MathNet 4 Kids Project 2000/2001 
We have partnered with another third grade class to exchange monthly math challenges using email. This project allows us to meet two of our curriculum requirements; identifying and using basic computer communication systems (PA State Standard 3.7.3) and practicing mathematical problem solving and communication (PA State Standard 2.5.3). Math challenges we receive and send will be posted below. We hope you will enjoy trying them with us!
