To recap, I have uploaded a past paper to my Moodle course and have included an online discussion forum that allows students to discuss problems online between themselves and me.
One of the questions my students seemed to get stuck on involved a ladder pitched against a vertical wall. You are given the ladder's length and the distance between the bottom of the wall and the foot of the ladder. The question asks you for the height of the top of the ladder from the ground. It's a Pythagorean Theorem question, and my idea is to create a Moodle course specifically covering the Pythagorean Theorem. My Moodle admin has created the course and I've been given the teacher role. In the rest of this book, we'll be working together to create this course.
