We have moved! math247.pbwiki.com

Date: 29 April 2007 - Physics with GeoGebra Activity 3 - Firing the Cannon - Tilting Cannon Do Part 1: Set the Parameters and Fire the Cannon A bit more fun for the user: Learning in this activity: User can set the angle and watch the cannon tilt, the height and the initial velocity and then fire the cannon, follow the trajectory of the cannon ball and have it explode (and see the equations and the data). --- Developers: This is an animated GeoGebra Activity with appearing and dissapearing objects and a rotating object - see GeoGebra Starters.
Date: 19 April 2007 - Activities with GeoGebra Activity 4 - Measuring Length: Many times the young ones don't understand how to measure with a ruler! Use these activities to help them see and do! Guided Activity: Ladybug Walks the Width - Learning to Measure - a set of 6 guided interactive activities to understanding measuring length - for 2nd - 3rd grader - Try it! - Demo Screencast - Download zip (includes practice) Practice Activity: Ladybug Walks the Width - Practice NEW! - practice activity for testing understanding of length - for 2nd - 3rd grader - Try it! - Demo Screencast - Download zip Simple & Small: Interactive Length Measurement Activity for 2nd - 5th Graders! - Try it!
Date: 16 April 2007 - Activities with GeoGebra Activity 3 - Perimeters and Areas of Rectangles or standalone download (zip 1MB) Simple & Small: Interactive Activity for 3-5th Graders!
Date: 8 April 2007 - Algebra with GeoGebra Learning and fun with Quadratics* 1. Vertex and coefficient a - Try it! 2. Vertex and point - Try it! See complete set of exercises here! GeoGebra: Exploring quadratics and parabolas. *IMPORTANT: To properly view these files, you need to download and install these 5 fonts to Windows. To download and use, you will need jsMath and this js file.
Date: 28 March 2007 - Learn and Use GeoGebra Lesson 3 - Sliders, Properties, Text Try the result first! Mathcast with Lesson 3 - watch and do Script for Lesson 3 (pdf) - written directions to the mathcast NEW! GeoGebra file - sample ggb file
Date: 28 March 2007 - Physics with GeoGebra Activity 1a - Firing the Cannon - Exploding Cannonball Do Part 1: Set the Parameters and Fire the Cannon A bit more fun for the user: Learning in this activity: User can set the angle, the height and the initial velocity and then fire the cannon and watch the trajectory of the cannon ball and have it explode (and see the equations and the data). --- Developers: This is an animated GeoGebra Activity with appearing and dissapearing objects so the GeoGebra file is harder to follow than Activity 1 (and still under construction!).
Date: 27 March 2007 - Learn and Use GeoGebra Lesson 4 - Inputs and Disappearing Objects Try the result first! Mathcast with Lesson 4 - watch and do Script for Lesson 4 (pdf) - written directions to the mathcast NEW! GeoGebra file - sample ggb file
Date: 25 March 2007 - Physics with GeoGebra Activity 1 - Firing the Cannon Do Part 1: Set the Parameters and Fire the Cannon Learning in this activity: User can set the angle, the height and the initial velocity and then fire the cannon and watch the trajectory of the cannon ball (and see the equations). --- This is an animated GeoGebra Activity! (still under construction - the ball journeys to the center of the earth ... - but a bit of fun!)
Date: 21 March 2007 - Geometry with GeoGebra Activity 4 - Constructing Parallelograms Do Part 1: Construct a Parallelogram given 2 Sides and the Angle Between Part 1: Short version (for the easily bored student) + pdf handout (with details)NEW! Do Part 2: Calculate the Area of a Parallelogram Constructed from 2 Sides and the Angle Between Do Part 3: Construct a (slightly unstable) Parallelogram given 2 Sides and the HeightNEW! Do Part 4: Construct a (Stable) Parallelogram given 2 Sides and the HeightNEW! Mathcast with Activity 4 - watch and do
Date: 10 March 2007 - GeoGebra Starters JavaScript GeoGebra Functions - Javascript functions for interaction between the html with the ggb file. - Javascript functions for generating random values for slope, angles, etc. pdf file
Date: 7 March 2007 - Learn and Use GeoGebra Lesson 9 - Auxiliary Objects, Format Paint, Polar Coordinate Graph (see Geogebra Starters) Try the result first! Files for lesson: ggb1 ggb2 Script-o-matic for mathcast (pdf file) NEW! Mathcast with explanation coming soon...
