Interactive Applets
Labs you can actually drive
Drag points, slide values, and knock out missions. Custom applets run here. Desmos and GeoGebra open in a new tab when you want a full graphing calculator.
Slope and Rate of Change
Both examsDrag two points. Watch rise, run, slope, and the equation y = mx + b update together.
NY-8.EE.5 · NY-8.EE.6 · AI-F.IF.6
Solving Equations
Both examsBalance a linear equation one inverse operation at a time. See when you get one, none, or infinitely many solutions.
NY-8.EE.7 · AI-A.REI.3
Systems of Linear Equations
Both examsAdjust two lines and watch their intersection — the solution of the system — move in real time.
NY-8.EE.8 · AI-A.REI.6 · AI-A.REI.11
Function Notation
Algebra I RegentsSend values through a function machine and connect f(a) = b to a point on the graph.
AI-F.IF.1 · AI-F.IF.2
Transformations
Grade 8 State TestTranslate, reflect, rotate, and dilate a triangle. Compare the pre-image and image coordinates.
NY-8.G.1 · NY-8.G.3 · NY-8.G.4
Exponents and Scientific Notation
Grade 8 State TestSlide an exponent and watch a number expand or collapse into scientific notation.
NY-8.EE.1 · NY-8.EE.3 · NY-8.EE.4
Square Roots and Irrationals
Grade 8 State TestPlace √n between consecutive integers and see it on the number line.
NY-8.NS.2 · NY-8.EE.2
Pythagorean Theorem
Grade 8 State TestDrag the legs of a right triangle. Watch a² + b² and c² stay in lockstep.
NY-8.G.6 · NY-8.G.7 · NY-8.G.8
Scatter Plots and Best Fit
Both examsAdd points, then fit a line. Interpret slope in context and watch residuals.
NY-8.SP.1 · NY-8.SP.2 · AI-S.ID.6
Quadratic Forms and Graphs
Algebra I RegentsToggle among standard, vertex, and factored form. Track vertex, roots, and axis of symmetry.
AI-F.IF.7 · AI-F.IF.8 · AI-A.SSE.3
Linear vs Exponential vs Quadratic
Algebra I RegentsOverlay three models on the same axes and compare how they grow.
AI-F.LE.1 · AI-F.IF.9
Volume: Cylinder, Cone, Sphere
Grade 8 State TestAdjust radius and height. Compare a cone to a cylinder with the same base and height.
NY-8.G.9
