On this page you will find differentiation strategies.  The first section is learning about the different strategies and how to use them.  The second has premade  differentiated lessons, units, and ideas.  These you should read carefully because then have been premade and may not meet your standards.  You can feel free to make a copy and modify them if you choose.
