We are trucking right along and have completed our study of place value for the time being. Next week we will move on to Mental Addition and Subtraction Strategies as well as estimation.
On Monday we will introduce the Chapter will some number bond review from second grade as well as a review of rounding to the nearest ten. For example: 4 and 5 make 9, so 4+5=9 and 5+4=9, as well as 9-4=5 and 9-5=4.
On Tuesday we will go over two Mental Addition strategies without regrouping. The first one is called, "Add the tens, then the one"
EX: 45+62 is like 45+60. This equals 105+2=107
The second strategy is called, "Add the tens, then subtract the extra ones."
EX: 35+58 is like 35+60. This equal 95-2=93
On Wednesday we will work on Mental Subtraction strategies very similar to Tuesday, only now we will be subtracting. In one strategy, you are rounding down and adding extra ones. In the second strategy, you are rounding up, and then subtracting the extra ones you tacked on when you initially rounded.
Ex #1 68-34 is like 68-30. This equals 38-4=34.
EX#2 63-48 is like 63-50. This equals 13+2=15.
On Thursday the kids will be adding larger numbers close to 100 mentally.
Ex#1 86+95 is like 86+100. This equals 186-5=181.
Ex#2 94+97 is close to 100+100. This equals 200-6, 194-3=191.
The kids will be playing some fun station games to practice these skills.
On Friday will be FAST FACT FRIDAY!! This Friday's grade will be entered into the grade book.
In Science we will be moving on from learning HOW to make observations, to actually making some observations through the Scientific Method and an experiment we will conduct with the kids early in the week!
Next week we will have a counselor lesson with Ms. Clifton on Monday, Picture day on Tuesday, and Curriculum night on Thursday at 5:30. Please watch this video in internet explorer before you come to curriculum night so you can be ready with great questions!
See you Thursday!
