Scratch mathematics is a fun way to better understand algebra and co-ordinate geometry not only by visualising it but by creating sketching and problem solving algorithms.
Coding ties in with Algebra through the use of variables to store and transform information. These variables will be used to create and solve equations and also to investigate factorisation and prime numbers.
Coding ties in with co-ordinate geometry through user interfaces (the very screen you are looking at right now) this screen is a Cartesian two dimensional plane where every single pixel is a unique co-ordinate. These pixels are essentially the same as squares on a plotting paper and so we can use them to plot various functions, intersections points and axis intercepts.
What you can do with this knowledge?
If you are a high school student you can gain a novel insight into your most important maths skills and come to realise their value in applying them to computer programs
If you are a teacher you have just acquired a capacity to create some amazing interactive activities for algebra and co-ordinate geometry. Beyond this you can create automated quizzes which your students can use to test their skills.
If you are budding game designer you can better understand the equations that govern the movement of objects and so begin creating basic physics engines
How long will the course take?
This course can be completed in approximately 4 hours by someone proficient in Scratch, a Scratch novice would need about 6 hours
What else is included?
All the solution files are attached in a zip file inside the very first introductory lecture
Sanjin is a teacher and a robotics engineer with a passion for teaching Coding and Robotics to school aged children. He has spent more than 5 years teaching various age groups in platforms like Scratch, Arduino, Python, Raspberry Pi and Lego Mindstorms.
He is presently working with over 20 schools in Melbourne to help them implement the Digital Technologies Curriculum in a meaningful manner. This means developing learning sequences that help students easily grasp the core concepts of coding and then setting them up with problems that involve higher level computational thinking and integration with various mathematical concepts.
