This short video and interactive assessment activity is designed to give fourth graders an overview of rotational symmetry.
Students identify phrases in a known song and create new patterns of music.
This short video and interactive assessment activity is designed to teach second graders an overview of rounding decimal numbers.
This short video and interactive assessment activity is designed to give fifth graders an overview of rounding decimal numbers.
This short video and interactive assessment activity is designed to give fourth graders an overview of rounding decimal numbers.
Students explore orbit transfers and, specifically, Hohmann transfers. They investigate the orbits of Earth and Mars by using cardboard and string. Students learn about the planets' orbits around the sun, and about a transfer orbit from one planet to the other. After the activity, students will know exactly what is meant by a delta-v maneuver!
Students practice rounding whole numbers with this task.
This short video and interactive assessment activity is designed to teach second graders about rounding to the nearest 2 decimal places, or the hundredths place.
An exploration of the changing role of the monarchy in British politics and culture, beginning with the accession of the House of Hanover (later Windsor) in 1714. The dynasty has encountered a series of crises, in which the personal and the political have been inextricably combined: for example, George III's mental illness; the scandalous behavior of his son, George IV; Victoria's withdrawal from public life after the death of Prince Albert; the abdication of Edward VIII; and the public antagonism sparked by sympathy for Diana, Princess of Wales. In addition to readings, materials include portraits, news footage, and films.
Simple and compound machines are designed to make work easier. When we encounter a machine that does not fit this understanding, the so-called machine seems absurd. In this lesson, the cartoons of Rube Goldberg are introduced and engage the students in critical thinking about the way his inventions make a simple task even harder to complete. As the final lesson in the simple machines unit, the study of Rube Goldberg machines can help students evaluate the importance and usefulness of the many machines around them.
This art history video discussion looks at Peter Paul Rubens' "The Consequences of War", 1638-39, oil on canvas (Palatine Gallery, Palazzo Pitti, Florence).
This art history video discussion examines Peter Paul Rubens' "Arrival (or Disembarkation) of Marie de Medici at Marseilles",1621-25, oil on canvas, 394 x 295 cm (Musee du Louvre, Paris).

This problem is an exponential function example.
Students conduct an experiment to determine the relationship between the speed of a wooden toy car at the bottom of an incline and the height at which it is released. They observe how the photogate-based speedometer instrument "clocks" the average speed of an object (the train). They gather data and create graphs plotting the measured speed against start height. After the experiment, as an optional extension activity, students design brakes to moderate the speed of the cart at the bottom of the hill to within a specified speed range.
This task provides students with an opportunity to engage in Standard for Mathematical Practice 6, attending to precision. It intentionally omits some relevant information -- namely, that a typical soda can holds 12 oz of fluid, that a pound is equivalent to 16 dry ounces, and that an ounce of water weighs approximately 1.04 dry ounces (at the temperature of the human body) -- in the interest of having students discover that these are relevant quantities. The incompleteness of the problem statement makes the task more amenable to having students do work in groups.
This task uses geometry to find the perimeter of the track. Students may be surprised when their calculation does not give 400 meters but rather a smaller number.
The goal of this task is to model a familiar object, an Olympic track, using geometric shapes. Calculations of perimeters of these shapes explain the staggered start of runners in a 400 meter race.
The purpose of this task is for students to compare two fractions that arise in a context. Because the fractions are equal, students need to be able to explain how they know that.
This word problem asks students to think about fractions.
