OAA 8th grade math - how many practice tests before the actual assessment?
My daughter is taking the Ohio Achievement Assessment in math next month and I'm trying to figure out the right amount of prep without burning her out. She's been getting around 72-75% on the practice tests we've been doing at home, and from what I've read the proficiency cutoff for 8th grade math is around 80%. There's a real gap to close in about 4 weeks.
We've been doing about 30-45 minutes of practice on school nights, which she tolerates but definitely complains about by day 3 of the week. The number patterns and functions section is where she loses the most points. She's solid on basic algebra and geometry but the extended response questions where she has to show all work and explain her reasoning are costing her a lot of points.
My older son took the OAA three years ago and did fine, but I remember reading comprehension being his bigger concern at the time. Different kid, different subject, so I'm not sure how comparable the prep approach is. Anyone been through the 8th grade math specifically in the last year or two?
We did about 8 full practice tests over 6 weeks before the assessment. I think 6 would have been enough honestly. By the 7th one my kid was fatigued and scores started to plateau rather than improve.
Number patterns and functions is a common weak spot for 8th graders. Khan Academy has a solid unit on it that's less intimidating than most workbook materials if she's getting frustrated with the textbook approach.
My son went through 8th grade math OAA last spring. He was scoring around 70% on practice tests in January and ended up at 83% on the actual assessment. The real exam felt slightly easier than some of the harder practice materials we found online.
The extended response section is worth a lot of points and kids often rush it. Coach her to write out her reasoning even when she thinks the answer is obvious - partial credit adds up and graders look for that work.
I actually failed my first attempt and had to retake it, so I'll tell you what I did differently. The big thing wasn't how many practice tests I did -- it was stopping to actually figure out why I missed each question instead of just moving on. I was rushing through practice tests thinking volume was the point. It wasn't.
At 72-75% she's closer than she probably realizes, but that gap usually comes from a few specific topics, not everything. I'd do maybe two more full practice tests and spend way more time on the questions she's consistently getting wrong. That's honestly what turned it around for me the second time. Quality over quantity, at least at this stage.
