FUN WITH CALENDARS - CYNTHIA LANIUS
http://math.rice.edu/~lanius/Lessons/calen.html
Using a mathematical puzzle, this activity demonstrates how
to solve a simple linear equation. It's an average math trick,
but an excellent activity with which to demonstrate algebraic
applications:
Take any calendar. Tell your friend to choose 4 days that
form a square. Your friend should tell you only the sum of
the four days, and you will tell her what the four days are.
How does this puzzle work? It uses algebra!
\|/
When you have studied the puzzle, you are invited to design
your own.

This activity for grades 6-9 (pre-algebra or algebra) was
written to comply with the NCTM Standards and to support
the Texas Essential Knowledge and Skills (TEKS).

LOGICA10 - ANTONIO DIEZ
http://www.teleline.es/personal/diez10/
El cerebro es como una máquina de acuñar monedas.
Si echas en ella metal impuro, obtendrás escoria;
si echas oro, obtendrás moneda de ley.
Para resolver la mayoría de los juegos, problemas
y divertimientos de estas páginas, solo hace falta
la lógica que emana del "sentido común" y acaso
también un poquito de paciencia. Aquí se encuentran:
- Pensamiento Lateral (acertijos)
- El acertijo del día - dedicado al pensamiento lateral
- Galimatías lógicos
- Problemas de ingenio
- Desafío a la inteligencia
- Series de números y letras
- El baile de las neuronas
- ¿Mentirosos, locos, honrados?
- Entremeses para gigantes intelectuales
- Paradojas
- Matemáticas recreativas
... ¡y mucho más!
