I used this unit with the book Fantastic Elastic Brain by Dr. JoAnn Deak. It took approximately 3 days to work through everything. The powerpoint and worksheets can be used without the book you would just need to go over the parts of the brain that is covered. Although, I also found a digital copy of it on youtube.
I teach a self contained special education class and this took us approximately 3 days. The students were engaged and enjoyed learning about the brain and that there were so many hands on activities. Ever since I taught my growth mindset unit and this elastic brain unit I have noticed my students working harder, they are encouraging each other to have a growth mindset and to keep trying.
Additional Materials - Playdoh, very small rubber bands, crayons or colored pencils. (these were all things I had in my classroom)
If you have any questions please let me know I am here to help and love helping other educators as well!
