Skip Counting and Repeated Addition

Repeating addition and skip counting are strategies for multiplication and divison.

Skip counting is counting up or counting down by a certain number using addtion.

Here's a Problem Sam has seven, 5 doller notes how much money does he have all together?. 

5, 10, 15, 20, 25, 30, 35. The answer is 35 dollars because if you skip counted in fives 7 times the answer is 35.    

Repeated Addition is repeating a the same number using addition.For example 7+7+7+7+7=35. Here's a problem Mike was at the beach for five days he collected 14 sea shells every day to keep how many shells does he have in total?  14 +14 +14 +14 +14 =70 the answer is 70 because 14 is added 5 times.                                                                    

I learnt a lot about skip counting and repeated addition.
