 You just go through the process of addition twice.

 First we add the digits under ones place and then add the

digits under tens place.
 For example, you wouldn't want to try and add 24 and 45

as complete numbers in your head.

 It's easier to break those numbers down into bite-sized

pieces.

 You would start by adding the numbers in the ones
column and then move to add the numbers in the tens

column.

EX-

24 + 45 = 69

Tens Ones

2 4
+ 4 5

6 9

Learning Outcome- Students are able to add two digit numbers

with two digit numbers without carry over.
