EOI Exams

EOI (End of Instruction) Exams:

Algebra 1: May 3 & 4
Algebra 2: May 10 & 14

Booklets with information for parents and students will be sent home next week - this include practice questions and testing suggestions.

As soon as we finish the current chapters in our classes, we will be doing EOI review until testing is complete - this will consist of doing EOI-type problems, discussing testing techniques, and summarizing the topics we've covered.

REMEMBER: for this year's Freshmen & Sophomores, they MUST pass the Algebra 1 EOI to graduate high school in the state of Oklahoma. I am taking this very seriously and I hope you are too.
