Page 2: Haley’s Family Farm

My name is Haley. I live on a farm. In the spring, a lot of the animals give birth to babies. I help my dad and mom count the new babies. We use fractions on our farm to compare how many animals we had originally to how many animals we have after spring births and how many we sell and have left after some are sold.

Page 3: Haley’s Family Farm

On our farm, we originally had four cows.

Page 4: Haley’s Family Farm

In the spring, the cows give birth to calves. This spring, three cows gave birth to one calf each, but one cow gave birth to two calves. Will you help me count the total number of calves?

There are 5 calves total.

There are 4 cows total, 1 of the 4 cows gave birth to 2 calves. The fraction can be written two ways, with numbers 1/4 or with letters

one-fourth.

Page 6: Haley’s Family Farm

We can rearrange the cows to look like the fraction 1/4.

The bottom of a fraction is called the denominator. Since

there are 4 cows total, they all belong in the

denominator.

The top of a fraction is called the numerator. In this fraction, the numerator represents the 1

cow that had 2 calves.

What fraction of the 5 horses gave birth to two colts?

1 23

Three of the five horses gave birth to 2 colts each. We write this as a fraction 3/5 or three-fifths.

Page 21: Haley’s Family Farm

What fraction of the 5 horses gave birth to one colt?

1 23

4 5

Two of the five horses gave birth to 1 colt each. We write this as a fraction 2/5 or two-fifths.

We have 8 colts. Dad plans on selling 6 of the eight colts. We write this fraction

6/8 or six-eighths.

Page 24: Haley’s Family Farm

When the colts reach 6 months old, Dad plans to sell 6 of the colts. What fraction of the colts is dad planning to keep?

1 2 3

4 5

We have 8 colts. Dad plans on selling 6 of the eight colts. If we subtract 6 from 8 the answer gives us the number of colts dad is planning to keep.

8 – 6 = 2

We write this fraction 2/8 or two-eighths.

On our farm, we have two pigs. In the spring, they give birth to piglets.

Page 26: Haley’s Family Farm

If 2/23 is the fraction of pigs out of the total number of pigs and piglets, how many piglets did the pigs have all together this spring?

21

The denominator of the fraction is 23 and represents the total number of pigs and

piglets. If there are two pigs represented by the numerator 2, then 23 subtract 2 equals

the total number of piglets.

Page 27: Haley’s Family Farm

One pig gave birth to seven piglets and the other pig gave birth to fourteen piglets.

7 + 14 = 21

The total number of piglets equals 21.

Dad will sell 3/4 of piglets after they reach 8 weeks old. How many piglets will dad sell?

Three-fourths of the piglets means dad sold 3 of every 4 piglets.

So we group the piglets into groups of 4.

We have one piglet left over which is 1 of the needed 4 to make another group which is 1/4 or one-fourth.

We have one piglet left over which we give to my uncle He keeps it to take to the state fair.

We now can take away 3 out of each group of 4.

We will keep 5 piglets and the 2 pigs we originally had.

On our farm, we have seven sheep. In the spring, they give birth to lambs.

If the numerator is the number of sheep and the denominator is the number of sheep and lambs, then subtracting the numerator from the denominator gives us the total number lambs the sheep had all together.

There are twenty-two lambs and sheep. Of the 22 sheep and lambs, 8 lambs are planning to be sold. We write this fraction 8/22 or eight-twenty-seconds.

Page 41: Haley’s Family Farm

My cat had 7 kittens. When a cat has kittens, as a group they are called a litter. Of the kittens, 3are white, 2 are yellow, 1 is black, and 1 is brown.

What fraction of the litter are white?

What fraction of the litter are yellow?

What fraction of the litter are black?

What fraction of the litter are brown?

There are 7 kittens. Of the 7 kittens, 3 are white. We write this fraction 3/7 or three-sevenths.

There are 7 kittens. Of the 7 kittens, 1 is brown. We write this fraction 1/7 or one-seventh.

There are 7 kittens. Of the7 kittens, 1 is black. We write this fraction 1/7 or one-seventh.

There are 7 kittens. Of the 7 kittens, 2 are yellow. We write this fraction 2/7 or two-sevenths.

Mother Cat

Page 42: Haley’s Family Farm

There are 7 kittens in the litter. There is 1 mother cat. If we add the mother cat and the litter of kittens. How many cats and kittens do we now have?

1 cat + 7 kittens = 8 total

What fraction of the total are kittens?

What fraction of the total is a mother cat?

Of the total 8, 7 are kittens. We write this fraction 7/8 or seven-eighths.

Of the total 8 cat and kittens, 1 is a mother cat. We write this fraction 1/8 or one-eighth.

Page 43: Haley’s Family Farm

The fraction 1/8 looks like this.

Page 44: Haley’s Family Farm

The fraction 7/8 looks like this.

Page 45: Haley’s Family Farm

When the kittens reach 6 weeks old, I plan to give all the kittens (1 litter) away. What fraction of the kittens am I giving away?

There are 7 kittens total. If I give all the kittens away, I am giving 7 of the 7 away. We write this fraction 7/7, seven-sevenths, or 1 whole litter.

Page 46: Haley’s Family Farm

As with cats and kittens, dogs giving birth to puppies are considered a litter also. How many puppies are in the farm dog’s litter? There are 5 puppies in her litter.

Page 47: Haley’s Family Farm

If we add the mother dog and the litter of puppies, How many do we have in total?

There are 6 all together.

What fraction of the total are puppies?

What fraction of the total is a mother dog?

Of the total 6 dog and puppies, 5 are puppies. As a fraction, we write, 5/6 or five-sixths.

Of the total 6, 1 is a mother dog. As a fraction, we write 1/6 or one-sixth.

Page 48: Haley’s Family Farm

When the puppies reach 6 weeks old, I plan to give 4 of the puppies away. If I give away 4 puppies, what fraction of the puppies am I going to keep?

There are 5 all together. If I give away 4, I am keeping 1 puppy. The 1 puppy written as a fraction is 1/5 or one-fifth of the puppies.

Page 49: Haley’s Family Farm

When the puppies reach 6 weeks old, I plan to give 4 of the puppies away. If I give away 4 puppies, what fraction of the puppies am I going to keep?

If I give away 4, I am keeping 1 puppy. We can rearrange the puppies to look like the fraction 1/5.
