It says ratios. It's fractions, from last year.
Grade 9 math trouble often starts years earlier. We find it, teach it, and tell you what we found, in writing, every week.
Canadian 15-year-olds scored 485 in math on PISA 2025, down from 497 in 2022.
The EQAO Grade 9 math assessment counts for 10% to 30% of the final course mark, set by each school board.
If math suddenly got hard this year, it usually didn't start this year.
Grade 9 uses everything from Grades 5 to 8 at once: fractions, integers, ratios, the equal sign. A gap that was easy to work around in Grade 6 shows up as a wrong answer in a Grade 9 ratio question. Extra practice on this year's topic often doesn't help, because the gap is older. Finding it does.
How we teach
The second class uses your child's own work
The teacher reviews what students handed in, picks real pieces of work, and the class works through where the thinking went. Built on the Five Practices for mathematics discussion (Smith and Stein).
See it before the rule
Fractions are taught with fraction strips, so students can see why one half plus one third isn't two fifths before any rule is given.
Practice that makes them think
Each practice set changes one thing at a time, so students have to notice what changed instead of repeating a step.
These are design choices drawn from published research on teaching mathematics, not results. The first cohort is how we find out how well they work here.
Example report (an illustration, not a real child)
A Grade 6 student • Adding and subtracting fractions • six items, about ten minutes
Adds the tops and the bottoms
Your child adds fractions the way they add whole numbers — top plus top, bottom plus bottom. One half plus one third becomes two fifths. The answer is smaller than the half they started with, which is the giveaway, and it is worth asking them whether that can be right before telling them anything.
What we saw: adding one half and one third on strips, they shaded 2 of 6 — the two top numbers, ignoring the sizes.
Reports show causes, not scores. We never compare your child to anyone.
Why parents choose ChronosLearn
Certified Ontario teachers
We only hire Ontario College of Teachers members with a math qualification and a current Vulnerable Sector Check.
Ten students, maximum
Two live 45-minute classes a week. The second one works through what your child actually got stuck on.
It in writing, every week
What we found, the evidence, and one thing to ask your child. No scores. No comparisons.
Starts where the trouble is
The first four weeks rebuild the Grade 5–8 skills Grade 9 assumes. Then MTH1W, taught to a set plan.
Ask any math program these four questions
- Is every teacher OCT-certified, with a Vulnerable Sector Check?
- How many students are in the class?
- Will you tell me in writing what's actually wrong?
- Is it the Ontario MTH1W course, taught to a plan?
