00:00Hello, boys and girls. How are you doing today?
00:05Great! I am here with my pet dinosaur, Rexy, to learn about word problems and addition.
00:12I have a problem that I could use your help with. Will you help me?
00:18Thank you so much. Let's go over and take a look.
00:21Rexy, please don't eat the slide. Rexy, down boy, down.
00:26Oh, man. Not again.
00:30Word problems are just math problems that tell a story.
00:34So today, we're going to read a story with a math problem
00:37and see if we can find some different ways to show the problem.
00:41This is our problem, and it says,
00:44Three people go to a picnic in cars.
00:46Two more people go to the picnic on bikes.
00:49There are five people all together at the picnic.
00:52Now, I was told it is always a good idea to read it twice
00:55to make sure I understand what is going on in the story.
00:58Let's read it again.
01:00Three people go to a picnic in cars.
01:02Two more people go to the picnic on bikes.
01:05There are five people all together at the picnic.
01:09I need to make a math equation from this,
01:11but first, let's see if we can draw a picture that goes with this math problem.
01:17It says there were three people that went to the picnic in cars.
01:21Now, I do not have time to draw people, but there is a way to make it shorter.
01:25We are going to use circle drawings because it will go much faster.
01:30I am going to draw three circles for the three people who went to the picnic in cars.
01:36Then it tells us that two more people went to the picnic on bikes.
01:41I am going to put a break apart line right here
01:43to separate the people who went in cars from the people who went in bikes.
01:49There were two people who went on bikes, so we have two circles for those people.
01:55Now we have a picture that tells us a little bit about the story.
01:58We have the three circles on the left that show three people went in cars,
02:02and on the right we have the two circles showing the people who went on bikes.
02:06If I count each one of these,
02:08I will find out that there were five people in all who went to the picnic.
02:12One, two, three, four, five.
02:16I believe that is correct, but I need to write a math equation
02:19that goes with my word problem and my picture.
02:22If you do not know already, an equation is a math sentence,
02:26so let's go ahead and write an equation.
02:29We had three people who went to the picnic in cars,
02:32and we had two people that went on bikes.
02:35I want to know how many there are together,
02:37so I will put a plus sign in the middle to add these together.
02:42I will also put an equal sign,
02:44because all good math sentences usually have an equal sign.
02:48So if I add these together,
02:50I know that there are five people who went to the picnic.
02:54Here is our equation.
02:56Three plus two equals five.
02:58Great job, kids!
03:00If you look, you can see that I have words that tell the story,
03:03I have a picture that tells the story,
03:05and now I have numbers or an equation that tells the story for this problem.
03:10I wonder if there is another way I can illustrate or show this problem.
03:14I know! What if we did a math mountain?
03:19Here is a math mountain,
03:21and if you remember, the total always goes on top of the mountain.
03:25What is the total amount of people who went to the picnic?
03:30Five! Great job, guys!
03:33The partners or the bottom parts of the mountain will be what numbers?
03:39The three and two are the partners at the bottom of the mountain.
03:43Great job again!
03:45And we already know if we add the partners together, we get the total.
03:48Awesome job, guys!
03:53Wow, guys, look at this.
03:55We now have three different ways of showing the word problem.
03:58We have a circle drawing, we have an equation with numbers,
04:01and we also have a math mountain.
04:03This is awesome!
04:05I'm going to use these methods to help me figure out other word problems.
04:11Thanks for helping me today, and we will see you later. Goodbye!
04:15Slow down, Rexy! Slow down! Whoa! Down, boy! Whoa!
