Please share your resources for learning and teaching fractions...sites, videos, worksheets etc.

I am looking for online resource similar to this: https://worksheetgenius.com/math/fractions-add/ with fraction focused worksheets but with pizza or pie pictures. Something easy and engaging.

    $\begingroup$ Could you give some context here, like is this for self-learning, at school, supplemental learning, adult education? Age of the target audience? Language preferences? Online or physical stuff? $\endgroup$

Update for Edit: In the updated question, the OP asks for "pizza or pie pictures." Personally (as based on research) I would advocate against circular models for introducing fraction equivalence or adding and subtracting fractions. Rather, I would recommend a rectangular model (e.g., brownie pan) because it adapts more readily to the multiplicative context. I don't mean that one should dedicate themselves to avoiding circular representations (pizzas are realistic representations, and pies are especially common in infographics) but I think it's important to think – for fractions and more generally – about the models we introduce and how well they will adapt to the next topic(s) of study.

I used materials through the Elementary Math Project but I do not see a place in which they can be freely and publicly accessed. Among written resources, I recommend the NCTM book:

Clarke, Carne, et al. Developing Essential Understanding of Rational Numbers for Teaching Mathematics in Grades 3-5. Essential Understandings. National Council of Teachers of Mathematics. 1906 Association Drive, Reston, VA 20191-1502, 2010. Link.

It is possible to purchase this in printed book form or in digital PDF form. As a consequence (in part) it is also possible to find a pirated copy of the text online; I think it is worth adding to one's own library.

    $\begingroup$ I have not voted up or down, but perhaps you are receiving downvotes for your recommendation of piracy. $\endgroup$

    $\begingroup$ @shoover Hm. That's possible. To be clear, I am indicating that pirated versions exist, but I think it's worth buying! (As possible.) $\endgroup$ Commented May 2 at 3:35

For helping k12 teachers understand fractions better, and also get a grasp on why that's important, I think Liping Ma's book, Knowing and Teaching Elementary Mathematics is an excellent resource.

Another book for teachers that I'd recommend is Marilyn Burns', Teaching Arithmetic: Lessons for Introducing Fractions, Grades 4-5. (She has lots of useful books on teaching math.)

For students, I love the Beast Academy curriculum. [Disclaimer: I currently work part-time for their parent company.] Here's a printable they've provided, so you can get a sense of their style.

When asking adult students to review fractions, I often turned to Key to Fractions, a set of 4 booklets.

All of these can probably be found used online quite inexpensively.
