I don't know of a resource that gives that many inference questions but these may help:
I like to use poetry to introduce and practice inferences. I often use Reflections on a Gift of a Watermelon Pickle (http://www.amazon.com/Reflections-Wa.../dp/0688412319
) I will read them a poem without telling them the title and they have to guess what it is about. Some good poems: Toaster and Apartment. For your purpose, you could type them up without the title and then have students explain what it is.
Here is a website that teaches about inferences: http://www.manatee.k12.fl.us/sites/e...ola/rcinf1.htm
Inference cards from that same website (8 cards total):
Inference examples (you could use one a day for 4 days):
Comprehension Mini-lessons (book to buy):
I have this book and I would say that it has 3 or so pages of inference examples with probably 4 examples on a page. It does teach a good strategy for this skill.
Reading Passages that Build Comprehension: Inference (book to buy);
This is for grades 2-3 but you can view some sample pages to see if it is too easy.
There is also a book for Grades 4-8 but there is no information about it: http://shop.scholastic.com/webapp/wc...-1_10001_10002
Guided Reading Inference Lesson:
Strategy Cluster 4 from Comprehension Toolkit is about making Inferences: http://www.comprehensiontoolkit.com/annotated.asp
These lessons are VERY good but they take awhile (about an hour for each lesson). I think they are really best with the other strategy clusters. They aren't a worksheet but it will help build better readers!
