In this video segment from TV411, figure skaters compute their average daily practice time.
Material Type: Lecture
The purpose of this task is to provide students with a concrete situation they can model by dividing a whole number by a unit fraction.
Material Type: Activity/Lab
This Cyberchase video segment features Bianca, who must figure out the fastest route to a movie premiere.
Material Type: Lecture
In this card game students play in pairs to practice recognizing the biggest number.
Material Type: Activity/Lab
The purpose of this game is to help students think flexibly about numbers and operations and to record multiple operations using proper notation.
Material Type: Activity/Lab
Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package things. Students then consider why consumer goods generally aren't packaged in cube-shaped boxes, even though they would require less material to produce and ultimately, less waste to discard. To display their findings, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved. The activities involved provide valuable experience in problem solving with spatial-visual relationships.

Build fractions from shapes and numbers to earn stars in this fractions game or explore in the Fractions Lab. Challenge yourself on any level you like. Try to collect lots of stars!
Material Type: Simulation
Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)
Material Type: Lecture
This lesson focuses on calculating the areas of rectangles. It is designed to enable adult students to successfully master basic geometry knowledge in order to achieve their High School Equivalency (HSE). Areas to be covered include types of polygons, quadrilaterals, rectangles; calculating areas of rectangle and calculating costs. Students will apply this knowledge to practical areas of their lives such as calculating the costs of purchasing carpets or painting of walls
Material Type: Interactive, Lesson Plan
In this task, students can see that if the price level increases and peopleŐs incomes do not increase, they arenŐt able to purchase as many goods and services; in other words, their purchasing power decreases.
Material Type: Activity/Lab
This task suggests methods of introducing and continuing choral counting in the classroom.
Material Type: Activity/Lab
