Basic strategies and first problem

I like the R.U.M.O.R strategies.

1. R. – Read
2. U. – Underline Question
3. M. – Mark Information
4. O. – Operation
   • Write Equation
   • Build a model
   • Draw a picture
   • Make a list
   • Find a pattern
   • Work backwards
   • Guess and check
   • Others
5. R. – Recheck for Reasonableness

Now, Let’s look at the first math problem

About this blog

I am a father of two kids and interested in solving math problems. However, I am not smart enough to be a mathematician. My son is in grade 9 and what surprised me is his skill in solving math problems. Most of the time he has no idea how to start unless it is very straightforward. I remembered he does not have homework until grade 7. What I understand is that you need to practice if you want to be good at it. I started to give him math problems and teach him the skills to solve all types of math problem. I collected lots math practice problems and am willing to share them to help the kids on their mathematics. I am planning to post one problem every day or every two days and will give detail solutions. I hope you will like it and any support will be appreciated.
