subtraction 4 digits

Once upon a time, there was a farmer who had 20 sheep. One day, 8 sheep got lost. We can write this as a subtraction story: 20 - 8. To find out how many sheep are left, we start with 20 and take away 8. We can break 20 into 10 and 10, and 8 into 5 and 3. First, take away 5 from one of the 10s, we get 5 left in that part. Then take away 3 from the other 10, we get 7 left in that part. So in total, there are 12 sheep left.

A fanfic about significant digits could be a story that somehow involves the concept of significant digits in a creative way. For example, it might be a science - fiction story where accurate measurements using significant digits are crucial for some kind of space travel or high - tech experiment. Maybe the characters are scientists or engineers who have to deal with the implications of significant digits in their work.

It makes subtraction more interesting. Instead of just looking at numbers, students get to engage with a story, which is more fun. For example, a story about sharing toys can show subtraction in a natural way.

I had 50 dollars. I spent 20 dollars on a book. So the subtraction story is 50 - 20 = 30. I have 30 dollars left.

Well, significant digits fanfiction could be about stories created by fans that somehow involve the concept of significant digits. Maybe it's in a scientific or mathematical setting where characters are dealing with precision and significant figures in a really creative way. For example, a story where a scientist is trying to solve a mystery that depends on accurately interpreting data with the right number of significant digits.

There were 12 apples on a tree. A little boy climbed the tree and picked 5 apples. So there were 12 - 5 = 7 apples left on the tree. Then his sister came and brought 3 more apples she had found elsewhere. So in the end, there were 7 + 3 = 10 apples in total.

You can start by using real-life examples. Like, if you have five apples and eat two, how many are left? That makes it relatable and easier for kids to understand.

You can do both. For small, simple numbers like one, two, three, it often looks better written as words. But for larger numbers or if it's something like a specific address number, digits might be more appropriate. For example, 'There were three apples on the table' reads well, but 'The house number was 123' is more common as digits.

In a 2nd grade math story for subtraction, if it says 'There were 7 cookies and John ate 3 of them.' Then you subtract 3 from 7. 7 - 3 = 4, so there are 4 cookies left.
