Open up your pupils' eyes and minds on dilations. Scholars perform dilations on a trapezoid on the coordinate plane. They compare the image to the preimage and develop generalizations about dilations.

Bring about the change you want to see in the world  or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to...

Which rate is greater and by how much? Pupils continue to compare rates to solve problems in the 20th portion of a 29-part series. Rates are presented in a variety of representations either using the same representation or different...

Varve: a deposit of cyclical sediments that help scientists determine historical climates. Individuals analyze the topography of a region and then study varve datasets from the same area. Using this information, they determine the...

Class members investigate how positive and negative numbers are useful in the real world. Individuals first read a short passage and identify terms indicating positive and negative numbers. They consider situations involving positive...

Students measure an area given a yardstick. They also convert inches into a fractions of a foot and use data to create a linear graph.

Seventh graders find constellation distances and plot the stars. In this star lesson, 7th graders plot the star points for Canis Major. Students use graphing calculators to graph the constellation. Students choose another constellation...

Students calculate and find a certain location. In this geometry lesson, students examine a coordinate plane for pair of coordinates. They calculate the distance between point using the distance formula and estimation.

Fourth graders design their own letter graph, and then produce the resulting graphs after a translation, reflection, and rotation. After a review of vocabulary, 4th graders create their graphs using crayons.

Learners graph linear equations using intercepts, find y-intercept, find x-intercepts and graph linear equations that use horizontal and vertical lines.

Students create a matrix of the vertices of a triangle and produce new matrices that dilate, translate, rotate, and reflect the original triangle. After multiplying each matrix by a new scale factor, they graph the new matrix and...

Young scholars define the solution to a system of equation. In this algebra lesson, students graph two line on the TI calculator and identify the point of intersection if there is any. They find one, zero or infinitely many solution and...

Studnents examine the degree of biodiversity that exists in one's everyday environment, in order to develop an understanding of how scientists classify organisms and to explain why biodiversity is important for living things.

students emulate a real world problem and model it with mathematics working in a small group. Observe and facilitate discussion as the groups use various strategies, such as (graphs, brainstorming, tables, and dialogue.

Students solve problems using ratios and proportions. In this algebra lesson, students identify the unit rate and convert between fractions and decimals. They create graphs from their data.

Students factor and solve quadratic equations. In this algebra lesson, students identify the domain and range of the quadratic function. They graph the parabola and identify the vertex.

Second graders use latitude and longitude coordinates to pinpoint an exact location on the map. In this geography lesson, 2nd graders utilize handouts from the Maritime Museum in order to gain practice in finding locations throughout the...

Eighth graders experiment with M&M's and a cup attached to a spring to to simulate a bungee jump. They graph the results of the experiment and make predictions for continuing the experiment. They determine the "line of best fit."

Students show reflection, translation and rotation of a simple coordinate graph picture which they have created.

Ninth graders examine rates, matrices, histograms, line graphs, data analysis and data presentation in order to develop an understanding of how these concepts apply to a the effects of a specific disease.

Fifth graders conduct various measurement activities on themselves and a partner. They measure their height, weight, thumb-to-pinky span, and body temperature, recording the information in the form of an Excel spreadsheet.

Students review how to solve problems using the Distributive Property of Mathematics. They solve problems using the paper and pencil method and then use the graphing calculator to discover the property over addition while making a visual...

Students solve problems using the Fibonacci Patterns. In this geometry lesson, students trackthe growing rate of a rabbit population. They collect the data and graph their results. They make predictions based on their results.

Learners define a functions and solve problems using functions. In this algebra activity, students differentiate functions from non-functions. They differentiate between polynomials of higher degrees.
