This lesson explains what categorical and quantitative data are in the context of statistics. Includes downloadable study guide with exercises - guide also covers other topics. [6:26]
This activity provides many ideas for celebrating the 100th Day of school.
This simple task assesses whether students can interpret function notation. The four parts of the task provide a logical progression of exercises for advancing understanding of function notation and how to interpret it in terms of a given context.
The purpose of this task is to use geometric and algebraic reasoning to model a real-life scenario. In particular, students are in several places (implicitly or explicitly) to reason as to when making approximations is reasonable and when to round, when to use equalities vs. inequalities, and the choice of units to work with (e.g., mm vs. cm).
At the end of this lesson, students will be able to recognize and apply the concepts of mean, median, and mode in real-life problems.
Learners explore the concepts of rate and ratio in a variety of problem-solving situations. Worksheets contain definitions and visual representations of concepts. Link to related ratio game. Other skills include measurement, data analysis, and number sense. Acrobat Reader required.
Student groups compete to design a process that removes the most iron from fortified cereal. Students experiment with different materials using what they know about iron, magnets and forces to design the best process for removing iron from the cereal samples.
In this activity, students build numbers from zero to ten with cereal and connect the number name and numeral. Students also explore number sentences for numbers up to ten.
Solve two challenging problems that apply properties of tangents to find the perimeter of a circumscribing shape.
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Solve two challenging problems that apply the inscribed angle theorem to find an arc measure or an arc length.

At its core, the LEGO MINDSTORMS(TM) NXT product provides a programmable microprocessor. Students use the NXT processor to simulate an experiment involving thousands of uniformly random points placed within a unit square. Using the underlying geometry of the experimental model, as well as the geometric definition of the constant π (pi), students form an empirical ratio of areas to estimate a numerical value of π. Although typically used for numerical integration of irregular shapes, in this activity, students use a Monte Carlo simulation to estimate a common but rather complex analytical form the numerical value of the most famous irrational number, π.
Contains a brief explanation of how to factor polynomials.
Practice comparing mass by trying the Teeter Totter Experiment. Watch the teeter totter move up and down as you compare Marcus to each animal.
The purpose of the task is to connect properties of fractional exponents with ordering of real numbers. One can place the numbers on the number line to emphasize this.
This problem includes a percent increase in one part with a percent decrease in the remaining and asks students to find the overall percent change. The problem may be solved using proportions or by reasoning through the computations or writing a set of equations.
This task presents a real world situation that can be modeled with a linear function best suited for an instructional context.
This task is intended strictly for instructional purposes with the goal of building understandings of linear relationships within a meaningful and, hopefully, somewhat familiar context.
Adding and subtracting numbers on a number line is a neat way to see how numbers are added and subtracted using visual interpretations.
