Gsp5 rifle3/5/2023 ![]() ![]() One single shot can mean the difference between feeding your family or going hungry. Precision weapons have been used to assassinate political figures, high ranking military leaders, and have started and ended many major wars and battles. Used by Police & Military: Remington Model 700 SPS Tactical AAC-SDįirst off, understanding the importance of precision shooting is, in my opinion, the most interesting thing in this sport to begin with.Not too long after, I learned about The Math Forum – an amazing resource for math teachers and students founded at Swarthmore College and now seems to be hosted by Drexel University. To this day, it remains my favorite piece of educational software. I started exploring/playing with Geometer’s Sketchpad in 1994 as an undergrad at Bryn Mawr College. – Parallelogram Translations by Cathi Sanders of Punahou School – Triangle Rotations by Janet Mae Zahumeny of Roselle Park High School Then we rotated this altered triangle 60 degrees 6 times to form a hexagon before we tessellated the whole hexagon.įor my tessellation activities, I use two online lesson plans that I located years ago: I showed the kids how to use Geometer’s Sketchpad to build an equilateral triangle, alter one side, and rotate that side 60 degrees to create a new shape. Because of the nature of our curriculum, the students had similar discussions in Art and Spanish among other subject areas. Escher’s artwork, and we talked about how classic Islamic art would rely on geometric patterns rather than animal or human forms. On the third day, I stepped in, and we talked about how a tessellation is a pattern of repeating shapes that do not overlap and have no gaps in between. ![]() For example, rotating 90 degrees meant that (x,y) become (-y, x). Again, students analyzed how rotating the figure affected the coordinates of the original shape. The second day, Katie showed how to rotate a polygon 90, 180, 270, and 360 degrees around the origin. For example, reflecting over the x-axis means (x,y) becomes (x, -y). Students explored the resulting coordinates and stated the formula as an algebraic expression. On the first day of the mini-unit, Katie led a class on reflecting a polygon over the x-axis and y-axis. We briefly went over how to make transformations and use specific menu options in Geometer’s Sketchpad, as Katie is one of those independent teachers that initially explores on her own rather than rely on my tutelage. Before Winter Break, we met and planned a 3-day mini unit for our first week back It bridged a unit on solving equations with her next unit on the Cartesian Plane. ![]() Katie Hildebrandt, often confused from behind for one of her students ( à la Macaulay Culkin), is an energetic and supportive member of the 6th grade team and has a natural gift for breaking down mathematical concepts for her students. (All of our K-8 Themes and Concepts can be found here. It is one of my favorite integrated projects. Then, the students take their creations to Art class and build a physical model out of clay and/or paper. For the last few years, I’ve worked with the math teachers to show the kids how to design tessellations on the computer. At The School at Columbia University, 6th graders study Islam and Mecca as part of the grade-wide theme: How History Shapes my Identity. I spent a few days this week with the 6th grade math teachers/students. ![]()
