Oh hi everybody! Today I’m going to talk to you about numbers, and data,
and maybe even bugs. Ho, I really like bugs.
So one thing we can use numbers with is... data! DATA! And some people call it data. DATA!
Anyway, data is when you collect,
and sort information, and try and understand things like facts about something. For example,
here is some data about me: I have one mouth, two eyes, and 17 brothers and sisters!
Oh hi everybody!
OK so, we can collect data and understand things in different ways. One way
is to use our eyes and look. We call this observing. OBSERVING!
For example, I wa- hey, who is talking? Francis and August, please be quiet!
OK. As I was saying: I want to observe my brothers and sisters and collect data
about what color they are. Do you want to help me? OK great! We can use a chart and write down the numbers beside
the words of the color, up here. First up is purple. So, how many brothers and sisters are purple?
Let’s count. One, two, three, four, five, six. Six! Hey do you know what these are?
These are tally marks. TALLY MARKS! Tally marks are like a way of counting using special lines.
When we count with tally marks we make one up and down line for each number, up to four, like this,
and then when we get to five we make a side to side line through, like this. And now we know
we have a group of five. But after five, well then we then start over again and make a new group.
So when we count up to six, this is how we do it with tally marks. One, two, three, four, five,
and six. OK, moving on, the next color is green. How many brothers and sisters are green?
Let’s count. One, two, three, four. Four! And finally, how many brothers and sisters
are blue? Let’s count. One, two, three, four, five, six, seven. Seven! Good job everybody,
we have now collected all the data about the color of my brothers and sisters. Yay!
OK, you’ve done such a good job, it is now time to take a stretching break…
Oh... ya... OK that's enough!
So, we just saw that we can collect data and understand things by observing with our eyes,
but did you know that we can also collect data
and understand things by asking questions with our voice?
Oh yes we can! OK, let’s ask my brothers and sisters some questions and collect their
answers with tally marks. OK what should we ask them about? Hmmm... oh I know, bugs! I said bugs!
OK, there are three different kinds of bugs here:
spider, ladybug, and butterfly. I want to know which bug they like the best. So, we just saw th-
hey, who is talking? Oh! Francis and August, you need to separate! Please move!
OK that’s better. Now, brothers and sisters, I want you to raise your hand when I say the name
of the bug that you like the best. And remember you can only choose one bug and raise your hand
one time. OK, please raise your hand if you like spiders the Best. Let’s count. One, two,
three. So three brothers and sisters like spiders the best. Now raise your hand if you like
ladybugs the best. Let’s count. One, two, three, four, five.
So five brothers and sisters like ladybugs the best. Now raise your hand if you like butterflies the best.
Let’s count. One, two, three, four, five, six, seven, eight, nine.
So nine brothers and sisters like butterflies the best. Wow!
Great data collecting everyone! Now let’s take a break and do some stretching. Oh.
Yah. Feels good OK that's enough!
Now let us show this data in a different way.
Instead of using tally marks, we will take the numbers and put them into something we call a
pictograph. PICTOGRAPH! A pictograph is a way to show data with pictures.
OK, so remember, how many brothers and sisters liked spider best? That’s right three! One, two,
three. And how many liked ladybug the best? That’s right five! One, two, three, four,
five. And how many liked butterfly the best? That’s right, nine. One, two, three, four,
five, six, seven, eight, nine. And now our pictograph is complete.
So, looking at the pictograph data, which bug do most of my brothers and sisters like the best?
That’s right, it’s butterfly! Yay! There are more butterfly pictures than anything else,
so we have learned that among my brothers and sisters, the most popular bug is the butterfly!
And which bug is the second most popular bug? That’s right, it is ladybug! Yay!
Oh, here’s a question: How many more ladybugs would we need to have in order to equal
the amount of butterflies? If you said four you are right. Yay!
And finally, what is the third most popular bug, or we can also say: the least popular bug?
That’s right, it is spider! It’s OK spider, I still like you.
OK, that is all the time today we have for data. And don’t forget to subscribe to our channel for more
laughing and learning from Scratch Garden. Did you know that we have many other videos with bugs?
No it’s true! Maybe you should ‘bug’ your teacher to play some! Ha! OK bye for now.
