There are middle school projects that gain impact through collaboration with students outside your own classroom, such as estimating the average amount of water used per person per day. This problem takes on deeper relevance when averages are compared to those of classrooms around the country and the world. Other projects, such as finding the circumference […]

Many students never really understand volume or surface area, although they can memorize the formulas and even apply them on tests. These resources have been selected with an eye to helping students enter into the concepts of volume and surface area through practical problems, hands-on experiences, and applets they can manipulate to actually see how […]

You may have heard tales of hidden math treasure out there on the World Wide Web, but how to find it for your middle school classroom? Consider this blog post a treasure map, with X marking five sites that we’d like to recommend for productive digging. At each you will find activities, lessons, or projects that […]

Possibly for students the most surprising connection to math is art. The resources below are proof of that connection through fractals, architecture, tessellations and 3-D geometric figures. Some sites are like art galleries—just for visiting, but others involve students in creating their own artistic designs. All involve significant mathematics!

Computer technology as an instructional tool for the teaching of mathematics offers unique “hands-on” environments in which abstract concepts can be explored. These environments enable active engagement by students, an experimental approach to math concepts, and an avenue to understanding abstract ideas not readily accessible through other mediums. Virtual manipulatives are the key. In animated […]

Students often answer with the formula: “Add all the numbers together and divide, etc.” with no strong idea of what “average” means. Few adults, in fact, distinguish among the measures of central tendency: mean, median, and mode, but tend to lump them into a general idea of “what’s typical” of the data. Not a bad place to […]

Is there anything more difficult to explain at 5th and 6th grade level than the rules for multiplying and dividing fractions? These resources offer support in explaining the concepts that underlie the rules. Visual, interactive models are provided where possible. You will also find opportunities for your students to practice their skills in this area […]

As teachers, we all want our students to understand those concepts underpinning addition and subtraction of fractions— the concept of equivalent fractions, in particular. These resources offer teaching ideas on both the concepts and the skills, including demonstrations of addition and subtraction as well as problems for practice. I looked hard for material that would […]

Understanding ratio and proportion, one of NCTM’s Focal Points for grade 7, presents a real challenge for all levels of middle school. Here are classroom-friendly ways to explore the topic from several angles. Each involves visuals or hands-on activities that bring students into close contact with the abstract concept of ratio. Let other teachers hear your ideas […]

Middle school students often do well on straight calculations but feel lost when faced with more complex problems. And many tests these days require critical thinking and ask for an extended response. As in all test preparation, students need practice, especially on problems requiring more than one-step computation. Here are sites that offer test items […]
