Answer:

Explanation:
There are total five cubes in the train shown. In those some are colored gray. We need to separate total cube train into two parts to know how many cubes are gray. Substract the number of non-gray colored cubes from the total number of cubes to get the number of gray colored cubes. So, if we substract three from total five cubes, then the total number of gray colored cubes are two.

• Spiral Review
  Question 2.
  
  Answer:
  
  Explanation:
• In the first frame, we can see that there are total ten number of counters and five are not colored grey. If we substract the number of non-colored counters from total number of counters, then we will get the total number of grey colored counters. So, substracting five from the total ten counters gives us five grey colored counters.
• Similar to the first frame, if we see in the second frame, there are total ten number of counters and four are not colored grey. If we substract the number of non-colored counters from total number of counters, then we will get the total number of grey colored counters. So, substracting four from the total ten counters gives us six grey colored counters.
• For the third frame, the same logic will apply here as well an substracting three from ten gives us seven grey colored counters.
• For the fourth frame, substracting two from the total ten counters will give us eight grey colored counters.
• For the fifth frame, substracting one from the total ten counters will give us nine grey colored counters.

Question 3.
THINK SMARTER+

Answer:

Explanation:
In the above image, we can see a four cube train. In that, one is red cube and three are blue cubes. We have to choose the correct answer for number of red cubes by subtracting the number of blue cubes from total number of cubes. If the answer matches with the number of red cubes, then the answer is ‘Yes’ or else ‘No’.

• In the first number sentence, subtracting two blue cubes from the total four cubes will not give the correct number of red cubes. The answer doesn’t match with the number of red cubes and so the answer is ‘No’.
• In the second number sentence, substracting three blue cubes from the total four cubes equals to one red cube. So, the answer is ‘Yes’.
• In the third number sentence, substracting one blue cube from three cubes will not give correct number of red cubes. So the answer is ‘No’.

Question 3.

Answer:

Explanation:

• In the first frame, we can see that there are total ten number of counters and nine are not colored grey. If we substract the number of non-colored counters from total number of counters, then we will get the total number of grey colored counters. So, substracting nine from the total ten counters gives us one grey colored counters.
• Similar to the first frame, if we see in the second frame, there are total ten number of counters and eight are not colored grey. If we substract the number of non-colored counters from total number of counters, then we will get the total number of grey colored counters. So, substracting eight from the total ten counters gives us two grey colored counters.
• For the third frame, the same logic will apply here as well an substracting seven from ten gives us three grey colored counters.
• For the fourth frame, substracting four from the total ten counters will give us four grey colored counters.
• For the fifth frame, substracting five from the total ten counters will give us five grey colored counters.

Share and Show

DIRECTIONS Tell addition and subtraction word problems. Use cubes to add and to subtract. 1. Trace the number sentences. 2. Complete the number sentences.
Question 1.

Answer:
The first cube train contains five red cubes and two blue cubes. ADD five red cubes with two blue cubes .The total number of cubes are seven.
Total number of cubes in the second cube train are seven. Subtract two blue cubes from total number of cubes are seven. Total number of red cubes are five.
Explanation:
In the first image we can see five red cubes and two blue cubes. We have to find total number of cubes. In order to get the total number of cubes we have to perform addition operation. An addition sentence is a mathematical expression that shows two or more values added together and their sum. ADD five red cubes with two blue cubes then we get total number of cubes. So the total number of cubes are seven.
In the second image we can see the total number of cubes are seven. In that two blue cubes are taken away .We have to find how many red cubes are left over there.  Number of cubes taken away are two and the total number of cubes are seven. So we have to subtract total number of  blue cubes taken away from total number of cubes . Subtract two blue cubes from seven cubes.  So we got the left over red cubes. The left over red cubes are five.

Question 2.

Answer:

Explanation:
In the first image we can see six red cubes and four blue cubes. We have to find total number of cubes. In order to get the total number of cubes we have to perform addition operation. An addition sentence is a mathematical expression that shows two or more values added together and their sum. ADD six red cubes with four blue cubes then we got total number of cubes. So the total number of cubes are ten.
In the second image we can see the total number of cubes are ten. In that four blue cubes are taken away .We have to find how many red cubes are left over there.  Number of cubes taken away are four and the total number of cubes are ten. So we have to subtract total number of  blue cubes taken away from total number of cubes . Subtract four blue cubes from ten cubes.  So we got the left over red cubes. The left over red cubes are six.

DIRECTIONS 3–4. Tell addition and subtraction word problems. Use cubes to add and subtract. Complete the number sentences.
Question 3.

Answer:

Explanation:
In the first image we can see six red cubes and two blue cubes. We have to find total number of cubes. In order to get the total number of cubes we have to perform addition operation. An addition sentence is a mathematical expression that shows two or more values added together and their sum. ADD six red cubes with two blue cubes then we get total number of cubes. So the total number of cubes are eight.
In the second image we can see the total number of cubes are eight. In that two blue cubes are taken away .We have to find how many red cubes are left over there.  Number of cubes taken away are two and the total number of cubes are eight. So we have to subtract total number of  blue cubes taken away from total number of cubes . Subtract two blue cubes from eight cubes.  So we got the left over red cubes. The left over red cubes are six.

Question 4.

Answer:

Explanation:
In the first image we can see eight red cubes and one blue cube. We have to find total number of cubes. In order to get the total number of cubes we have to perform addition operation. An addition sentence is a mathematical expression that shows two or more values added together and their sum. ADD eight red cubes with one blue cube then we get total number of cubes. So the total number of cubes are nine.
In the second image we can see the total number of cubes are nine . In that one blue cube is taken away .We have to find how many red cubes are left over there.  Number of cubes taken away are one and total number of cubes are nine .So we have to subtract total number of  blue cubes taken away from total number of cubes . Subtract one blue cube from nine cubes. The left over red cubes are eight .

Question 5.

Answer:

Explanation:
The process of taking one number or amount away from another number is called as subtraction. The result of a subtraction is called a difference. Subtraction is signified by the minus sign. For example, there are nine birds on a tree. If three birds flew away, then the number of birds left on the tree will be calculated by substracting the number of birds flew away from the total number of birds on the tree. If we substract three from six, then we get the answer as three.

Subtraction Review/Test

DIRECTIONS 1. Write how many owls are flying away. Write how many owls are left. 2. Which answers show how many counters are red? Choose Yes or No. 3. Model a five-cube train. Two cubes are yellow and the rest are blue. Take apart the cube train to show how many are blue. Draw the cube trains. Trace and write to complete the subtraction sentence.
Question 1.

Answer:

Explanation:
In the above image total number of owls on the tree are four. One owl is flying away. The number of owls left on the tree are calculated by the subtraction method. Subtract number of owls flying away from the total number of owls present on the tree which means subtract one owl from four owls. Owls left on a tree are three.

Question 2.

Answer:

Explanation:
In the above image, we can see there are total nine counters. In that, four are red counters and five are yellow counters. We have to choose the correct answer for number of red counters by subtracting the number of yellow counters from total umber of counters. If the answer matches with the number of red counters, then the answer is ‘Yes’ or else ‘No’.

• In the first number sentence, subtracting one yellow counter from the total nine counters will not give the correct number of red counters. The answer doesn’t match with the number of red counters and so the answer is ‘No’.
• In the second number sentence, substracting five yellow counters from the total nine counters equals four red counters. So, the answer is ‘Yes’.
• In the third number sentence, substracting three yellow counters from eight counters will not give correct number of red counters. So the answer is ‘No’.

Question 3.
THINK SMARTER+

Answer:

Explanation:
In the above image we can see a five-cube train. Two cubes are yellow and the rest are blue. In order to find how many cubes are blue, we have to substract the yellow cubes from total number of cubes.

• Total number of cubes are five.
• Number of Yellow color cubes are two.
• Substracting two yellow cubes from the total five cubes will give us the total number of blue cubes which are three.

Does the number sentence match the picture? Circle Yes or No. 7. Mark under all the number sentences that match the cubes.
Question 4.

Answer:

Explanation:
In the above image there are four penguins. Two penguins are taken from the set. Substract two penguins from the total four penguins and so we get left over penguins. The left over penguins are two.

Question 5.

Answer:

Explanation:
In the above image, the total number of birds are seven. In that, three birds are taken from the set. So, substract three birds which are taken away from the set from the total seven birds  and we will get the number of birds left over in the set and they are four.

Question 6.

Answer:

Explanation:
In the above picture, we can see a five cube train. In that, three are red cubes and two are blue cubes . The picture says that all the blue cubes are taken apart from the train and only the red cubes are remaining there.

• The first number sentence doesn’t match with the five cube train. Because in the above picture two blue cubes are taken away , So substracting four from five is not relevant here. So answer is ‘No’ for first number sentence.
• In the second sentence we can observe addition process takes place , which is irrelevant to the cube train as we are taking apart the blue cubes from the train actually. .So answer is ‘No’ for second number sentence also.
• In third number sentence, we can see total number of cubes are 5 and taken away blue cubes are two by substracting these we can get three red cubes . So answer is ‘Yes’ for third sentence.

Question 7.

Answer:

Explanation:
In the above image we can see a ten cube train and three number sentences. In that image we have to match the cube train with number sentence. A ten cube train contains three red cubes and seven blue cubes. Add three red cubes with seven blue cubes to get ten cube train which matches with the third number sentence. Mark for third number sentence.
