A list of MathyCathy's Desmos Activities and Card Sorts

Thank you to all who inspired and helped create these resources!

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Complete The Squares

An activity by Nerissa Gerodias edited with love. A visual introduction to completing the square using algebra tiles, Desmos Sketch, and a twist on Desmos Card Sort.

Preparing for TEKS A.8(A)

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Squares and Square Roots

Students often confuse the concepts of "square" and "square root". This Card Sort provides numerical expressions, word phrases, and red images that will help students make connections between concrete visuals and abstract notation.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Polygraph - Rectangles

At first glance, these are just rectangles, but many perimeters and areas have been strategically chosen. As students play, my hope is they will gain a deeper understanding of perimeter, area, and their independence.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Critter Patterns Activity Builder

"Visual Patterns" guide students through the process of generalizing patterns algebraically. This activity focuses on linear patterns.

Inspired by:

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | When Are Equations True?

When are the equations true?

This Card Sort was adapted from the Mathematics Assessment Project CLASSROOM CHALLENGES "Solving Linear Equations in One Variable".

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Expressions Mash-Up

Edited with love by Desmos Teaching Faculty
In this activity, students sort cards to strengthen their understanding of multiple representations, including: algebraic expression, verbal description, table of values, and algebra-tile model.

After the card sort, students discuss whether a given student has sorted two pairs of cards correctly, and in the process consider equivalence and commutativity.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Number Properties Sort

Basic number properties card sort. Beware of false "BOGUS" properties! A quick pre- or post-assessment.

TEKS 6.7(D)

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Function or Not?

Students decide whether various representations are functions or not, and sort them accordingly.

To follow up, have students create their own tables, mappings, and graphs that DO represent and DO NOT represent functions using this Nearpod quick-check, inspired by tasks shared on openmiddle.com:

TEKS 8.5(G)

Sep 11, 2016 - teacher.desmos.com - 404
Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Real Number Sort: ALWAYS, SOMETIMES, NEVER

Once students have learned about various classifications in the real number system, this task encourages deeper thinking about the relationships between these numbers.

Individuals, pairs, or small groups sort the statements in the appropriate categories of ALWAYS being true, SOMETIMES being true, or NEVER being true.

The best part about tasks like this is the student discourse that occurs. Be sure to circulate and listen to students’ arguments and justifications as they sort.

TEKS 8.2(A)

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Twin Puzzles

Edited with love by Desmos Teaching Faculty
In this activity, students use sketch to solve "twin puzzles" as a way to practice their order of operations skills. Teachers can use the overlay feature in the teacher dashboard to assess the class at a glance and to facilitate class-wide error analysis discussions, or the response view to identify individual students who need additional support.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Des-Draw

Edited with love by Desmos Teaching Faculty
While the original Des-Man is receiving a makeover, give Des-Draw a try!

My hope is to leave it open to encourage students' creativity while helping them brush up on restricting the domain and range of various functions, gently reminding them that using inequalities can create some rad shading.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Card Sort: Integer Chips

Using a Desmos Card Sort as a "virtual manipulative" platform was an idea Michael Fenton and I talked about. Here's his fine work after a chat about using "Integer Chips" in a "Card Sort"

Thanks so much, Michael!

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Reflections

This activity focuses on 2-D reflections over the x-axis and y-axis, with an extension activity reflecting a figure over y = x. CCSS 8.G.A.3; TEKS 8.10(A)

Sep 14, 2016 by Cathy Yenca - teacher.desmos.com - 416
Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Zero and Negative Exponents

Using Desmos "Sketch", students generate patterns to explore zero as an exponent and negative exponents.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Domain and Range Practice

Thanks to Suzanne von Oy @von_Oy for creating the original task!

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | TRUTH or LIE? Domain and Range From a Graph

A math spin on the "Two TRUTHS and a LIE" strategy, inspired by Jon Orr, @MrOrr_geek.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | #WODB Equations Warm-Up

Which One Doesn't Belong? Let's start a "math fight"!

In this brief activity, students are given four equations with variables on both sides of the equals sign. Using Desmos Card Sort, students must take a stand on which equation they believe doesn't belong, and justify this choice.

Students will see what other students choose, and consider different opinions and justifications. Additionally, students have the opportunity to create their own #WODB task to share.

Which one do YOU think doesn't belong? Why?

#WODB inspired by http://wodb.ca

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Quadrilaterals: ALWAYS, SOMETIMES, NEVER

Once students have learned about special quadrilaterals, this task encourages deeper thinking about the relationships between them.

Individuals, pairs, or small groups sort the statements in the appropriate categories of ALWAYS being true, SOMETIMES being true, or NEVER being true. Then, students attempt to sketch quadrilaterals given various constraints.

The best part about tasks like this is the student discourse that occurs. Be sure to circulate and listen to students’ arguments and justifications as they sort and sketch.

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Solving One-Step Equations

Here's an intro activity on solving one-step equations that includes opportunities for organizing work using "Sketch" and "Card Sort" and error analysis using "Sketch". A silent video helps students visualize how a balanced scale can model solving an equation.

For more practice on equivalence with numerical expressions (and an Order of Operations twist) check out Twin Puzzles here:

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Similar Rectangles

Let's explore similar rectangles, their perimeters, and their areas!

Desmos Creations & Collaborations #ActivityBuilder #CardSort #Polygraph | Is It...?

A triple card sort to help students practice classifying functions:

  • that are and are not linear
  • that are and are not parallel to a given line
  • that are and are not perpendicular to a given line

Grab some scrap paper folks. You're gonna need it.
