The Vermont Portfolio Program invites students to use creative strategies to solve story questions. Students choose a problem to solve and send in a solution showing how they found it; assessments of their efforts are returned via e-mail.
Questions are provided to help guide students toward finding a strong solution, along with suggestions for problem-solving and communication skills, and solution strategies.
Suzanne Alejandre's new Web unit introduces students to the surface area of polyhedra, focusing on the importance of measurement. She supplies numerous nets in the form of handouts to be cut out and folded in the classroom.
Students calculate the surface area of a rectangular prism; name the characteristics (number of edges, faces, vertices, and the shape of the face) of six specific polyhedra (cube, tetrahedron, octahedron, dodecahedron, icosahedron, and cuboctahedron); demonstrate their understanding of these characteristics; and explore polyhedra in the real world through crystalline structures and 'buckyballs'.
Writing samples and suggestions for student activities are provided, and all objectives are coordinated with the NCTM Standards.
Numeracy can be defined as "...the aggregate of skills, knowledge, beliefs, dispositions, and habits of mind - as well as the general communicative and problem-solving skills - that people need in order to effectively handle real-world situations or interpretative tasks with embedded mathematical or quantifiable elements."

The 1996 Puzzle featured in our last newsletter filled up so fast we thought we'd offer another similar test of your ingenuity. Here's the challenge: using four 4's and any operations, try to write equations that have the numbers from 0 to 100 as the answer.
As this is the first announcement of our Four 4's Puzzle, if you act quickly you should find plenty of open slots. Please send answers using the e-mail link on the Web page.
