Abdallah Abusharekh

I'm Abdallah from Gaza, 52 years old. I have teached maths for 23 years. Teaching math and discovering math are the most intersting for me, but in the last 7 years I became intersed in thinking of best methods to introduce new abstract concepts for young children. I have designed a small material that can be used as good introduction to abstract math for kids of k-3 and k-4. They can finally susbtitute to find the numerical value of 2x + 3y for given x,y. I also discovered a gap in triangle congrouncy axioms that will be published as an article. Also I'm intersting in reading the questions and the answers in this site.
