Spark Your Learning
How can making an addend a ten help you find how many children are playing soccer?
Read the following: There are 27 second graders and 16 third graders playing soccer. How many children are playing soccer? Make a concrete model or draw to show the problem.
Answer:
There are 43 children playing soocer,
Explanation:
Given there are 27 second graders and
16 third graders playing soccer I break 16 apart an
addend to make the next tens number as 3 and 13,
so that 27 + 3 becomes next tens number,
27 + 16 ,
27 + 3 +13,
30 + 13 = 43 therefore 43 children are playing soocer.

Question 1.
Timothy has 37 red apples and 17 green apples.
How many apples does he have?
A. How can you draw to show the problem?
Answer:
Explantion:
By using Timothy has 37 red apples and 17 green apples
drawn to show the problem.
B. Use your drawing to show how to get to the next tens number.
Answer:
Breaking 17 apart gets the next tens number,
Explanation:
Breaking 17 apart as 3 and 14 gets an addend to
the next tens number for 37.
C. How many do you have to add to 37 to make the next tens number?
Answer:
3,
Explanation:
By adding 3 to 37 to make the next tens number.
D. How can you complete each equation to solve the problem?
Answer:
Explanation:
Given Timothy has 37 red apples and 17 green apples,
I break 17 apart an addend to make the next tens number as
3 and 14, so that 37 + 3 becomes next tens number,
37 + 3 + 14,
40 + 14 = 54.
E. Solve.
Timothy has ___54_____ apples.
Answer:
Timothy has 54 apples,
Explanation:
Given Timothy has 37 red apples and 17 green apples,
I break 17 apart an addend to make the next tens number as
3 and 14, so that 37 + 3 becomes next tens number,
37 + 3 + 14,
40 + 14 = 54, therefore Timothy has 54 apples.
Turn and Talk How does drawing help you find the next tens number? Explain.
Answer:
Drawing helps to easily identify the next tens number,
Explanation:
In drawing we can easily decompose one of the
addends to make a ten from the other which helps
us to find the next tens number.
Question 2.
Sam has 28 books. Kyle has 16 books. How many books do they have?
A. How can you draw to show the problem?
Answer:
Using Sam has 28 books and Kyle has 16 books,
Explanation:
Using the given data Sam has 28 books and
Kyle has 16 books we can draw to show the problem.
B. How can you complete each equation to solve the problem?
Answer:
Explanation:
Completed the equation
28 +16,
28 + 2 + 14,
30 + 14 = 44.
C. Solve.
They have ___44____ books.
Answer:
Sam and Kyle have 44 books,
Explanation:
Given Sam has 28 books and Kyle has 16 books,
I break 16 apart an addend to make the next tens number as
2 and 14, so that 28 + 2 becomes next tens number,
28 + 16,
28 + 2 + 14,
30 + 14 = 44, therefore Sam and Kyle have 44 books.

Question 1.
Zoe has 29 red beads and 22 blue beads.
How many beads does Zoe have?
Draw to show the problem. Complete each equation to solve.
___51_____ beads
Answer:
Zoe have 51 beads,
Explanation:
Given Zoe has 29 red beads and 22 blue beads,
I break 22 as 1 and 21 apart an addend to make
the next tens number as 29 +22,
29 + 1 + 21,
30 + 21 = 51,Drawn to show the problem above,
Completed each equation and solved,
therefore Zoe have 51 beads.

Question 2.
Use Tools Darnell has 26 pencils. Laila has 19 pencils.
How many pencils do they have? Draw to show how to
make one addend the next tens number.
Complete each equation to solve the problem.
They have ____45_____ pencils.
Answer:
Darnell and Laila has 45 pencils,
Explanation:
Given Darnell has 26 pencils. Laila has 19 pencils.
Drawn to show how to make one addend the
next tens number.
By breaking 19 as 4 and 15 apart an addend to make
the next tens number as 26 +19,
26 + 4 + 15,
30 + 15 = 45,
Completed each equation to solve the problem as
shown above therefore Darnell and Laila has 45 pencils.
Question 3.
Use Structure Make the first addend the next tens number.
Complete each equation to solve.
Answer:
Explanation:
Given 28 + 18, made the first addend the
next tens number by breaking 18 as 28 + 2 + 16,
30 + 16 = 46 solved.
