Lesson- 1: Addition Facts.


           Learning objective: Students will be able to understand the properties of addition.


              When we put things together, we do addition. ‘+’ is the sign of addition.


              Numbers those are added are called addends.


              The result that we get is called the Sum or Total.




               Example: -
               T       O


               2        2                  Addend


           +    1         2                  Addend



               3         4                 Sum or Total



              Addition Facts



              Fact 1 – Any number added to ‘0’ gives the number itself. Example: 3+0=3


              Fact 2 – Any number added to 1 will give the next number. Example: 3+1=4



              Fact 3 – Even if the addends are interchanged, the Sum remains the same.


               Example: 4+3 = 7



                             3+4 = 7
