Learning Projects in Mathematics:
MathMol
Grades 6 - 8
This site is a starting place for molecular modeling.
Rather dry and "textbooky", but it covers some
interesting material. Includes quizzes and models.'
No Matter What Shape Your
Fractions Are In
3rd-6th grade
Uses cut out shapes to explore fractions and area
Drawing Fun Fractions More Fun Fractions
4th-6th grade
Using shapes from Pattern Blocks, you are asked
surprisingly sophisticated questions about fractions. If
you can figure these out, you understand fractions.
(should carry over to percentages too, I think.)
Brain Teasers
4th to 8th grade
Fun, but challenging--or should that be challenging but
fun?--math puzzles for different age levels. The archives
are the richest source of puzzles. These puzzles do not
involve major levels of computation; you use logic to
figure them out.
Word Problems for Kids
The "kids" go up to 12th grade and higher
algebra. These are not "word problems" in the
traditional sense; they are more puzzles or brain
teasers, and some are quite hard.
Clever Games for Clever
People
5th grade up
Tricky pencil and paper games, mostly based on being (or
not being) the last player to pick up a peanut, connect a
dot, etc.
Geometry Problem of the
Week
A different, non-routine geometry problem every week;
again with a solution given the past week. These problems
are challenging for kids (and some adults).
Escape from Knab
Highly clever salary and budget simulation that contains
enough real-world information to make it truly useful.
Playing this game may help your kids understand "We
can't afford it" even though, to a kid, you
obviously have "lots of money" in your
wallet--and insurance, utility bills, interest, taxes,
etc. The game deals with salary and expenses, including
the less-tangible ones, as well as credit cards, interest
(in and out), living expenses and writing out checks.
Cash Register
Easy but clever simulation of the change you
should get back from purchases of various sizes. It has
pictures of real coins, but could use a little
"story" or game to make it more fun. US money,
of course.
Easier Fibonacci Number Puzzles
Fibonacci numbers—starts fairly easy—and simple—and gets more
complicated as you go along. The first part is a good explanation
of Fibonacci numbers, but only math lovers are apt to want to go
through the whole site.
Pattern Blocks: Exploring Fractions with Shapes
This program lets kids use the traditional six shapes of pattern
blocks—triangle, hexagon, rhombus, another rhombus, trapazoid and
square to form patterns and pictures on a grid. Pieces can be
rotated to form more elaborate pictures. The pieces are also used
to form fraction questions.
