This comprehensive study guide highlights the main terms and formulas needed to review number lines. Examples are included.
A free CK-12 account is required to view all materials.
Graph and solve systems of linear inequalities.
A free CK-12 account is required to view all materials.
Students explore the graph of a rational function given by its formula. The tutorial examines vertical and horizontal asymptotes. The activity consists of examples with solutions.
This final lesson in the unit culminates with the Go Public phase of the legacy cycle. In the associated activities, students use linear models to depict Hooke's law as well as Ohm's law. To conclude the lesson, students apply they have learned throughout the unit to answer the grand challenge question in a writing assignment.
Find the area and perimeter of quadrilaterals using their coordinates. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
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.
In this simulation of a doctor's office, students play the roles of physician, nurse, patients, and time-keeper, with the objective to improve the patient waiting time. They collect and graph data as part of their analysis. This serves as a hands-on example of using engineering principles and engineering design approaches (such as models and simulations) to research, analyze, test and improve processes.
A tutorial on how to graph a linear inequality in two variables. The tutorial offers step-by-step instruction and examples of how to graph linear inequalities.
Students practice graphing ordered pairs on IXL math and on a worksheet to create a picture.
Students continue to build their graphing skills. They experience a real world application of graphing by organizing survey results.
Students read and create graphs based on Olympic data for 2014.
Students use their timed test scores to create a bar graph that compares their progress in learning math facts.
Students review how to make bar graphs, line plots, and pictographs by tallying the contents of snack mix and building graphs to show their data.
Multiple graphs can represent the same data set and make the information easier to understand.
Students can use graphs to carry the theme of kindness into their worlds.
Using decimals and finding perimeter and area all while learning about the metric system.
A lesson for students to work with writing and graphing inequalities. Documents to execute the lesson are included.
Interactive matching game where linear and quadratic expressions are matched to their associated functions graphs. Site features over 100 graphs, although only six are used at one time.
Students use ultrasonic sensors and LEGO© MINDSTORMS© NXT robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold values in order to improve the robot's performance (iterative design). Students see how problem solving with biomimicry design is directly related to understanding and making observations of nature.
Student pairs are given 10 minutes to create the biggest box possible using one piece of construction paper. Teams use only scissors and tape to each construct a box and determine how much puffed rice it can hold. Then, to meet the challenge, they improve their designs to create bigger boxes. They plot the class data, comparing measured to calculated volumes for each box, seeing the mathematical relationship. They discuss how the concepts of volume and design iteration are important for engineers. Making 3-D shapes also supports the development of spatial visualization skills. This activity and its associated lesson and activity all employ volume and geometry to cultivate seeing patterns and understanding scale models, practices used in engineering design to analyze the effectiveness of proposed design solutions.
Students will collect data from a Play Lab project and visualize it using different graphs in this exploratory lesson. This lesson aligns to national Computer Science standards from CSTA.
