Solving story Problems

I am learning to solve addition and subtraction at level 3

There are 21 people at a beach, and 13 more people arrive.Show how to work out how many people are at the beach altogether?
20+10=30 ,1+3=4 so 30+4=34

Two classes go on camp together. One class has 47 students and the other has 38.Show how to work out how many students go on camp?

40+30=70, take 2 away from the 7 and add it to the 8 which makes another 10 so 10+5=15 so 70+10+5=85

3.  A farmer has 63 cows.  He buys 39 more cows.
Show how to work out how many cows he has altogether.

60+30=90, 9+3=12 so 90+10+2=102
