We just finished learning about counting money and now we will start Unit 6 which focuses on learning how to add double digit equations in our heads.
We will learn how to add 10 to double digits...for example 51+10= or 51+30= The kids will learn to count on and add the tens. 51+10= 51 add 1 ten would be 61! 51+30= 51 add 3 tens would be 61, 71, 81!
We will also learn how to add tens and ones to a double digit number. 51+15= 51 add 1 ten would be 61 and then add 5 ones would be 62, 63, 64, 65, 66! Or 51+35= 51 add 3 tens would be 61, 71, 81. Then add 5 ones. 82, 83, 84, 85, 86!
I know this may look confusing. Hard to describe this wonderful strategy on a website! Make sure you look at how your kids did their lessons and try to teach it the same way on their homework!
