I hope you all had a wonderful Thanksgiving. Jumping into the week, we are continuing with division. I have been having some serious issues posting on my blog because my iPAD is being difficult. I am running an update, so hopefully it will get rid of the problems!
We go through three steps when we have a division problem.
1. Estimate
2. Solve
3. Check
On number 1b, you can see that we are dividing 37 from 158. 37 is the divisor and 158 is the whole. Let's go through our steps to solve this problem!!
1. Estimate:
I am going to start by rounding 37 to 40. I then think about the multiples of 4 or 40. I do this to find a number I know 40 will go into evenly. I know that 4 goes into 16, so I am going to round 158 to 160. 160 divded by 40 equals 4. This is my starting point.
2. Solve
I will start by setting up my division problem. Does 37 go into 1? No. Does 37 go into 15? No. Does 37 go into 158? Yes, but I am unsure of how many times. However, I am going to start with 4 because that was my estimated quotient.
Now, multiply 37 x 4. This equals 148. Now I plug this number into my division problem and subtract to get a remainder of 10.
3. Check
I multiply my divisor 37, by 4 which equals 148, then I add my remainder which is 10 to get 158. This proves that our answer is correct! Yay!
When it comes to solving the story problems, it is all about re-reading the problem, and breaking it up.

Thanks see u tomorrow
