Desmos offers curated collections of activities by grade that are translated into multiple languages and are well-suited to asynchronous, distance learning.

Complete math activities from Tools for Teachers (teacher access only).

Use calculators during synchronous or asynchronous teaching and learning activities.

To help students and teachers prepare for assessments-and to support delivery of tests and quizzes in classrooms-Desmos developed a suite of 'Test Mode' apps that match the configuration that students will encounter on test day.

Practice sample assessment items with the Desmos Calculators on the Smarter Balanced Sample Items Website. Calculator sharing is now enabled To share your graph as a URL, click the 'Share' button and copy the URL.

Desmos has assembled a collection of unique and engaging digital activities teachers can use with students.

text can be done using Desmos, Geogebra, or a TI/Casio graphing calculator.

Create graphs to download, print, emboss in braille, or share electronically. You will use the graphing program named Graphing Calculator (GC) extensively.

Learn how the calculator supports students on the assessment with the Tools for TeachersвЂ™ Accessibility Strategy: Calculator.

Teach, learn, and explore mathematical concepts. Districts must ensure that each student has a graphing calculator to use when taking the STAAR grade 8 mathematics, Algebra I, or Algebra II assessments.

The Smarter Balanced Desmos calculators is also compliant with the latest web accessibility standards. Choose from Cartesian or polar grids, select angle measurement in degrees or radians, and use the embedded keyboard to enter equations. The calculators allow students to adjust font size if they prefer larger print. This browser-based calculator provides a platform for users to perform calculations, share, and create interactive Whiteboard resources. The calculators provide support for students who have low vision or students who have difficulty with visual perceptual skills. Paired with a refreshable braille display, these features offer students who use braille the same opportunity as their peers to access an online calculator. Fully supporting keyboard navigation, the calculators communicate with screen readers, which voice additional cues to indicate a studentвЂ™s location within an expression or within a graph (numerator or denominator, superscript or subscript, baseline, points on the graph, etc.). Students can then emboss their graphs and share print or braille versions with classmates and teachers. The pitch of the tone increases or decreases depending on the shape of the wave or graph. Students who are blind can create their own graphs in real time and determine the shape of a graph through audio trace. Students who are blind can read and write equations using the two mathematical braille codes used in the United States: Nemeth and Unified English Braille (UEB). Most of them much prefer Desmos over TI graphing calculators. Compare the equation Desmos generated to yours. I have my students use Desmos as their main calculation and data analysis tool in my high.

To have Desmos create an equation of best fit, in the input bar, add a new equation y1~bx1^2+cx1+d.

Adjust your sliders until you get the highest possible value for RВІ.

Desmos uses y 1 to represent the y-value in a data table and x 1 to represent the x-values in a table. The Desmos graphing calculator allows users to view and manipulate multiple representations simultaneously, promoting a deeper conceptual understanding of. To have Desmos calculate your R 2 value in a new input line type y1 ~ a(x1-h)^2+k. The closer R2 is to 1, the better the curve matches the data.

The R-squared value is a statistical measure of how close the data are to a fitted regression line.

To do so, click on the gear icon to Edit List. You will likely need to change your slider settings.

Adjust the values of the sliders until the graph of the equation most closely fits your data points.

In the input area, type y=a(x-h)^2 + k and press Enter.

In the example above, the data appears to be quadratic.

Decide what type of equation the data represents.

Modify your x, and y values to reflect your data.
