Math Homework for Tonight
I've made a few notes for some of the students in their books that they need to fix. Here is the homework page. They need to do 3-6 and use our estimation strategies, not just add it.
Addition & Estimation
Alright, I've had a change to look over our Addition Math pretests! Most of you did amazing! Some of you already know a lot of the concepts we will be covering this year! Yay!! However, there were a couple places we struggled.
Did you know that the words sum, add, addition, plus are all SYNONYMS!! This means they all mean the same thing! We want to find the SUM of two or more numbers, we find it by doing ADDITION!
Here is a few more that you can look for in your word problems/story problems:
Estimation was somewhere many of us struggled with, so that is what we will be learning about today.
When we estimate a number, we are making a guess at what the number will be close to by using clues that are provided.
For example: If I want to estimate about how many beads I have to make a necklace. I have 34 BLUE beads, 79 PURPLE beads, 29 GREEN beads, and 56 ORANGE beads, I can round these numbers to make it easier for me to add in my head:
Around:
30 Blue beads
80 Purple beads
30 Green beads
60 Orange beads
I can now add in my head: 30+80+30+60 is around 200 beads!
What about for the larger numbers we have been using?
Mr. Dan had 1445 books and Mrs. Taylor had 791 books. Estimate how many books the grade 3 teachers had altogether.
We can estimate to the nearest 1000, nearest 500, and nearest 100.
Nearest 1000:
Mr. Dan has about 1000 books and Mrs. Taylor has about 1000 books, so they have around 2000 books altogether.
Nearest 500:
Mr. Dan has about 1500 books and Mrs. Taylor has about 1000 books, so they have around 2500 books altogether
Nearest 100:
Mr. Dan has about 1400 books and Mrs. Taylor has about 800 books, so they have around 2400 books altogether.
Which estimation is the closest or most accurate?
