Children are actually very good at teaching us what they need in order to help them learn. Tune into your our children, observe what interests them, and factoring their cues into learning experiences that will be fun and engaging for you and them.
The biggest lesson we have learned from children is how important technology is to them. Even something as simple as using a calculator function on a basic model cell phone to teach number recognition is so much more enticing than the traditional means of learning.
Ask not what your child can learn from you, but what you can learn from your child!
