Premade number tents to use clothesline math with linear, exponential and trignometric functions.

Premade number tents to use clothesline math with angle relationships such as vertical, complementary, supplementary and the angles created with parallel lines and a transversal. Premade number tents for recognizing relationships within triangles and polygons.

Want to know how to set up clothesline math in your classroom? Read this post and find a few different methods. Then, choose which one works best for your classroom culture.

Open Middle provides math problems that have a closed beginning, a closed end, and an open middle. This means that there are multiple ways to approach and ultimately solve the problems. Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding.

This Illustrative Mathematics task has students further their understanding of the algebra of the complex numbers.

This Illustrative Mathematics task is intended as an introduction to the algebra of the complex numbers, and also builds student's comfort and intuition with these numbers.

This Illustrative Mathematics task serves as a possible first student exploration after an initial introduction to the form and arithmetic of complex multiplication.

No one wants to spend more money than necessary on heating and air conditioning. But, everyone wants to be comfortable and cozy while at home. The development of programmable thermostats was an initial effort to assist in reducing energy costs. With a programmable thermostat, you can manually preset a schedule of temperature increases and decreases for weekdays and weekends, and day and night periods, to keep your home cool or warm when needed, but save energy when not needed. Any adjustment to the schedule requires a manual change at each thermostat.

A regional city has had lots of problems with gangs and violence over the years. The mayor, chief of police, and city council need your help. Data are available for the following: Incidents of violence, Homicides, Assaults, Regional Population (Census data), Unemployment, Unemployment rate, High School enrollment, High school drop outs, Graduation rate, Drop out rate, Prison population, Released on parole, Parole violations, Percent of parole violations, and Juvenile Inmates. Analyze and model these data to give the city a plan to reduce violence. After you complete your analysis and model, prepare a news release for the mayor briefly outlining your proposals that recommend a campaign strategy to curb the violence.

Taraxacum officinale, commonly referred to as the dandelion, is a plant native to Eurasia that can now be found worldwide[1]. This plant is easily identifiable by its bright yellow flowers (Figure 1) and its distinctive “puffball” seed head (Figure 2). Each seed from this head is attached to a parachute-like structure, known as a 'pappus', which facilitates wind dispersal[2]

TuvaLabs Data Stories provide resources for teachers to engage students in rich discourse about an interesting topic and then allows students to come to conclusions using mathematical reasoning and tools.

The design of airline terminals varies widely. The sketches below show airline terminals from several cities. The designs are quite dissimilar. Some involve circular arcs; others are rectangular; some are quite irregular. Which is optimal for operations? Develop a mathematical model for airport design and operation. Use your model to argue for the optimality of your specified design. Explain how it would operate.

Intel® developed its Shooting Starâ„¢ drone and is using clusters of these drones for aerial light shows. In 2016, a cluster of 500 drones, controlled by a single laptop and one pilot, performed a beautifully choreographed light show

It is almost election time and it is time to revisit the electoral vote process. The constitution and its amendments have provided a subjective method for awarding electoral votes to states. Additionally, a state popular vote, no matter how close, awards all electoral votes to the winner of that plurality. Create a mathematical model that is different than the current electoral system.

The Emergency Service Coordinator (ESC) for a county is interested in locating the county’s three ambulances to best maximize the number of residents that can be reached within 8 minutes of an emergency call. The county is divided into 6 zones and the average time required to travel from one zone to the next under semi-perfect conditions is summarized in the following Table 1.
