Congratulations to the entire cast and crew of Percy Jackson. You completely rocked it. This little fan (and big fan too) adored the show and you brought her heroes to life. @NCHS_CT

Here is the last picture with all the chess pieces since they are finished printing. These were designed in @Desmos part of a summative project on integrals, calculated the volume of them, imported into @tinkercad revolved, tinkered with and then 3D printed. @NCHS_CT

9 chess pieces printed so far, 3 more printing today! I love how they are coming out! @Hernbergler @NCHS_CT

The first 3D printed chess piece from this year!! Thank you @Hernbergler @NCHS_CT

Awesome collaboration with @Hernbergler to 3D printing in Calculus today. Thank you for all your hard work helping us 3D print our chess pieces we designed earlier in the year. @NCHS_CT

Look at these chess pieces that Calc Ss designed! They calculated the volume of them and after APs @Hernbergler will be helping us 3D print them! Thank you to Twitter PL that inspired the project (my apologies - I can't remember who at the moment) @NCHS_CT #iteachmath #MTBoS

Today students in H Algebra 2 used @Desmos and sinusoidal regressions to write equations of real world sine and cosine curves. I asked them to start with a google image search of something that had "sine curve vibes" @NCHS_CT #MTBoS #iteachmath

Love a colorful Unit Circle! Building the understanding is more important than any amount of memorization. @NCHS_CT

Coloring a sector with a central angle of one radian in Honors Algebra 2. Nice way to summarize our radian investigation right before break. @NCHS_CT
