8th Grade Math

Hello!

We live in New York state and will be homeschooling our 8th-grade daughter this year. I was wondering if anyone could explain or point to an explanation of the differences in the 8th-grade math curriculums at Khan Academy. There's 8th-grade math, 8th-grade (Eureka/Engage NY), and 8th-grade illustrative. Is there a quick summary of the differences between these?

Thanks!
