I’m pleased to find another collection of materials similar to those found on the NLVM website that is provided free of charge to teachers and learners.  This one is Welsh and appears to have an especially wide variety of resources.  I would appreciate feedback from you if you try this one on the NGfL Cymru website.

 

NGfL Cymru:  This is a comprehensive set of materials for mathematics at all grade levels.  There are ready to go PowerPoint presentations, interactive online activities, explorations, Excel spreadsheet interactive activities, etc.  The National Grid for Learning is managed for the Welsh Assembly Government and its mission is to develop its library of interactive resources for teachers and learners at all levels.

Absurd Math:  This is a series of interactive mathematical problem solving games.  Played online, the ability to proceed on missions in a strange world requires the student to use mathematical skill and knowledge.  Many pages have hidden clues and areas.  An answer sheet may be printed to record ongoing work.  If a player needs help, they may email the staff.  They try to respond within two days  Teachers and parents may email for answer keys.

AOL Research & Learn: Have you “lost” AOL’s Quizzes and games?  Some time ago they moved to this site.  The Sudoku puzzle has 10 levels of difficulty.  A right click on the mouse records, in miniature, tentative plays you wish to keep track of.  Other games include Bookworm, Letter Linker, Scrabble Blast, Test Twist and Word Zen.  Also on this site are a World Atlas, Quizzes, and Science that includes Space, Planet earth, Animals, Natural Disaster and Global Warming.

ExploreLearning Gizmos:  Here you will find a catalog of modular, interactive simulations in math and science, grades 6-12.  There is a free 30 day trial period for teachers (including their students) and home users.  Do take a serious look at this website.  It is a wonderful learning aid.  This website previously offered 5 minutes daily of free exploration of its Gizmos, so this is a change in procedures.

Coolmath.com, Spike’s Game Zone: In addition to a wonderful collection of games, there are online interactive jigsaw puzzles featuring fractals.  They are bright and colorful with abstract cuts on the pieces.  Puzzles and games include Lemonade Stand, Marbles, Simon Says, Tower of Hanoi, and many others that will provide hours of exploration.

Ms. Lindquist, Intelligent Tutor:  This is a free service for tutoring students in writing expressions for word problems.  It was written by Neil Heffeman at Carnegie Mellon University.  This program coaches students through the process of writing expressions rather than giving them answers.

Learning Connections, Investigating Number Patterns:  This is a set of lessons that explore a variety of number patterns that include “The Quest of Nine,” “Number Patterns in Number Squares,” “Number Patterns in Multiplication Squares” and “Number Patterns in Number Lines.”

Famous Problems:  Famous Problems in the History of Mathematics is a project of the Math Forum.  Included in this collection of problems is The Bridges of Konigsberg, The Value of Pi, Puzzling Primes, Famous Paradoxes, The problem of Points, A Proof of the Pythagorean Theorem, and A Proof that e is irrational.  The purpose of the site is to examine a bit of the history of mathematics and what has inspired mathematicians through the ages.
