00:00Hello kids, today I want to tell you a story about my friends, the Silly Rollers.
00:08The Silly Rollers lived on a mountain with their entire village.
00:12The name of the mountain was Math Mountain.
00:17Every day they go to play and some of them roll down one side of the mountain while the
00:21rest roll down the other side of the mountain.
00:26This right here is the family of six rollers and they each go out to play rolling down
00:30the mountain.
00:33Wait a minute, some of them went down one side, but how many went down the other side?
00:37I would like to know how many went down the other side.
00:41Well, we can find out by counting the rollers on this side.
00:46We have one, two, three, four.
00:49This means that the rest of the family is playing on the other side of the mountain.
00:53Can you tell me, how many are playing on the right side of the mountain?
01:00If there are six total that would mean there are one, two, three, four, five, six rollers.
01:08There are two rollers on the right side of the mountain.
01:10Great job!
01:12So within this family of six rollers there are four on this side and two on this side
01:16of the mountain.
01:18Can you see a pattern here?
01:20At the top of the mountain we always have the total, which in this case is the entire
01:25roller family.
01:26On the bottom we have two sides of the mountain and each side added together gives us the
01:31total up top.
01:33Each of these sides are called partners.
01:36Both partners added together give us the total.
01:38Wow, this is amazing stuff, I love it!
01:45Here we have a new roller family from the village and there are seven in all.
01:48That means seven is the total.
01:53Three rollers went down the left side of the mountain.
01:56Can you tell me how many rollers went down the right side?
02:03If you said four you are correct.
02:07We have one, two, three, four, five, six, seven.
02:15Seven rollers in all with three on the left side and four on the right side of the mountain.
02:19The partners three and four added together give us the total of seven.
02:24Great job guys, you are amazing!
02:26We can again see that the two partners on the bottom added together make up the total
02:31on the top of the mountain.
02:34Thanks so much for your help.
02:36Keep practicing and learning more.
02:37I'm going to go visit the Math Mountain myself.
02:40We'll see you next time.
02:41Goodbye!
