Balance Keeper is an educational tool that helps children practice addition, subtraction, logical thinking, and basic algebra. The purpose of the game is to balance the scale by clicking and dragging weights. Complex problems consist of unknown mystery weights. Through deductive reasoning and trial and error techniques, a child can determine these unmarked weights. Balance Keeper implements fifteen skill levels that automatically adjust in difficulty. Mastering all the levels will definitely jum

Fight Bac! Food safety education: Grades K-3
This kid-friendly interactive program - targeted to children from Kindergarten through 3rd grade. Even children can learn about food safety! This important subject has been developed into a fun presentation story in two levels, depending on the age of the children you'll be visiting. Both stories feature that germy culprit of unsafe food practices - BAC. (He's the bad guy – Bacteria.) fightbac.org, the website of the Partnership for Food Safety Education (PFSE), is your resource for Fight BAC!
This lesson introduces an anthropometric measurement system developed to identify and track people in the penal system in late 19th and early 20th century. Students conduct a guided experiment and discussions while collecting anthropometric measurements, exploring the impact of experimental errors in a scientific system, and explaining their observations/findings in writing.
Science and Technology of Mental Illness
This site provides six lessons that help students understand what mental illnesses are. PET images show changes in the brain and how treatment can change activity levels and restore functioning. Case studies and other activities explore differences among illnesses, risk factors, and treatment plan goals. Students develop a brochure to inform people about mental illness.
Counting on Art
In Counting on Art, students will explore the paintings of Horace Pippin and Wayne Thiebaud and the mobiles of Alexander Calder to discover and practice math and visual art concepts.In Pippin's Story, young children (grades K–3) focus on a painting by African American artist Horace Pippin. They will learn how to "read" the clues in a painting and write a story about the work. Students will also solve counting and time problems and create their own "secret number" painting.Calder's Balancing Ac
LangSource is a searchable, annotated bibliographic database of language and culture resources. LangSource can be used by both teachers and learners at all levels in a variety of languages. Currently, the LangSource catalogue offers resources in Arabic, Chinese, German, Hausa, Hindi, Japanese, Korean, Quechua, Spanish, Tamil, and Yoruba.
Apples to Atoms
"Apples to Atoms" is a collection of activities focused on important concepts underlying nanoscience, developed for middle school science and math students. Each of the four chapters (Size and Scale, Measurement, Microscopy, and Surface Area to Volume Ratios) contains a series of linked activities, and readings which provide context for the concepts developed in the activities. Suggested assessment items are also included. The chapters are inter-related, but are designed so they may be taught in
Introduction to X-ray Diffraction
This site is intended as a brief introduction to some of the common x-ray diffraction techniques used in materials characterization. It is designed for people who are novices in this field but are interested in using the techniques in their research. Topics include x-ray generation and properties, lattice planes and Bragg's Law, powder and thin film diffraction, texture measurement and pole figures, residual stress measurements, small-angle x-ray scattering (SAXS), and x-ray crystallography.
Treats in a Basket
Students develop intuitive understandings about the probability of landing on particular board spaces when a die is rolled. They analyze the probability of multiple rolls by making outcome tables, trees, etc. Treats in a Basket is designed to encourage students to experiment with probability. It will motivate students to learn about the subject in order win the most treats. It should be played by students who are already comfortable with fractions. Students should also be familiar with calculat
Going around in circles!: around and about a geometric figure
Geometry can be an exercise arena for strengthening those logic muscles that middle school students need to flex. When we work with a geometric figure—a circle, for instance—and apply the ancient tools of compass and straightedge, geometry can become a rich ground for developing design. And a circle has size, so a unit on this topic necessarily brings in the mathematics of its measurement. Circles, then, is a geometric topic that can provide mental challenge, opportunity for artistic develop
Social Capital and the Distribution of Household Income in the United States: 1980, 1990, and 2000
Social capital is a person or group's sympathy or sense of obligation for another person or group. The objects of sympathetic feelings have social capital. Those holding sympathetic feelings for others provide social capital. Because social capital providers internalize the consequences of their choices, they trade with each other on different terms and at different levels that would occur in arm's length transactions, all other things equal. But changes in the terms and level of trade al
Red de Oportunidades: Conditional Cash Transfer Evidence from Panama
This paper estimates the impact of the conditional cash transfer program, Red de Oportunidades, on school enrollment, child labor, and preventive health services participation in Panama. The analysis relies on data from the Living Standards Measurement Survey of 2008. It uses a propensity score matching technique to identify the impact of the program in rural and indigenous areas of the country by replicating the selection criteria followed by the government to identify potential benefici
100th Day of School Activities
Resources to mark the 100th day of school with math activities. Challenge students to generate 100 different ways to represent the number 100. Students will easily generate 99 + 1 and 50 + 50, but encourage them to think out of the box. Challenge them to include examples from all of the NCTM Standards strands: number sense, numerical operations, geometry, measurement, algebra, patterns, data analysis, probability, discrete math, Create a class list to record the best entries. Some teachers write
Hundred Board Activities 1
Students learn the patterns in the hundred board by assembling puzzles. Teachers are able to assess student use of patterns in rows and columns by observing the student at work. This task is easily differentiated to accommodate the varied levels in a first grade class by changing the number of pieces and the shape of the pieces. Puzzle bags should be sequentially lettered so that students progress through harder versions of the task. Finally, students are asked to create their own puzzles for cl
Math Tours: Fractions
Students need many concrete experiences with fractions to develop a deep understanding of the three models of fractions: area, linear and set models. Teachers need to address all three models in well-designed instructional activities so that students develop a rich concept of fractions that they can use to make sense of numbers, operations, measurement and probability. The Math Tours include: activities, problem solving, games, writing to learn, templates, math-literature connections, and web li
Instructional Strategies for Mental Math
These strategies support active student participation in math lessons and allow teachers to assess the developing proficiency levels of all students in the class by walking around to monitor student responses. These strategies are especially effective during the Mental Math part of an Everyday Mathematics lesson.
Gingerbread Man Math
Gingerbread men and gingerbread houses enjoy special popularity around the holidays, but many of these gingerbread activities are timeless and complement literature titles that teachers use at the beginning of school or after the holidays. It's very easy to incorporate mathematics into a study of gingerbread men, and students will enjoy the data collection activities and games while learning math skills and deepening their understanding of important mathematical concepts.
