Once students have learned about various classifications in the real number system, this task encourages deeper thinking about the relationships between those classifications. Individuals, pairs, or small groups sort the statements according to whether they are ALWAYS, SOMETIMES, or NEVER true. Be sure to circulate and listen to students' arguments and justifications as they sort.

This activity is intended to help you get to know your students and for them to get to know each other. Consider spreading screens out over the course of several days or using this activity all at once. Inspired by and with gratitude to Julia Anker, Howie Hua, Sara VanDerWerf, and The Abolitionist Teaching Network.

In this Desmos-ified treatment of a classic math problem, students will first construct expressions with numbers to determine the number of tiles that border a pool. Then they'll use those numerical expressions to help them write an expression with VARIABLES.

Students sort cards to strengthen their understanding of equivalent expressions. In particular, this activity uses visual representations of algebraic expressions to help students see that expressions are equivalent when they correctly count the same thing.

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.

In this lesson, students interpret points in a scatter plot within a context and add points to a scatter plot given information about an individual in the population. Students spend a lot of time looking at the details of a scatter plot, naming the quantities represented in a scatter plot, and focus…

In this activity, students build coordinate plane proficiency through a guess-the-location-style game. We also have a version for primary grades that addresses only the first quadrant: https://teacher.desmos.com/activitybuilder/custom/58f53fc09c2d690fce53563a French translation courtesy of Stéphanie Boucher: https://teacher.desmos.com/activitybuilder/custom/59f0decf5180a30c1a535bae

In this activity, students will encounter a series of challenges, each asking them to graph a point on the bullseye of a target. They will plot points in all four quadrants, first by plotting points using a table and then by using ordered pairs. Activity inspired by Nathan Kraft.

Students are introduced to transformations of plane figures and are asked to describe these movements in everyday language. While students are not expected to use formal math vocabulary yet, this lesson provides the intellectual need for agreeing upon common language and gives students a chance to experiment with different ways of describing some transformations in the plane (MP6).
