McGraw-Hill My Math Kindergarten Answer Key Chapter 5 Lesson 3 Use the + Symbol
Explore and Explain
3+4 is 7
Number of dogs in first group is 3
Number of dogs in second group is 4
Therefore, total number of dogs is given by 3 + 4 is 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.
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.
Teacher Directions: Count the dogs in the first group. Write the number. Trace the plus sign. Count the dogs in the second group. Write the number. Use 
to model each group. Join the two groups. Write how many dogs there are in all.
