For week five some new things that I learned were how to solve money problems and how to solve time problems using a time line. When I solve these problems what I usually like to do is add up to solve money problems, for example lets say you buy 10.50 worth of groceries and you pay me with a 20.00 I take the total 10.50 and count up +.50=11.00 and then plus 5.00 equals 16.00 and plus four equals 20.00 meaning that you gave her back 9.50 in change.
For time problems it gets tricky becuase some have hours, minutes, and seconds!
How I figured out how to solve time problems I start with a timeline and then I count up the seconds first on the timeline then the minnutes and then hours to get me a total.
I am going to show you a video where they give an example of solving a time porblem enjoy :)
So during week 4 what we did was learn all the differant ways to solve addition and subtraction problems. Growing up all I knew how to do was the traditional way of solving problems, so when we were asked to solve the problems in a differant way I struggled becuase my mind was set on only solving them the traditional way. After the second problem though I started to get a hang of using other methods to solve a problem.
Below I will explain some of the differant methods I learned
Problem #1 34+28
Give and take
34+28=
30+32+62
What you do above is take 2 away and add them to 28 in order to make it into a happy solid number and the 34 then becomes a 32. Then you add both 30 and 32 to get 62.
Partial sums is the method where you break up the tens colomn and the one colomn and you add the tens first, so 3 would be 30 and 4 would be 40 to give you 50. Then you add the ones which are 8 and 2 which give you 12. Finally you add the 50 and 12 to get 62 your final answer.
Finally above is a video explaining the partial differances method which is used to solve three digit problems. This is one of the other methods that I learned during class to solve subtraction problems. Hope you enjoy the video!
