# Desmos Online Calculator

## Overview & Implementation

Desmos online calculators, which include a four-function, scientific, and graphing calculator, are available free to the public. The online calculators can be accessed with a computer, tablet, or other personal device.

Beginning with the spring 2019 test administration, the revised Standards of Learning assessments measuring the 2016 *Mathematics Standards of Learning* that are administered online will include access to Desmos Virginia versions of the online calculators. Grades 4 and 5 Mathematics tests will have the Desmos Virginia Four-Function Calculator in the tool bar for the calculator active part of the test. The Grades 6 and 7 Mathematics tests will have the Desmos Virginia Scientific Calculator in the tool bar for the calculator active parts of the test, and the Grade 8 Mathematics test will have the Desmos Virginia Scientific Calculator in the tool bar for the entire test. End-of-Course (EOC) mathematics tests will have the Desmos Virginia Graphing Calculator available for the entire test. Students will continue to have the traditional four-function calculator available in the tool bar in all online science assessments.

Initially, the VDOE’s transition plan for the implementation of the Desmos Virginia Calculators in the new online mathematics assessments included an expectation that students would use *only* the Desmos Virginia calculators during SOL test administrations beginning in the 2019-2020 school year. As announced in Superintendent’s Memo #043-19-This is a Word document. on February 15, 2019, based on feedback from school divisions, the VDOE is extending the transition period to the Desmos Virginia Calculators through the 2020-2021 school year.

As a result, school divisions will be permitted to continue to provide one of the hand-held calculators on the list of Approved Calculators for the Virginia Standards of Learning Assessments-This is a Word document. through the Summer 2021 test administration to students taking the online version of the mathematics tests based on the 2016 *Mathematics Standards of Learning*.

The Desmos Virginia Calculators (four-function, scientific, and graphing) that will be embedded into the TestNav application will emulate many of the capabilities of the free, public-facing versions that are available on the Desmos webpage, with a few differences. Teachers and students are encouraged to use and be familiar the Desmos Virginia Calculators.

The public facing versions of the Desmos scientific and graphing calculator are also available as apps that allow users to access the calculator without using Wi-Fi or data.

## Desmos Benefits

Using Desmos as an embedded calculator in the testing environment creates a standardized and consistent testing platform as every student will be using the same calculator on the Standards of Learning assessment. Currently, a variety of different brands and types of calculators are approved for use on Standards of Learning assessments, and this requires school divisions and the Virginia Department of Education to regularly ensure that newly developed features are consistent, equitable, and fair for use on assessments.

The Desmos graphing calculator allows users to view and manipulate multiple representations simultaneously, promoting a deeper conceptual understanding of mathematics. Desmos has features that promote student inquiry and help students understand the rich connections and complexity of mathematics. Today’s students are connected to technology through the use of smartphones, tablets, and other devices. The ability to leverage Desmos as a form of instructional technology that melds into the current ways students are accessing information can translate to higher student engagement and meaningful math inquiry.

Desmos is currently available on assessments in a number of states and is now included as an embedded tool on the calculator portion of the new digital SAT, PSAT 10, and PSAT 8/9. The College Board has created a Student Digital Test Preview which includes the link to the Desmos graphing calculator, along with options for accessible testing features.

## Calculator Accommodations

Individualized Education Program (IEP) teams will continue to determine a student’s eligibility to use a handheld calculator other than a VDOE-approved calculator including the Desmos calculator. Currently the student's IEP team must complete the Calculator Accommodation Criteria form-This is a Word document. to document the student's eligibility to use a handheld calculator other than those on the approved calculator list. The Calculator Accommodation Criteria form will be used to determine eligibility for the use of any handheld calculator. To use a particular calculator, but the calculator has additional mathematical capabilities that the student does not require, the school division will submit a Special Assessment Accommodation Request and the completed Calculator Accommodation Criteria form-This is a Word document. to the VDOE.

## VDOE Resources

The Virginia Department of Education, as part of its work to support the implementation of the 2016 *Mathematics Standards of Learning,* has resources and webinars that include Desmos as an instructional technology tool in mathematics classrooms. Development of additional VDOE Desmos resources is in progress. The use of Desmos was highlighted in the 2018 VDOE Fall Mathematics Institutes. In addition, Desmos provides many free, online tutorials and resources for teachers and students.

2016 Mathematics SOL Practice Items in the TestNav8 online test delivery software have been updated to provide access to the appropriate Desmos Virginia Calculator. School divisions are encouraged to begin using Desmos in mathematics instruction.

## SOL Practice Items

Mathematics practice items available in the TestNav online test delivery software will be updated in fall 2018 to provide access to the appropriate Desmos online calculator. School divisions will be notified when this update occurs and are encouraged to begin using Desmos in mathematics instruction.
