### Systems of Equations: Scratch

Emphasis: Algebra Creator: Ashley Tewes        Twitter: @ashleyanntewes Given two lines in slope-intercept form, students will create a program that will find the intersection point between the lines. View Lesson Here

### Hypnotic Squares: Scratch

Emphasis: Geometry and Measurement Creator: Selim Tezel        Twitter: @SelimTezel Students will use their understanding of inverse trigonometry and the Pythagorean Theorem to make a spiraling square pattern. View Lesson Here

### 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

### Graphing Slope-Intercept Form: Scratch

Emphasis: Algebra Creator: Mike Larson        Twitter: @boundsofoutmath This program allows the user to type in a linear equation, then the program graphs the line. 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…

### The Coordinate Plane: Scratch

Emphasis: Measurement and Geometry Creator: Erik Nauman        Twitter: @openblackboard Aim to correctly guess the location of the green square using coordinates. The closer you are the more points you earn. View Lesson Here

### Subtracting Integers Race Game: Scratch

Emphasis: Number and Operation Creator: Ashley Tewes        Twitter: @ashleyanntewes Race to the finish line against the computer. The only way to advance is by correctly answering subtraction questions. View Lesson Here

### 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

### Recipe Proportion Calculator: Scratch

Emphasis: Number and Operation Creator: Ashley Tewes       Twitter: @ashleyanntewes Choose a recipe you love! Then choose how many guests you are cooking for. The program will calculate the amount of each ingredient you need based on the number of guests. View Lesson Here

### Coin Flip: Scratch

Emphasis: Data and Probability Creator:Â Ashley TewesÂ  Â  Â  Â  Twitter: @ashleyanntewes Simulate a simple coin flip in Scratch by totaling the number of heads and tails flipped. Next, calculate the experimental probability of flipping either heads or tails after each flip. View Lesson Here
