Constructing Tangrams
Sixth graders are introduced to how geometry and algebra are related. In groups, they graph various points on a coordinate plane and write the ordered pair for each quadrant. Using this information, they create their own tangrams to...
Curated OER
Give It a Whirl
Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.
Curated OER
Hurricane Tracking
Students access the Internet to find information on current hurricanes. They get locations, speeds, and air pressures and then plot the location of the hurricane on a hurricane-tracking map. They also access the FEMA website to solve...
Curated OER
Between The Extremes
Students analyze graphs for specific properties. In this algebra lesson, students solve equations and graph using the TI calculator. They find the different changes that occur in each graph,including maximum and minimum.
Curated OER
Investing
Students collect data on investments and draw conclusions. In this algebra lesson, students analyze exponential graphs as they relate to money. They discuss the cause of an account balance being high or low.
Curated OER
Move It
Studens collect and graph data. In this algebra activity, students use a CBL and CBR with a TI Calcualtor to observe linear graphs. They use the correct vocabualry as they discuss the collected data.
Curated OER
Know the System
Learners identify the different systems of equations. In this algebra lesson plan, students solve systems of equations using graphing, elimination and substitution. They use the Ti to graph their systems.
Curated OER
The Absolute Truth
Learners solve problems of inequalities and equations. In this algebra lesson, students add, subtract, multiply and divide to solve inequalities. They graph their solutions on a number line.
