Desmos Graphing Calculator vs QuickMark

Explore math with the fast and powerful Desmos Graphing Calculator. Plot any equation, from lines and parabolas to derivatives and Fourier series. Add sliders to demonstrate function transformations, create tables to input and plot data, animate your graphs, and more—all for free. Features: Graphing: Plot polar, cartesian, or parametric graphs. There’s no limit to how many expressions you can graph at one time—and you don’t even need to enter expressions in y= form! Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph. Tables: Input and plot data, or create an input-output table for any function. Statistics: Find best-fit lines, parabolas, and more. Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window. Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Tap the gray points of interest to see their coordinates. Hold and drag along a curve to see the coordinates change under your finger. Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. It can handle square roots, logs, absolute value, and more. Inequalities: Plot Cartesian and polar inequalities. Accessibility: Read and edit math using a screen reader or a refreshable Braille display, and use audio trace to explore graphs and data through sound. Offline: No internet access required.

Keep track of the little things before they become big things. QuickMark is a simple student event tracker built for teachers who need a fast way to record what happens throughout the school day and remember what needs to happen next. Log an event in seconds, keep a running student history, and let QuickMark turn repeated events into actionable follow-ups. QUICKLY LOG STUDENT EVENTS: Select a student, tap an event, and you're done. Track positive moments like great sportsmanship, helping a classmate, or personal bests, as well as everyday events like tardies, uniform issues, phone use, or behavior concerns. Create your own custom event types to fit your classroom. AUTOMATIC FOLLOW-UPS: Create simple rules that turn repeated events into TO-DOs. If three phone incidents mean it's time for a parent contact, QuickMark can automatically add that follow-up to your list so you don't have to remember it yourself. A USEFUL HISTORY FOR EVERY STUDENT: See a student's events, notes, follow-ups, and class history in one place. Add notes when extra context matters, manually adjust counts when needed, and keep previous class history available without carrying old counts into a student's fresh start. FIND WHAT MATTERS: Sort and filter students by event counts, event type, follow-up status, and time period. Quickly answer questions like, "Who has had uniform issues this week?" or "Which students still need a follow-up?" BUILT AROUND YOUR CLASSES: Organize students by class, support students enrolled in multiple classes, and archive old classes when a semester or school year ends. QuickMark preserves useful history while keeping your current rosters clean. IMPORT YOUR ROSTERS: Get started quickly by importing student rosters from CSV or Excel files. QuickMark can recognize returning students so their previous history stays connected while their new class starts fresh. NOTES AND STUDENT PHOTOS: Add context to individual events and TO-DOs, and optionally add student photos to make finding the right student even faster. MADE FOR THE TEACHER, NOT THE SIS: QuickMark isn't trying to replace your school's student information system, gradebook, or learning platform. It's a lightweight tool for the information teachers often need to capture in the moment: what happened, how often it has happened, and what needs to happen next. Spend less time trying to remember the small details and more time acting on the ones that matter.
