Penguin Problem Solving

Read and solve each of the problems below. Show your work.

  • Use numbers, pictures, or words to help solve the problem.
  • Fill in the missing number in the equation when you find the answer.

Question 1.
Five penguins are on the ice. Six penguins in the water. How many penguins in all?
Bridges in Mathematics Grade 1 Home Connections Unit 6 Module 3 Answer Key 1
5 + 6 = _____________ penguins
Answer:
Number of penguins on ice = 5
Number of penguins on water = 6
Number of penguins in all = ?
= 5 + 6
= 11
Therefore all the number of penguins are 11.

Question 2.
There are 8 penguins on the ice and some more penguins in the water. There are 11 penguins in all. How many penguins are in the water?
Bridges in Mathematics Grade 1 Home Connections Unit 6 Module 3 Answer Key 2
8 + ____________ = 11 penguins
Answer:
Number of penguins on ice = 8
Total number of penguins present = 11
Number of some penguins = x
Equation : 8 + x = 11
x = 11 – 8
= 3
Therefore 3 penguins are on the water.

Question 3.
There are 13 penguins in all. Seven of them are in the water. How many penguins are hiding behind the hill?
Bridges in Mathematics Grade 1 Home Connections Unit 6 Module 3 Answer Key 3
____________ + 7 = 13 penguins
Answer:
Total number of penguins = 13
Number of penguins on water = 7
Number of penguins behind the water = x = ?
Equation : 7 + x = 13
x = 13 – 7
x = 6
Therefore 6 penguins are under the water.

Question 4.
There were 13 penguins standing on the ice. Three dove into the water. How many penguins were left on the ice?
Bridges in Mathematics Grade 1 Home Connections Unit 6 Module 3 Answer Key 4
13 – 3 = ____________ penguins
Answer:
Given,
There were 13 penguins standing on the ice.
Three dove into the water.
13 – 10 = 13
13 – 3 = 13 penguins

Question 5.
There were 12 penguins standing on the ice. Some of the penguins dove into the water. Now there are only 3 penguins left on the ice. How many penguins dove in?
Bridges in Mathematics Grade 1 Home Connections Unit 6 Module 3 Answer Key 5
12 – ____________ = 3 penguins
Answer:
Number of penguins standing on the ice = 12
Number of penguins left on the ice = 3
Number of penguins dove into the water = x = ?
Equation : 12 – x = 3
This implies x = 12 – 3
x = 9
Therefore 9 penguins are dove into water.

Question 6.
CHALLENGE Some penguins were playing on the ice. Ten of them dove into the water. A few seconds later, 6 of those penguins jumped back onto the ice. Now there are 12 penguins on the ice. How many penguins were on the ice to start? Use numbers, pictures, or words to show how you got the answer.
Answer:
Number of penguins dove into the water = 10
Number of penguins jumped back onto the ice = 6
Number of penguins on the ice = 12
Number of penguins on the ice at starting = ?
Equation : x – 10 + 6 = 12
This implies x – 4 = 12
Now 4 on both sides of Equation
x – 4 + 4 = 12 + 4
x – 0 = 16
x = 16
Therefore 16 penguins are there on the ice at starting.

Equations & Fact Practice

Question 1.
Circle T if the equation is true. Circle F if the equation is false.

ex: 10 + 3 = 13
T
F

a. 6 + 6 = 12
T
F
Answer:
True
The given answer is correct since when 6 and 6 are added it generates the value as 12 .

b. 12 = 7 + 5
T
F
Answer:
True
The given answer is correct since when 7 and 5 are added,  it generates the value as 12 .

c. 12 – 8 = 4
T
F
Answer:
False
The given answer is correct since when 8 is subtracted from 12 it generates the value as 4.

d. 10 – 2 = 6
T
F
Answer:
False
The given answer is correct since when 2 is subtracted from 10 it generates the value as 8.

e. 10 = 6 + 4
T
F
Answer:
True
The given answer is correct since when 6 and 4 are added is subtracted it generates the value as 10.

f. 5 + 6 = 6 + 5
T
F
Answer:
True
Given L.H.S = 5 and 6 are added generates the value 11
R.H.S = 6 and 5 are added generates the value 11
Both the sides value are equal , the Given value is True.

g. 11 = 3 + 7
T
F
Answer:
False
When 3 and 7 are added the result must be 10 but not 11.Hence the given condition is false.

Question 2.
Read the story. Circle T if it could be true. Circle F if it must be false.
a. Sara had 8 cars. She got 7 more cars for her birthday. Now she has 15 cars in all.
T
F
Answer:
False
Initially , Number of cars Sara contain = 8
Again , Number of more cars = 7
Then , total number of cars = ?
= 8 + 7
= 15
Hence the given condition is false.

b. Max made 13 cookies. His brother ate all the cookies. Max has 3 cookies left.
T
F
Answer:
False
Number of cookies done by Max = 13
Number of cookies ate by his brother = 13
Number of cookies left = 13 – 13 = 0
Number of cookies left are zero. Hence the given condition is false.

Question 3.
Read the story. Circle the matching equation.

a. There were 4 bugs in the garden, and then 9 more bugs came. How many bugs in all?
13 – 4 = 9
10 + 3 = 13
4 + 4 = 8
4 + 9 = 13
Answer:
Initially Number of bugs in the garden = 14
Again number of more bugs = 9
Then overall bugs in the Garden : 14 + 9 = 13

b. Fourteen frogs were in the pond. Then 6 fogs hopped away. How many frogs were left?
14 + 6 = 20
14 – 6 = 8
14 – 4 = 10
12 – 6 = 6
Answer:
Number of frogs in the pond = 14
Number of frogs hopped away = 6
Number of Number of frogs left : 14 – 6 = 8

c. There were 12 penguins standing on the ice and 2 penguins in the water. How many more penguins were there on the ice than in the water?
12 + 2 = 14
2 + 8 = 10
12 – 2 = 10
14 – 12 = 2
Answer:
Number of penguins standing on the ice = 12
Number of penguins in the water = 2
Number of penguins there on the ice than in the water : 12 – 2 = 10
