# Whistler: Gallery of Applets

This is a list of applets I’ve used recently with my classes. Geogebra applets might take a few moments to load if the wifi is being super-shared.

# Play

Symmetry

Puzzles

Plot the points

Line Segments

Ordered Pairs Linear Relation

# Exploring a concept:

Pythagoras’ Theorem

Right angled Triangles

Visual Trig Values

Estimate a side/angle

Estimate (multiplication)

# Practice a Technique

Expand, Gather, Factor

Trigonometry: Calculate a side length

Calculate the equation of a line through two points

Solve a system of two equations

Straight Edge and Compass Construction

Sequences of Circles

Star Diagrams

Exploding particles

# Classroom Implementation

It takes more than just the resource. For learning to occur with the laptops as a resource, it’s helpful to create a picture that works – laptop at the side of the desk, notebook and pencil at the front of the desk. About a quarter of my lessons are ‘laptop lessons’, it is important to me that a significant portion of lessons are ‘laptop free’.

For exploring a concept, I find that having an identifiable end to the task is helpful, and so I generally include a reasonably short list of questions.

For developing skills, I use these applets as a basis of assessment for half of the course grade and allow the students to self assess. Each student gets their own questions; they correct and trouble shoot as they go and my key question to them when they tell me they’ve mastered a skill is whether or not they think that will be able to recognise and solve a similar problem in a test the following week.

I don’t tend to use geogebra when requiring the students to use the skills alongside other skills in a variety of dissimilar problems. However, I do find geogebra useful when asking student’s to create some of their own math and to think their way through conceptual questions. I will often use geogebra classic and have student’s create their own account with their school email, or use one of the ‘create your own’ tasks.
