Off You Go is a PK-12 mathematical routine that leverages children's home resources and assets to help students take a concept with which they have initial or informal understanding and explore and test its boundaries to support defining or estimating with precision. The authors provide a guide for how to adapt this routine to engage students at…

This paper presents two mathematics activities that model functions studied using the Calculator Based Ranger (CBR) software for TI-82 and TI-83 graphing calculators. The activities concern a bouncing ball experiment and modeling a decaying exponential function. (ASK)

Describes possible uses of spirographs in mathematics classrooms to study parametric equations and symmetry. (ASK)

Describes a consumer-math-skills project in which students make geometric shapes using pretzel sticks and gumdrops, then start a shop to sell them. This requires counting costs, pricing items, setting up shop, using money, making change, and understanding profits. Students reflect on the experience and write lists of the math they used to create…

This document represents the next step by the National Council of Teachers of Mathematics (NCTM) in its efforts to ensure quality, indicate goals, and promote positive change in mathematics education for grades pre-K-12. Following an introduction in Chapter 1, Chapter 2 elaborates on six guiding principles for school mathematics instructional…
