We are currently developing the online version of our math curriculum. Here is a sample lesson: Finding the area of a circle A circle is a collection of points a certain distance (its radius) from another point, its center. The area of the circle is all of the space inside of it. To find the area: Take the radius (r) of a circle (the distance from the circle’s center to any point on the circle itself) Square it Multiply by π (the Greek letter pi, pronounced “pie,” is an irrational number that’s a bit more than 3: round pi to… Learn more

## Lesson: Negative and Positive Numbers (Introduction)

Physical Oceanographer Emmanuel Boss enjoys spending time at sea level (elevation 0) and his work takes him into the ocean. : To understand how he does that, we need to understand: Integers in Real-World Contexts — 5 and + 5 look similar, but they are very different numbers. They are opposites and the difference between them is 10! +5 is the number 5 you have worked with since learning to count. It’s 5 units above zero (0). Negative five (- 5) is five units below zero. Positive and negative numbers can tell you how much money you have or you owe…. Learn more

## Orienting Students for Math

John Troutman McCrann, a high school math teacher, NBCT, and MfA Master Teacher Fellow in New York City, writes a column for Education Week about “his quest to integrate inquiry- and performance-based learning into his instruction, and how these concepts might inform education policy.” He is also a curriculum developer for Math4Science’s Explore Math curriculum and math and science teacher at Harvest Collegiate, one of M4S@School’s partner schools. His latest column is entitled “Orienting Students for Math” and he discusses leading a group of teachers in a two day mathematical orientation for new 9th grade students. One of their objectives was to… Learn more

## Evolutionary Genetics

When you think of evolution, perhaps you imagine a very long tree of life, extending across millions of years, starting with one-celled creatures and ending with us: human beings (Homo sapiens). But evolution also happens more quickly. The development of antibiotic-resistant species of bacteria is also evolution in action: some of the tiny creatures that cause illnesses in human beings no longer respond to medicine that once cure those illnesses. This challenges doctors and scientists to come up with new ways of protecting people. Evolutionary geneticists like Elizabeth Alter examine DNA and other genetic evidence to help us understand how… Learn more

## Nuclear Physicist

Most of the mass — most of the “stuff” — in the visible universe is made of tiny particles called quarks and gluons. We don’t yet fully understand these particles, found in the nucleus of an atom. Nuclear physicists explore their properties, which give us clues about the history of the universe and the Big Bang and also the movement and interactions of everything around us. Nuclear Physicist Renee Fatemi studies the spin of protons and the particles within them. Her work helps us understand the properties of ordinary matter and the fundamental particles within it.
