### Approximating Pi with Inscribed Area: Scratch

Emphasis: Geometry Creator: Jason Slowbe and Mike Larson     Twitter: @boundsofoutmath Create an algorithm that approximates pi using the area of inscribed polygons in a unit circle. View Lesson Here

### Right Triangle Check: Scratch

Emphasis: Geometry Creator: Ashley Tewes     Twitter: @ashleyanntewes The user types in three side lengths of a triangle. The program will tell the user if the triangle lengths create a right triangle or not.   View Lesson Here

### Find My Area: Scratch

Emphasis: Geometry and Measurement Creator: Ashley Tewes     Twitter: @ashleyanntewes Students will create a program that will find the area of different polygons; such as square, rectangle, triangle, rhombus, and trapezoid. View Lesson Here

### Solids of Revolution: Beetle Blocks

Emphasis: Geometry and Measurement Creator: Mike Larson        Twitter: @boundsofoutmath Students will understand the structures of curved shapes as being products of revolution around an axis. View Lesson Here

### Solids of Extrusion: Beetle Blocks

Emphasis: Geometry and Measurement Creator: Mike Larson        Twitter: @boundsofoutmath Students will understand the structures of prisms and other extruded shapes with congruent and parallel bases. View Lesson Here

### Pythagorean Theorem Solver: Scratch

Emphasis: Geometry and Measurement Creator: Ashley TewesÂ  Â  Â  Â  Twitter: @ashleyanntewes Students will create a program that will solve for the missing side length of a right triangle. The player will choose which side of a right triangle they want to solve for, type in the side lengths they know, then the program will…

### Growing Patterns Translations: Scratch

Emphasis: Algebra, Geometry and Measurement Creator: Jim Cash      Twitter: @cashjim Students will use pattern recognition to grow a visual pattern with translation and variables. View Lesson Here

### Geoguessr Simulation: Scratch

Emphasis: Geometry and Measurement Creator: Will AbbottÂ  Â  Â  Â  Twitter: @MrAbbottMath Have you ever played the game Geoguessr? Google Earth drops you in a random location on Earth and your goal is to guess where you are. The program then tells you how close/far you are from the destination. Geoguessr simulates this by using…

### Playful Polygons: Scratch

Emphasis: Geometry and Measurement Creator: Dan AndersonÂ  Â  Â  Â  Twitter: @dandersod Students will draw, using the pen tool, different polygons. They will start with a square, then a triangle, then some challenge shapes. The designs will be based on the angles of the shapes. View Lesson Here
