousand calories - whatever I totally isn't step one to find out more calories that Marcus things to eat Marcus he had 340 calories for his muffin is turkey sandwich with 255 calories 90 calories + 85 calories total we add these together and you put it in the this box here we subtract and that will give us the number of calories that Marcus needs to eat to have the mm for the day your equation we start here 2000 track 3:40 then we subtract 190 + 85 + 255 + 10 parentheses now what do we do when we have something in Peru we already know that we do the parentheses first so we would keep 2000 - 340 - and then we need to add these three together and put that in here and then work the problem always do parentheses first to solve the problem I added 100 190 + 85 + 255 +. Whatever your total is net I added 342 the total now that's the first part that step one I'm going to say then I'll subtracted the number of calories Marcus age from the total he should eat okay there for I know that Marcus needs to eat how many more calories today step word problem you have what you do decide in the first step beer and the second step and last your answer look at this next one is 145 Marvel 33 marbles are green and 57 are blue the rest of the marbles are red how many red marbles does Alex have a right circular important numbers and label we've circled 145 because that's how 33 dreams 57 flu a question how many red marbles does Alex have right now we live down here what did I do Marvel red marbles because that's what we're looking for a red marbles then what do I have you know the green you know the blue and you know the total you're looking the red so that's what you need to find okay now we're going to solve the problem Step 1 first we need to add the green and the blue marbles together once we add those remember we bring it up to step 2 we have our total of 145 more do we have the blue and the green together here once we subtract he has 33 green marble he has 57 blue marbles and we going to add those and that gives us the number of green and blue marbles together we're going to take the 145 marbles subtract the green and blue marbles from one 45 oz how many red marbles we have 33 + 57 + something what was 145 to solve the problem what do we do okay just tell me what we do we need ship added to green and blue marbles Ben Affleck Chucky the total of green and blue marbles from 145 I got that answer here therefore I know that Alex has how many red marbles Quest can I go back and look through the video look through it and see if you have a problem look and see what you did or what you need to look at more closely now you're going to complete one here we go are we looking at mr. Atkins mr. Atkins had two packages 6 battery uses for of the batteries and it's flashlight how many batteries does he have left all right Circle important numbers in labels package has six batteries in each package for packet for Batteries okay underlying the question how many batteries does he have left now box you keep your keywords how many left we need to know how many he has left after he uses for now what are we going to do first do we have our number two packages with six batteries in each package okay so the first thing we need to do is step one we need to multiply time 6 so we multiply then we bring I answer a product of two step two two time 12 * 12 - 4 we're going to subtract because he uses for of the back now that's okay we have Mr Atkins extracting fear he has two packs of batteries okay to pack pack has 6 so we can * 2 * 620 * 6 which is the same thing as 6 + 6 because multiplication remember is repeated addition so he has 12 battery subtract before he used from the 12. Quest alright our equation is going to be 2 * 6 - 4 answer the problem x 2 x 6 to get a total of 12 battery the four batteries from the 12 he had therefore I know that mr. Atkins has how many batteries left 12 take away 4 he has eight batteries left lesson play the word problems on pages 130 and 133 in your instruction book I believe they are the green pages so you take those word problem I want you to draw be a graphic organizer operation your model equation and your answer remember in your answer you have to use those underlined part okay drawing complete the graphic organizer for each word problem on your notebook paper draw you a square big square and put a plus sign in it divided into 4 equal parts label each part and then complete after you do on your word problem do you need additional practice look at your instruction book on pages 140 and 141
