- NEW for 2000
- Let's Graph
Students make bar graphs online after setting up and solving a simple system of equations.

- Who Wants Pizza?
A series of activities building the concept of fractions. The activities contain a self-check activity that is graded on-line.

- Let's Count
Another series of activities for counting, recognizing patterns, introducing subtraction and addition. Includes a Spanish version -- Vamos a contar.

- Visualizing an Infinite Series
From counting to infinity? This may not be as big a jump as it at first seems. It's fractions and adding all rolled into one.

- Java-enhanced Power Cards
I've added a Java applet to this mathemagic trick.

- Hidden Irrationals
What's the rule? Students will find line segments that they can and cannot draw of various irrational lengths, and then find the rule that allows them to draw or not draw. The page should be printed and the segments shaded in.

- Encouraging Mathematical Thinking
Come join us in our conversation about the use of discourse as the basis for encouraging students' mathematical thinking in classrooms and for supporting professional growth. A collaboration of teacher practitioners and Math Forum staff, this videopaer reflects an attempt to integrate practice and research, reporting on findings culled from discussions of research articles and chapters, classroom practice, and videotapes of classroom teaching.

- Oldies but goodies
