Have you heard of Universal Design for Learning (UDL)? This is a framework based around including accommodations and modifications in your lesson planning, rather than introducing them to your plan after the lesson has been created! I've found this style of lesson plan creation allows you to reach all students, without you doing much "extra" work to give students other activities or different worksheets! Accommodations can help all students, not just those who have special needs.
There are tons of videos on YouTube showing UDL in action. Hope this helps!
