Tutoring and Executive Functioning | The Foundation.

Geometry is often a student’s first encounter with the formal logic of “proofs.” This is just as important for the future of mathematical logic as algebra is for the future of computational ability! Accordingly, our Geometry tutors don’t skimp. At Strength in Numbers, we teach the basics and teach ’em right:

• Coordinate geometry
• Proofs
• Constructions
• Many other topics 🙂

Of course, there isn’t just one way to think in math. The fact that Geometry is often a student’s first math class that engages critical reasoning faculties means there is an opportunity to exercise decision-making in a way that prior classes haven’t really developed. That’s one reason our Geometry tutors apply a consistent focus on multiple possible approaches.

By focusing on spatial reasoning and the “Statement-Reason” logic of proofs, we help to turn a potentially confusing year into a masterclass in critical thinking. When you work with us on your class, you’ll come out a more rigorous, careful, and logical thinker.

Buckle your seatbelts, because things are about to get non-real. Algebra 2 is when you first encounter many, many difficult topics, but never fear! Our Algebra tutors can help with even the hardest problems:

• Complex numbers
• Logarithms
• Radical equations

Algebra 1 poured a foundation for the “house” of mathematics; now Algebra 2 starts to “frame” that same house. Our entire staff understands the importance of developing these foundational skills, and can take you from hesitance to confidence.

Our academic experts are carefully vetted to ensure the very highest level of skill not just in understanding this tough subject, but also teaching it to newcomers. We don’t just show you how to solve the topic at hand; it’s all about expansive thinking and problem-solving. One of our favorite questions is “what about this related problem?” – the idea being to build not an archipelago of disconnected mathematical ideas, but a densely connected conceptual framework that can support a lifetime of future learning.

Enjoying and excelling at this tough subject is possible, we promise. For Algebra tutoring, there is no better solution than Strength in Numbers!

True to its name, Precalculus is the final class before the calculus sequence. It’s Algebra 2 on steroids! The goal of this class is to cement the skill set that will be required in calculus. Our Precalculus tutors make sure that by the time you take the next step of abstraction in calculus, foundational skills have become second nature. No matter what you’re working on, we can help:

• Trig identities
• Unit circle fluency
• Exponential growth and decay

The goal of Precalc tutoring is twofold: we want to instill deep conceptual confidence, but also to ensure students have strong computational and problem-solving skills. Work with our Precalc tutors on these fundamentals so that they’ve become mentally “automated” by the time you get to Calculus. That way, you can focus entirely on the new logic of Calc when you get there.

Paging Dr. Newton. Calculus is one of the greatest achievements of the human mind. Really, it’s fundamentally simple: whereas Algebra deals with the value of a quantity, Calculus deals with the rate of change of a quantity. But if it were as “simple” as that, Calculus wouldn’t be so legendary for its difficulty – and Calculus tutoring wouldn’t be so popular! We work with the entire curriculum, including AP Calculus AB and AP Calculus BC, as well as Honors Calculus and Multivariable!

• Derivatives
• Related Rates and Optimization
• Integrals
• Curve Length
• Slope Fields and Separable Differential Equations

There’s no way around it: Calc is tough. But it’s not impossible, especially if you are working with the right Calculus tutor! If you’ve really put in the legwork in prior classes, you will be well-positioned to succeed. Our Calc tutors understand the types of reasoning and techniques that unlock this difficult subject.

Statistics is the science of making decisions based on incomplete information. The computational component of the subject is really difficult, so it typically uses computers and calculators very heavily. Our Statistics tutors know how to guide you through the human element: the interpretation of those results. We know how to navigate this conceptually challenging topic, even the tough concepts. Yes, we do AP Stats and College-level Statistics!

• Conditional Probability
• Normal Distribution and t-Distribution
• Hypothesis Testing

For a lot of students, Statistics is a breath of fresh air, because it means a break from tedious calculations and algebraic manipulations. But it does also involve a mindset shift: going from “computing” to “interpreting” involves a major reset. Stats tutoring with us can help! We have been helping people succeed in Stats for many years, and would be glad to help you too.

Our expertise extends into the University “Core” for STEM majors. Our advanced math tutoring staff can provide high-level support for many higher-level classes:

• Differential Equations Tutoring
• Linear Algebra Tutoring
• Real Analysis Tutoring
• Topology Tutoring

Math doesn’t stop after high school – in fact, if you’re continuing through college, it only gets harder. But for math, hard means awesome! If you’re taking one of these high-level classes and looking for Differential Equations Tutoring, Linear Algebra Tutoring, Real Analysis Tutoring, or Topology Tutoring, please get in touch with us. We’d love to help!

Chemistry is sometimes taken before physics, sometimes after. If it’s taken before physics, students can sometimes struggle with the algebraic nature of the subject, and especially the dimensional analysis and unit conversion (sometimes called “fenceposting”) required. Our Chemistry tutors are awesome at helping you understand every part of this difficult science subject:

• Stoichiometry: Balancing, Reaction Yields
• Atomic structure: Molecular shapes and VSEPR
• Bonding: Electronegativity, Ionic/Covalent bonding
• Periodic trends: Atomic radius, Transition metals

Chemistry and physics form the Algebra 1 and 2 of understanding science; in order to really comprehend the world, you need to master the basics of these fundamental subjects. Our Needham and Wellesley Chemistry experts are master of the subject; we even have some university professors on staff to handle even the thorniest Chem class. Yes, we cover AP Chemistry!

We can help with even the most difficult chemical concepts, such as equilibrium and thermodynamics. No matter what your Chem class has in store for you, our awesome Chem tutors in Needham and Wellesley can be your secret weapon!

Physics is, essentially, the study of forces and how they cause or impede motion. But of course, the devil is in the details, and man, the details are tough. But not to fear – our Physics tutors in Needham and Wellesley are here to help! We help with the entire curriculum:

• Momentum: Conservation, Impulse, Collisions
• Kinematics: 1- and 2-dimensional
• Thermodynamics: Heat transfer, Phase change
• Newton’s Laws: Forces, Inertia, Free Body Diagrams
• Electromagnetism and Circuits: Kirchhoff’s Laws, Coulomb’s Law

We know these and many other topics inside and out. Yes, we cover AP Physics 1 and 2, as well as AP Physics C Dynamics and AP Physics C Electromagnetism. We can even teach you Physics over the summer as a preparation for the class in the fall – something many of our students have done and ended up getting easy A’s in the school year. To excel at Physics in Needham or Wellesley, go with the best at Strength in Numbers!

Writing is a structural discipline. Our English Writing tutors deconstruct the “essay” into a repeatable, logical process, focusing on thesis development, the “Claim-Evidence-Warrant” framework, and rhetorical strategy, without ever losing the focus on your own form of expression.

• Expository writing: learn how to write concise, compelling, informationally dense descriptive materials. 
• Rhetorical writing: learn how to write in a convincing, persuasive manner.
• Personal essays: perfect the craft of putting your ideas in your own voice.

From creative narrative to technical research papers, our awesome English Writing experts help students find their voice while mastering the formal syntax and organization required for university-level composition. If you’re looking for focused help with admissions essays, we offer that as well, as a devoted service!

Success in History depends on “Historical Thinking Skills” rather than rote memorization. Thankfully, our staff includes highly experienced History teachers capable of providing expert guidance across the entire AP spectrum. Yes, we tutor AP European History, AP US History (APUSH), and AP World History! We specialize in the “Document-Based Question” (DBQ) and the Long Essay Prompt, teaching students how to synthesize primary sources into cohesive, evidence-backed historical arguments.

Don’t get confused by the blizzard of names and dates. Our History experts can help you to see through the thicket and get to the heart of matters historical. Understand the significance of many world events throughout history:

• Chinese Dynasties
• French Revolution
• American Revolution
• Tons and tons more! (Turns out more history is always being generated, and the world’s been around for a long time!)

Of course, nothing matters if your teacher is just droning on and on at you about the subject. We make sure that our History teachers are enthusiastic presenters of material – there’s nothing better than learning the subject from someone who makes it fun! Work with a History tutor at Strength in Numbers and watch your grades skyrocket!

German is a language of precision. We help students navigate the “Case System” (Nominative, Accusative, Dative, and Genitive) and the rigid rules of word order that often frustrate learners. By focusing on the structural mechanics of the language, we help students build a “vocabulary architecture” that allows them to construct complex thoughts with technical accuracy.

One thing that can be refreshing to learn is that German is actually quite similar to English in ways that make it “easier” than Spanish or French in certain ways! Our German tutors make sure to build on these similarities, so that you can turn your linguistic knowledge not just into a bunch of memorized facts, but a dense network of interconnected ideas. You know, like humans do. 🙂

Latin is the “Math of the Humanities.” It is a highly structured system that rewards precision and pattern recognition. We specialize in the logic of the declension system and the complexity of Latin syntax. This rigorous approach not only ensures success in the Latin language itself, but also provides a profound, measurable boost to a student’s English vocabulary and logical reasoning skills.

One immense benefit of learning Latin is the ability to read some ancient works in their original languages. Imagine reading Virgil in the original? Study Latin with us and you’ll be able to! In hoc classe vinces!

Success in Economics requires a unique ability to think in “Models.” We help students navigate the graphical and mathematical nuances of Supply and Demand, Elasticity, and Market Structures.

Whether it’s the game theory of Oligopolies in Microeconomics or the Aggregate Demand/Supply shifts in Macroeconomics, we provide the technical support needed to master the high-level quantitative analysis required for AP exams and university-level prerequisites. Yes, we teach AP Microeconomics and AP Macroeconomics!

Work with our awesome Econ tutors and watch your understanding of this complex topic blossom!

For many students, the hardest part of any assignment is getting started in the first place! We provide practical tools to overcome task avoidance and “choice paralysis.” Through techniques like environment design (do you really want that buzzing phone next to you while you’re trying to read Steinbeck?), we help students build the cognitive endurance required to initiate and sustain deep focus on demanding academic work.

Oh no! The exploding backpack of undifferentiated papers!

A disorganized backpack is a disorganized mind. We develop systems for digital and physical file management, ensuring that “lost” assignments become a thing of the past. Beyond the binder, we teach methods for ensuring studying yields lasting results – moving students away from passive re-reading and toward a high-retention study model that actually works on exam day.
