Here I submitted my recitation slides and "record Changes" sheet. For the recitation slides, I do incorporate some information from shared resources, but I found the first several slides I made helped student to understand population vs individual changes, and to understand the 'modeling process'.

The "record changes" sheet was very useful, helping students writing down mutations, and find mutations based on genes (related to Q11 ). Usage of this sheet could possibly circumvent building beads, but the beads help visualization and make students experience the "mutation process".
