What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

Scale up your lessons with a performance task. Young data analysts work through an assessment task on scaled bar graphs. They answer questions about a given scaled bar graph on favorite colors, analyze a bar graph to see if it matches...

First graders, exploring lines of symmetry, follow directions to create a symmetrical snowflake from their own homemade icing. As a class, they discuss lines of symmetry and determine if specific shapes are symmetrical. After the...

Young learners listen to the story book The Greedy Triangle as the teacher introduces new polygon shapes. They use geometric stencils to trace a quadrilateral, a pentagon, a hexagon, and an octogon onto a foldable notepad....

Students find the mass of the top quark. In this physics activity, students create a vector diagram from a given set of data. They discuss their calculations and findings in class.

Eighth graders use a stencil to make a figure with which they discover the horizontal line of reflection, the vertical line of reflection, and the diagaonal line of reflection using coordinates.

Eighth graders solve problems involving percentage increases and decreases. Using given percentages, 8th graders transform a square into a rectangle. They apply the area formulas for squares and rectangles.Students observe the percent...

In this reflection, translation and rotation instructional activity, students determine which of these things have been done to s set of figures. A reference web site is given for additional activities.

In this reflection, rotation and translation activity, students determine which has been done to a set of 6 figures. A reference web site is given for additional activities.

Students use Geometers SketchPad to find the area and perimeter of several shapes. In this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

Students watch videos about various modes of transportation, they examine the energy transformations that occur in each, and they be introduced to the laws of thermodynamics.

Students use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Students describe, make and compare polygons. For this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.

Students explore the need for good farm land and reasons for the disappearance of agricultural areas. They brainstorm environmental friendly decisions and soil conservation. In their community, students explore new land developments...

Pupils explore the concept of geometric symmetry. In this geometric symmetry lesson, students walk around their school and take pictures of objects that demonstrate symmetry. Pupils use Microsoft Paint to draw the lines of symmetry on...

Students observe how certain geometric shapes can be used to make some structures rigid and others flexible. The activity involves construction of a 30-60 right triangle, folding while following directions, and identifying polygons.

Students become familiar with drawing segments and points. They understand how perspective drawing differs from three dimensional sketching. They demonstrate three dimensional and perspective drawing.

High schoolers investigate linear, quadratic and exponential equations using the TI calculator. They identify relation and functions using ordered pairs, graph the data, analyze the data, and relate it to real-world situations.

Students analyze and classify sets of pictures using a mathematical classification system and create original works of Art Deco tiles using this new knowledge and four types of symmetry.

Students establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

If both pairs of opposite sides of a quadrilateral are congruent, is the quadrilateral a parallelogram? This task asks learners to determine the answer and to support their answer with a proof. The resource includes a commentary for...

Students experiment with converting fuels to energy. They also must identify different types of fuels and ways to conserve energy.

Students practice saying their numbers and identifying the words. They use whole numbers and decimals to practice grouping numbers into different categories. They write the word of the number they are shown.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...
