3 Ways to Find the Least Common Multiple (and How to Know Which One to Use)
Mathnasium tutors explain three ways to find the least common multiple and share quick tips on how to choose a method that fits the problem in front of us.
Your child's math progress doesn't have to stall just because their teacher or school changes mid-year. Central Florida is dealing with teacher shortages and school closures right now, and it's putting more families through a classroom change than usual.
We are Mathnasium of Windermere FL, and today we'll cover why this is happening, what actually changes in your child's math class when it does, and how to keep their progress consistent during a school or a teacher change.
Florida's schools are short on teachers, and Horizon West's schools are growing faster than the district can build for them. Both of those things raise the odds that your child gets a new teacher or a new school this fall.
As of August 2026, Florida had over 5,500 advertised teacher and staff vacancies statewide, more than at the same point last year, according to the Florida Education Association. As a result, many families may begin the school year without knowing who their child’s permanent teacher will be.
Orange County Public Schools reassigned 116 teachers in early fall 2025 after enrollment came in significantly lower than projected. Your child could start a semester with one teacher and finish it with another, with none of it being up to you.
Even when a vacancy does get filled, the person filling it may not be trained to teach math specifically. The state's own critical shortage reporting shows that out-of-field and temporary teachers have replaced more than twice as many certified teachers as they did five years ago.
Even a teacher who stays for the entire year might be brand-new to teaching math.
On March 10, 2026, the Orange County School Board voted to close six elementary schools and one middle school for the 2026-27 school year:
Bonneville Elementary
Chickasaw Elementary
Eccleston Elementary
McCoy Elementary
Meadow Woods Elementary
Orlo Vista Elementary
Union Park Middle School
The closures affected thousands of students due to a multi-year decline in district enrollment. Orange County reassigned them to neighboring schools, with impacted students and staff transitioning to their new campuses for the start of the 2026–27 school year in mid-August.
Even if your child's school wasn't one of these seven, Orange, Seminole, and Osceola County boundaries can still change after future rezoning hearings.
You can check your address against OCPS's school rezoning page to see whether a change is already on the table for your zone.
Your child's math class works differently with a new teacher or at a new school. The method, the vocabulary, the pace, and the placement can all look different than what they're used to.
Still, when their foundational skills are solid, adjusting to a new teaching style or standard can temporarily shake their confidence as they figure out what's expected of them.
The new teacher may solve the same problem in a way your child has never seen. The new approach might include:
Breaking numbers apart instead of using traditional borrowing
Using a number line to visualize math instead of standard vertical algorithms
Drawing a visual model (like a tape diagram) instead of jumping straight to an equation
Showing every step of the process instead of writing down only the final answer
Each of these leads to the same answer and the same standard.
Math vocabulary isn't universal either. One teacher may say "borrowing and carrying," while another uses "regrouping" or "decomposing units." Your child can hear the new term and think it's a brand-new concept, when it's actually the same skill under a different name.
Florida's public and charter schools follow the B.E.S.T. Standards and check progress three times a year with the computer-based FAST test. Regardless, some Orlando-area teachers spend class time on digital test-prep formats and practice questions, while others teach straight from the textbook and give paper tests.

Schools don't all teach topics in the same order or at the same pace, even within the same grade level. If your child changes schools mid-year, the old school might have covered geometry in the fall and fractions in the spring, while the new school does the reverse.
The new class might repeat a topic your child already learned, or skip one they still need.
Every school tests math skills a little differently, and schools also set their own bar for who qualifies for an accelerated track. This means your student's old school may have placed them into an accelerated track, such as 6th-grade Accelerated Math or 7th-grade Algebra 1 Honors.
That placement may have depended on:
A cutoff score on a placement test
A teacher recommendation
A prerequisite course
The new school can set different rules for that same track. If its assessment doesn't match what your student was doing before, they could end up placed a level higher or lower than you expected.

Florida's B.E.S.T. Standards for your child's grade stay the same no matter which teacher or school your child has. You can support that consistency by tracking what's already been covered and sharing it at the right time.
Here are five steps our tutors recommend to keep your child on track through the change.
Gather important classroom materials before the transition happens. Keep copies of the syllabus, course outlines, textbook titles, and chapters completed so far. Save recent graded homework, quizzes, and tests too.
Together, this shows exactly what your child has learned and how it was taught.
Share the syllabus and past assessments, and tell them the specific vocabulary your child learned, like "borrowing" instead of "regrouping." Ask how they teach and if they prefer:
Visual models
Standard algorithms
Flag what your child does well and where they struggle.
Ask both schools which B.E.S.T. Standards they've covered so far this year. If the new school skipped one the old school taught, or is about to repeat one your child already knows, you'll catch it before it turns into a confused homework night.

The new teacher's approach doesn't erase what already works. At home, let them solve problems the way they're used to, and keep a few minutes of daily practice on the basics so nothing gets rusty during the adjustment.
Most children settle into a new teacher or school within a few weeks. If the struggle continues longer for your child, especially on one specific topic, structured support tends to help most.
Structured support means working with someone who can pinpoint exactly which skill the gap is in. That's different from reviewing everything from the start. It targets the specific place your child got stuck.
Mathnasium of Windermere FL builds a personalized learning plan around that exact gap. Our tutors start with a diagnostic assessment to identify your child's current skill level, then teach from there.
