Iterating the Function over Real Numbers
Students use a spreadsheet to find sequences of numbers. In this algebra lesson, students find the values for c of a quadratic written in standard form. They relate the behavior of the graph to the values of the equation.
Curated OER
Moving Straight Ahead
Students analyze the relationship between speed, time and distance. In this math lesson, students plan a school trip. Students determine the efficiency and cost effectiveness of a trip.

How Sharp Is Your Memory?
Students play a memory game as they explore reasoning. For this algebra lesson, students identify concepts using pictures and words. They model real life scenarios using hands on manipulatives.
Curated OER
Sun and Temperatures
Students consider the relationship of temperature to environmental conditions and then apply their knowledge to a practical event. The task assesses students' knowledge and application of that knowledge to an additional situation.
Curated OER
Move It
Studens collect and graph data. For this algebra lesson, 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
Functions in Motion
Students graph polynomials functions and analyze the end behavior. In this algebra lesson, student differentiate between the different polynomials based on the exponents. They use a TI to help with the graphing.

Survey Project
Eighth graders create a website using FrontPage. They use inserted forms to collect survey information and use Microsoft Excel and MS Word to create a presentation of the survey and the results.
Curated OER
Exploring Exponents
Students solve problems dealing with exponents. In this algebra lesson, students solve problems using interactive online problems. They create visuals and gain a better understanding of the concepts.
Curated OER
Investigating Nets and Polyhedra
Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

No Edge, No Center -- Exploring the Shape of Our Universe
Students examine various "spaces" (including ones that are one-dimensional, two-dimensional, and three-dimensional). For each space, they will examine what it means to have or not have an edge, or to be finite or infinite.
Curated OER
Calendar and Opening
Students review the days of the week and tell what the current day is by singing a song. They fill in the sentence telling the day of the week it is and then discuss what day yesterday was and the name of the day tomorrow and then talk...
