It's the stairway to learning! Scholars research all aspects of building a staircase. Using information from building codes, they write and graph a system of inequalities to analyze the constraints. The completed project is a scale model...

While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this lesson. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is by viewing a...

Students explore probability by using games based on probable outcomes of events. They name all of the possible outcomes of an event and express the likelihood of such an event occurring.

Discover the connection between vectors and translations. Through the instructional activity, learners see the strong relationship between vectors, matrices, and translations. Their inquiries begin in the two-dimensional plane and then...

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

Test young mathematicians' knowledge with an assessment aligned to California's fifth grade state standards. The exam covers a multitude of concepts including fractions and decimals, positive and negative numbers, measurement; and...

Presenting ... the gold standard for a lesson. Learners first investigate a task maximizing the area of a plot for gold prospecting. They then examine a set of sample student responses to evaluate their strengths and weaknesses.

There are many different options for graphing data, which can be overwhelming even for experienced mathematcians. This time, the focus is on histograms and Venn diagrams that highlight the frequency of a range of data and overlap of...

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Second graders explore how musical instruments h ave varying geometric shape, and how those geometric shapes correspond to three-dimenaional shapes that students have studied.

In this congruent figures worksheet, students analyze a geometric shape and choose from the answer box any figures that are congruent to that shape. There are 3 problems.

Students create a glossary of geometric terms while exploring tangram manipulatives.

Students recognize that quilts are created by geometric components. They examine how quilts are an artistic art form that show the cultural heritage of the people who make them.

Sixth graders determine the perimeter of geometric shapes with a grid at technology based resource. While looking at figures on an overhead, they determine how much border they would need to go around a figure. They also complete...

Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...

Fourth graders investigate congruent shapes. In this congruency lesson, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.

In this side lengths worksheet, students determine the value of x in 4 pairs of shapes. A reference web site is given for additional activities.

Students cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...

Students explore geometric concepts by working with Tangram Puzzles. In this Tangram challenge activity, students use problem-solving tasks that involve physical manipulatives. Students select a picture and use all seven pieces...

In this math worksheet, students examine 4 pictures of 3D objects and write the name of each. Students then study 3 pictures and figure the number of faces, edges and vertices on each.

Fourth graders, using a straight edge, determine whether a point is inside or outside of a given figure. With worksheets, 4th graders practice analyzing geometric relationships such as parallel to, perpendicular to, etc.

Students create a scrapbook. In this geometry lesson, students use digital cameras to take pictures of geometrical concepts. Students use the pictures to create a "Geotown" scrapbook.

Students explore geometric vocabulary through creation of shapes on a geoboard. They present design attributes, transfer of design, and color-coding components mix to create a fun and exciting lesson plan that stretches student thinking.
