2. Sally’s Day at the Farm
CCSS.Math.Content.1.OA.A.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from,
putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for
the unknown number to represent the problem.1
CCSS.ELA-Literacy.SL.1.1a Follow agreed-upon rules for discussions (e.g., listening to others with care, speaking one at a time about the topics
and texts under discussion).
3. Sally loved helping her
Grandfather with the
animals on the farm. Sally
was thrilled when her
grandfather asked her to
come over to assist him.
Sally arrived at sunrise and
saw her grandfather
waiting for her by the barn.
She heard the sound of the
rooster cock-a-doodling to
welcome the new day. Her
grandfather smiled and
said, “Good morning, Sally,
I’m so glad to have a helper
today.”
Have you ever visited a farm? What animals might live on a farm? Turn and talk to your partner.
4. First, Sally and her grandfather
visited the chicken coop to
collect fresh eggs. Grandfather
said, “Let me show you how we
collect the eggs.” Sally’s
grandfather showed her to
gently reach under the hens to
collect the eggs. Sally placed all
the eggs she collected in a
basket. Grandfather said, “I see
you have collected 12 eggs! I
collected 10 eggs.”
I wonder how many eggs they collected together. Let’s use a problem solving strategy to find out.
Draw a picture in your journal to show how many eggs Grandfather collected and how many eggs Sally
collected. How many eggs did they collect together? Discuss your answer with your math partner. Write
a number sentence to show how many eggs were collected.
5. How many eggs did they collect altogether?
Move the eggs from each basket to find the total number of
eggs collected.
Sally’s Basket
Grandfather’s Basket
______ Sally’s eggs + ______ Grandfather’s eggs = _______ total number of eggs
6. “Thank you for helping
collect eggs. It’s time to
go milk the cows,” said
Grandfather. “Hooray,”
said Sally, “I love cows!”
Sally collected 8 gallons
of milk. Grandfather also
milked cows. Together
they collected 15 gallons
of milk. How many
gallons of milk did
Grandfather collect?
One Gallon
I wonder how many gallons Grandfather collected. How could I find this out? Turn and discuss
this with your math partner.
7. How many gallons of milk did Grandfather collect?
Drag the milk gallons to find out how many gallons
Grandfather collected.
Grandfather’s Gallons
Sally’s Gallons
Total Gallons
8
Sally’s Gallons + ______ Grandfather’s Gallons =
15 Total Gallons
8. “I bet the lambs are hungry,”
said Grandfather. “Let’s get
the buckets of grain ready.”
Sally was excited to feed the
baby sheep. The lambs, Lucy
and Ebony, were indeed
hungry. Altogether, they ate
13 small buckets of grain.
Sally fed Ebony 7 buckets of
grain. Grandfather fed Lucy.
Sally wondered how many
buckets of grain Lucy ate.
How could Sally find out how
many buckets of grain Lucy
ate?
Lucy
I am wondering if we could use manipulatives to help us to figure this out. Discuss with your partner a strategy you could use
to find out how many buckets of grain Lucy ate. Use manipulatives with your math partner. We will come back to the group
and share our strategies. Record a subtraction sentence for the story in your math journal.
Ebony
9. Lucy
Ebony
____ - ____ = ____
Altogether, Lucy and
Ebony ate 13 buckets of
grain. If Ebony ate 7
buckets of grain, how
many buckets of grain did
Lucy eat?
10. “I have a surprise for you
Sally. We have newborn
piglets,” said Grandfather.
“Let’s go see them!” said
Sally. On the way to the
pigsty, Sally saw Louise
the Pig wearing her green
rubber boots that
Grandfather bought for
her. Grandfather really
likes his pigs to have
clean feet.
What do you think a pigsty is? Discuss this with your partner.
11. Grandfather wants to buy
boots for all the newborn
piglets. Three piglets
were in the litter. How
many pairs of boots does
Grandfather need to
purchase?
How many boots are in a pair? Draw 3 piglets in your math journal to help you determine how
many pairs of boots Grandfather needs to purchase for each piglet to have boots.
12. How many pairs of boots does Grandfather need to
buy? Hint: Drag the boots needed for each pig into
the boxes.
How many boots are needed altogether? How many pairs are needed? How do you
know? Discuss with your math partner.
13. “I am glad to know that I
need to buy 6 pairs of
boots for my piglets. I
could not have done this
without you, Sally,” said
Grandfather. “I love
helping you on the farm,
Grandfather,” said Sally.
“I think I hear Grandma
ringing the dinner bell,”
said Grandfather.
“Working on the farm
really makes me hungry!”
said Sally.
