I am a math teacher from Naperville. I am THE math department at Griggsville-Perry High School.

@numberphile has a really good video on modeling the corona virus. I shared it with my students. I found it really insightful.

[mr.kevinduffy @MKevinduffy]

Been making instructional videos this week with the help of @WeVideo, @edpuzzle, and @YouTube. Starting wednesday, I will be setting up google meets with my students

From #IDEACon2020 , something I am thinking about for my students.

[mr.kevinduffy @MKevinduffy]

Getting ready to go over transformations of trigonometric functions. This is all thanks to the @Desmos training I received at #IDEAcon!!!

Check out this @Desmos activity: Trigonometric Function Sandbox! https://t.co/0sSvPLI1oo

It has been a while...off to Idea Con 2020 (formerly ICE).

[mr.kevinduffy @MKevinduffy]

Going to be giving my colleagues the summary of the ICTM

[mr.kevinduffy @MKevinduffy]

Been looking into @Desmos, always been a @geogebra fan myself. Both have tremendous benefits from what I can see.

MAP testing is 99.9% complete. I am now looking at results and deciding how my units will look the rest of the year.

[mr.kevinduffy @MKevinduffy]

Finishing up my schools first session of MAP testing today.

New magnet sets from my awesome superintendent. Geometry students will be using these in the AM on Tuesday!

[mr.kevinduffy @MKevinduffy]

Been implimenting notice/wonder discussions I learned about at the @MathICTM this year. It was the presentation by @snhendr and @mathwithtomkiel that proved to be the game changer

Gearing up for day 2 of my newly implemented flipped classroom in precalculus

@RachelFruin A very well thought out article with some truth. However, I do believe we have a country whose curriculum is dictated not by real world situations, but by what they will see in an equivalent or higher class in college. It was interesting to put data to it though.

[mr.kevinduffy @MKevinduffy]

Might be kinda hard to see, but I did my first scavenger hunt today with my algebra 2 students (courtesy of a session at @ictm2019) the students were very active and engaged

[mr.kevinduffy @MKevinduffy]

Interactive for statistics activities. This helps see how mean, median and mode interact with the distribution of a graph.

[mr.kevinduffy @MKevinduffy]

Big shout out to https://t.co/jfh275rG8F, they have great interactives. My geometry class used the Cross Section Flyer today to help visualize cross sections of 3 dimensional shapes. I also use the function revolution interactive for integrals in calculus and also use the plop it
