Question 1.
plus sign
+
=
Answer: +
The + in general called as addition symbol. This addition symbol is usually used to indicate that two or more numbers should be added together.
Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the result or the final answer we get after the process is called the sum.
Question 2.
equals sign
+
=
Answer: =
The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation.
Question 3.
in all
Answer: 2 + 3 = 5
Number of ducks in the first group = 2
Number of ducks in the second group = 3
Therefore, total number of ducks = 2 + 3 = 5
The + in general called as addition symbol. This addition symbol is usually used to indicate that two or more numbers should be added together.
The = equals symbol is used to show that the values on either side of it are the same. It is most commonly used to show the result of a calculation.
Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the result or the final answer we get after the process is called the sum.
Directions: 1. Circle the plus sign. 2. Circle the equals sign. 3. Count the ducks in each group. Write the numbers and trace the symbols. Write how many ducks there are in all.

Question 5.
Answer: 6 + 1 = 7
Number of bees in the first group = 6
Number of bees in the second group = 1
Therefore, total number of bees = 6 + 1= 7
The + in general called as addition symbol. This addition symbol is usually used to indicate that two or more numbers should be added together.

Question 6.
Answer: 3 + 7 = 10
Number of butterflies in the first group = 3
Number of butterflies in the second group = 7
Therefore, total number of butterflies = 3 + 7 = 10
The + in general called as addition symbol. This addition symbol is usually used to indicate that two or more numbers should be added together.

Question 7.
Answer: 2 + 4 = 6
There are two horses to ride.
The number of horses in another group = four
Total number of horses = 2 + 4 = 6

Directions: 7. There are two horses to ride. Draw four more horses to show another group. Write the numbers and trace the symbols.
Reflect
Directions: Count the cupcakes and write the number, Draw more to make 10. Write the number. Trace the symbols.
Answer: 5 + 5 = 10
Number of cupcakes before added = 5
Number of cupcakes to be added = 5
Therefore, total number of cupcakes = 5 + 5 = 10
