Mathematics lessons to children of all ages

I have BEng in Electrical and Electronics Engineering and have been practicing engineering in the oil and gas industry for close to 9 years where i calculated most of my variables for proper application.
I also teach children in my church back in Nigeria. Therefore, i understand children's and their learning span and how to transfer knowledge withing shortest periof of time. I believe this skills will help me to ensure that mathematics is a subject to admire and love inits simplicity. Looking forward to having a great time.
