5. 11 3 8 8 more hair bows
Materials: Counters, 18 for each child
1. Say: Alicia had 12 crayons. Have children show 12 counters in a row and write 12. Say: Max had 5
crayons. Have children show 5 counters in a row below Alicia’s and write 5. Say: How many more
crayons did Alicia have than Max? Have children remove 1 counter from each row at the same
time. Have them continue removing pairs until all the counters in the top row are gone. Have children
complete the number sentence by writing 7.
2. Say: Jaden had 16 grapes. Have children show 16 counters in a row and write 16. Say: Rafel had
8 grapes. Have children show 8 counters in a row below Jaden’s and write 8. Say: How many more
grapes did Jaden have than Max? Have children remove 1 counter from each row at the same
time. Have them continue removing pairs until all the counters in the top row are gone. Have children
complete the number sentence by writing 8.
3. Say: Vero had 14 apples and 5 oranges. How many more apples than oranges did she have? Have
children use counters to write and solve the number sentence.
4. Say: Miles had 15 fish. Olivia had 6 fish. How many more fish did Miles have than Olivia? Have
children use counters to write and solve the number sentence.
5. Say: Poppy had 11 hair bows. Lora had 3 hair bows. How many more hair bows did Poppy have
than Lora? Have children use counters to write and solve the number sentence.
Stories about Comparing (continued)
Draw a picture to find the differences.
Then write a subtraction sentence.
6. 11 dogs are in a pen.

cat. How many more
dogs are in the pen?

Ongoing Assessment
Observe that children are taking away the counters
in pairs, not all from one row. Make sure they
understand that they are finding how many more
counters are in one row than in the other.
Error Intervention
If children have trouble writing number sentences
for the comparing stories,
then use B18: Comparing Stories.
If You Have More Time
Have two different size groups of children come to
the front of the class and line up in two rows, one
group in each row. Have children in their seats write
a number sentence for how many more children
are in one group than another. Then, have one child
from each group sit down. Continue until there are
no children left in the smaller group. Have children
count the remaining children to check their number
sentences.
