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! |

It seems that the elf has lost some numbers and needs to find them. He says they are special numbers because they have three things in common. 1. They are all between 300 and 600. 2. The middle digit in each number is odd, and the other digits are even. 3. The sum of the digits in each number is 13. What numbers did the elf lose? |
