Get in the Kitchen! I was very hesitant for a while with my son when it came to the kitchen. I worried about the GIANT mess that would be left when he was done "helping". You don't even have to take on the entire project with them! You can start small and let your child help with measuring certain ingredients. You can modify the difficulty of the 'lesson' by talking about the different kinds of measuring cups and seeing what other measurements can also add up to equal one cup, etc.
Children can take classes from various organizations that will support their mathematical development. These organizations may offer classes in the summer or on the weekends. Some of the classes can teach children how to build robots, toy cars, toy airplanes, etc. These classes may be in the area of engineering, computer science or some other technical field.
The parent's role in their child's math development is very important and should start as young as possible. Teaching young children how to count, add and subtract numbers in their head without pencil and paper can stimulate the brain to think mathematically. Parent s can start the process by teaching children how to count from one to one hundred. Teaching children how to mentally figure out math problems should also be part of this process.
Use things around the house that they already know and love! : My son has a HUGE adoration for his Thomas Trains... he can tell you every single trains name, number and color. When we started working on recognizing numbers and colors, I tried to use posters, games, workbooks, etc that would help him learn to recognize them... all to no avail! One day, we were playing with his trains, and HE asked me what number one of the trains was. Bells went off in my head and I realized that I could cater his natural curiosity about his beloved trains, and still be 'teaching' him to recognize numbers at the same time!
