Students can use geometric representations of numbers as a way to explore algebraic ideas. With the help of these representations, students can think about the relations among the numbers, express them using their own words, and represent them with letters. The activities discussed here can stimulate students to try to find various ways of solving…

The study of leap year and its development offers an interesting real-world situation for students to exercise qualitative reasoning about operations on decimals. Presents an activity in which students investigate time measurement by studying a variety of calendars, past and present. (ASK)

Introduces the whole number machine and describes its use as an odometer in an addition game. Presents an activity in which students learn mathematics while they fly across the globe. (Contains 12 references.) (ASK)

Looks at the connection between soccer fields and mathematics to help students understand middle school geometry topics. Presents an activity in which students explore relationships among polygons to discover which combinations tessellate and which combinations form polyhedra. (ASK)

Middle school students consolidate their understanding of integers and rational numbers, increasing their facility with fractions, decimals, and percents and encountering proportionality. This book shows how students can explore these important ideas in such diverse activities as exchanging currency and using area models to develop algorithms for…

This book is the third in a series of family math books whose aim is to involve parents and their children in middle school mathematics. All the activities contained in this guide are based on the National Council of Teachers of Mathematics (NCTM) Standards, and most activities involve several integrated math concepts rather than isolated skills.…

Presents an activity on reading data from a table, estimation, computation, and 15 questions about the activities and their solutions. (ASK)

Presents a collection of computer programs for teaching elementary and middle school mathematics. At the primary level, programs teach students skip counting, measurement, graphs, number patterns, place value, addition, and subtraction. An action game for the upper elementary level teaches mental math, geometry, statistics, addition,…
