The transition to the Digital SAT\u00ae<\/strong> (DSAT)<\/strong> introduces Desmos\u00ae<\/strong>, a built-in graphing calculator that replaces the need for a handheld device. Unlike traditional calculators, Desmos\u00ae offers dynamic graphing, equation-solving, and statistical tools<\/strong>, making it a powerful asset for test-takers.<\/p>\n

Horizon Education integrates Desmos\u00ae into our <\/strong>SAT\u00ae prep platform<\/strong><\/a>, allowing students to practice using the same tools they\u2019ll encounter on test day. By incorporating Desmos\u00ae<\/strong>-based questions and strategies into instruction, teachers can ensure students are comfortable and confident using Desmos before test day.<\/p>\n

Why Use Desmos\u00ae on the Digital SAT\u00ae?<\/strong><\/h2>\n

Since Desmos is integrated into the Digital SAT\u00ae platform<\/strong>, students don\u2019t need to bring a separate calculator. Key advantages include:<\/p>\n

    \n
  • Graphing capabilities<\/strong> for equations, functions, and inequalities.<\/li>\n
  • Quick calculations<\/strong> for exponents, logarithms, and statistical data.<\/li>\n
  • Dynamic sliders<\/strong> to adjust variables and visualize patterns.<\/li>\n
  • Time-saving tools<\/strong> that streamline problem-solving.<\/li>\n<\/ul>\n

    Should Students Bring Their Own Calculator?<\/strong><\/h3>\n

    While Desmos is provided, students can still bring an approved, handheld calculator:<\/p>\n

      \n
    • Graphing calculators (e.g., TI-84, Casio fx-9750GIII)<\/li>\n
    • Scientific calculators (e.g., TI-30XS Multiview)<\/li>\n
    • Basic four-function calculators (for simple calculations)<\/li>\n<\/ul>\n

      Key Desmos Strategies for the Digital SAT\u00ae<\/strong><\/h2>\n

      1. Solve Systems of Equations Instantly<\/strong><\/h3>\n

      Instead of using substitution or elimination<\/strong>, students can graph equations and find intersection points in seconds.<\/p>\n

      How to Do It:<\/strong><\/p>\n

        \n
      1. Enter both equations into Desmos.<\/li>\n
      2. Identify the intersection point<\/strong>\u2014this is the solution.<\/li>\n
      3. Click the point to see precise values.

        \"\"<\/div>\n<\/figure>\n

        \ud83d\udca1 Teacher Tip:<\/strong> Use practice problems where students solve systems both algebraically and graphically<\/strong>, so they know when Desmos is the best choice.<\/p>\n

        2. Graph Functions for Quick Answers<\/strong><\/h3>\n

        Rather than solving quadratics or polynomials manually, Desmos allows students to visualize key points instantly<\/strong>.<\/p>\n

        How to Do It:<\/strong><\/p>\n

          \n
        • Input the function (e.g., y = x^2 – 5x + 7).<\/li>\n
        • Desmos highlights vertices, intercepts, and intersections<\/strong> automatically.<\/li>\n
        • Click points for precise values.<\/li>\n<\/ul>\n
          \n
          \"\"<\/div>\n<\/figure>\n

          \ud83d\udca1 Teacher Tip:<\/strong> Assign students practice questions where graphing the function first<\/strong> leads to a quicker answer.<\/p>\n

          3. Visualize Inequalities<\/strong><\/h3>\n

          Desmos makes solving inequality questions faster and more intuitive<\/strong> by shading solution regions.<\/p>\n

          How to Do It:<\/strong><\/p>\n

            \n
          • Enter an inequality (e.g., y > 2x + 3).<\/li>\n
          • Desmos will shade the solution area<\/strong> automatically.<\/li>\n
          • For multiple inequalities, the overlapping shaded area<\/strong> represents the solution set.<\/li>\n<\/ul>\n

            \ud83d\udca1 Teacher Tip:<\/strong> Have students compare algebraic vs. graphical solutions<\/strong> to reinforce conceptual understanding.<\/p>\n

            4. Use Sliders to Adjust Variables<\/strong><\/h3>\n

            The slider tool<\/strong> helps students dynamically test different values in equations.<\/p>\n

            How to Do It:<\/strong><\/p>\n

              \n
            • Input an equation with a variable (e.g., y = ax + 3).<\/li>\n
            • When prompted, add a slider for ‘a’<\/strong>.<\/li>\n
            • Adjust the slider to see how the graph changes.<\/li>\n<\/ul>\n
