This unit can be used for differentiation and GT enrichment. It includes an activity menu with 25 different options. There are five each for Reading, ELA, Math, Science, and Social Studies. They are based around the Science Unit of Investigating the Natural World. The activities can be used to last between 1 week through 5 weeks, depending on your curriculum schedule.
Most activities can be conducted with basic classroom supplies. Templates are included for Science investigations and book studies. There are also rigorous math problem sheets based on 3rd grade Math TEKS.
This pack also includes the full Recycling Lab Investigation which is otherwise available separately on my page.
