One of my favorite sites to share with math teachers is the National Library of Virtual Manipulatives. This site breaks math concepts down by topic: Numbers and Operations, Algebra, Geometry, Measurement and Data Analysis & Probability. For each of these, there are resources to match different grade levels from PK-2 to 9-12. For a classroom with an interactive white board- or even a wireless mouse, students can manipulate various mathematical interactive pieces.
These are some Probability interactives that caught my eye.
- Savings Calculator – Explore how savings, with or without regular deposits, grow over time.
- Hamlet Happens – Verify that rare events happen by drawing letters from a box.
- Stick or Switch – Investigate probabilities of sticking with a decision, or switching.
- Whammy Awards – See how using different voting schemes can result in contradictory outcomes.
