The 8th graders made "Parabola Art" using the Desmos platform we use as a curriculum.  This is part of their unit study on Quadratic Functions.
8th Graders worked with play-doh and real bagels to explore the "Mobius Bagel."  This was an introduction to the work of Eugenia Cheng.  Video link here if you're interested.
7th Graders worked in pairs on a Formative Assessment Lesson (FAL), where they complete a card sort matching a situation to the graph of a function that could represent it, then match those graphs/contexts to an equation. 
8th graders worked on their End of Unit Synthesis Project (Unit: Linear Systems and Inequalities) by creating and branding their own Trail Mix.  Students created nutritional constraints and chose ingredients for their own trail mix, then had to graph inequalities in order to make a trail mix that met all of their specifications.
8th grade students worked on a STEM challenge---using 20 sheets of paper only (no scissors, tape, glue, etc), build the tallest freestanding tower possible.
2nd and 8th graders partnered up for a Math activity in the gym.  2nd graders took time to poll the school with a survey, collecting categorical data, and then worked with the 8th graders to turn the data into a visual representation in the form of a bar graph and table.
5th Grade worked on an SEL / Cartesian Plane activity, plotting emotions on a cartesian plane and sharing a time when they felt that emotion with their partner.
5th graders worked on Order of Operations this week as a welcome back.  Pictured above, they are writing their ideas for equations from our "Tricky 24" activity, a variation on "Four 4s," which we did the day prior.  The idea is that using only the digits 1,2,3 and 4, in addition to any operation, they must come up with an equation that equals the numbers 1-24.
8th Grade worked with their 2nd grade buddies this week on an arts and crafts activity creating a snow-globe.
8th Graders participate in the Stock Market Game, where they receive a virtual $100,000 to invest in the real stock market. The virtual investments behave in real time with the actual stock market. 
 
On Thursday, 8th graders met virtually with a Financial Advisor from Raymond James to hear a presentation/Q&A on the Stock Market, philosophy if investing, and top tips for young investors.
