Use the Grade 10 Mathematics Reference Sheet efficiently, know which formulas it does and does not provide, and use the calculator (where allowed) as a check rather than a crutch.

What this topic is asking

The Grade 10 MCAS provides a Mathematics Reference Sheet and allows a calculator on part of the test. Using both well is a strategy skill in its own right: knowing exactly what the sheet gives, what it does not, and how to treat the calculator as a check rather than a crutch. This section is about working efficiently with the tools the test hands you.

What the reference sheet provides

The Grade 10 Mathematics Reference Sheet is available to every student throughout the test, and a copy appears at the end of the released items. It gives:

• Geometry: area of a triangle, rectangle, parallelogram, trapezoid, and circle; circumference $C = 2\pi r$; total surface area formulas.
• Volume: prism $Bh$, cylinder $\pi r^2 h$, sphere $\frac{4}{3}\pi r^3$, cone $\frac{1}{3}\pi r^2 h$, pyramid $\frac{1}{3}Bh$.
• Right triangles: the Pythagorean theorem $a^2 + b^2 = c^2$, the special right triangle ratios, and the trig ratios $\sin, \cos, \tan$.
• Algebra and finance: the quadratic formula, simple interest, and distance $=$ rate $\times$ time, with $\pi \approx 3.14$.

Because these are provided, the test does not reward memorizing them; it rewards knowing which one fits a problem and using it correctly.

What the reference sheet does not provide

Just as important is the list of essentials not on the sheet, which you must carry in memory:

• The slope formula $\frac{y_2 - y_1}{x_2 - x_1}$, and the line forms (slope-intercept $y = mx + b$, point-slope).
• The distance and midpoint formulas (the distance formula is the Pythagorean theorem applied to coordinates).
• Vertex form and the axis of symmetry $x = -\frac{b}{2a}$.
• The laws of exponents and logarithms.
• Every statistics formula (mean, IQR, correlation) and the probability rules.

A student who assumes the slope or the statistics formulas are on the sheet wastes time searching for them. Memorize the gaps.

Using the calculator wisely

A calculator is allowed only on the calculator session (the other is calculator-free). Where allowed, use it to:

• Perform arithmetic quickly and accurately, especially with decimals, large numbers, or $\pi$.
• Check an answer you found by hand, by substituting back or recomputing a different way.

But the calculator does not choose the method, set up the equation, or interpret the result. On constructed-response items it cannot earn the method credit for you, so you still show the setup and steps. Treating the calculator as a check rather than a crutch keeps you from leaning on it where it cannot help, including the entire no-calculator session.

Try this

Q1. Is the midpoint formula on the reference sheet?

• Cue. No; memorize it.

Q2. Which is on the sheet: the volume of a cone or the slope formula?

• Cue. The volume of a cone.
