Pupils practice multiplying and dividing whole numbers by fractions. They study the multiplicative identity property that states that the product of any number and 1 is that number. They multiply whole numbers by fractions close to 1 and...

Learners explore how GPS works, the mathematics behind the technology, and how GPS is used. They find positions in one and two dimensions, and participate in a WebQuest that explores how math is used to find a location on Earth using GPS.

Discover how to analyze architecture from a geometric standpoint. The fourth installment of an 11-part unit on architecture first provides a presentation on axis, balance, basic form, formal, pattern, proportion, symmetry, and tripartite...

Most young mathematicians are aware that the planets don’t orbit the sun in a circle but rather as an ellipse, but have never studied this interesting feature. This resource looks at the planetary orbits in more detail and helps learners...

Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...

Kindergartners are introduced to basic shapes. Learners spend 45 minutes a day in geometry centers carrying out the activities outlined in this ambitious plan. There are games, hands-on activities, interactive websites, art projects,...

Kindergarteners explore various representations and uses of numbers to develop number sense. They participate in an activity and arrange patterns into groups. Students compare the sets and describe the objects in each set.

Students represent and solve problems using geometric models and apply geometric properties and relationships. They also practice constructing and measuring angles. By constructing, drawing, visualizing, and comparing geometric figures...

Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...

Students use diagrams or lists to show relationships. They also identify the pattern of triangular numbers. The mathematics behind situations provide a way of problem solving to examine the answers.

Students explore geometric shapes.  In this kindergarten geometry lesson, students create a fall quilt consisting of three different paper geometric quilt squares that when assembled form a scarecrow, a pumpkin, and a crow. ...

Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.

Students identify a tangram. In this geometry lesson, students read Grandfather Tang's Story and retell each story using the tangrams on a flannel board. Students use tangrams to complete an included worksheet.

Young scholars build sled kites. in this kite building lesson, students must read directions for kite building and enlarge the proportions of the given kite pattern. Young scholars focus on the angles and line of symmetry in their...

Learners define choropleth map. They construct a choropleth map. They interpret a choropleth map. They present geographic information.

High schoolers investigate linear equations as they use technology (Cabri, Jr.) to explore the equations of lines in slope-intercept form. The technology allows learners to manipulate the line and observe the changes in the parameters of...

Students find coordinate points on a grid and create a line graph with those points. This lesson should ideally be used during a unit on various types of graphs. They make and use coordinate systems to specify locations and to describe...

Second graders use symmetry to create their own small quilt squares. They attach all of the squares to create a large class quilt.

First graders explore eight geometry activities that improve understanding of positional words and shapes. They identify, describe, and create simple geometric figures. They help another student who may not understand the concept yet.

Students create handcrafted paper Hawaiian quilt squares. They do this to show the concept of symmetry across two lines of reflection.

Students create tessellations with computer software while applying their knowledge of reflections, rotations, and translations.

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson gives students a meaningful way to practice these...

Sixth graders graph translations (slides) and reflections (flips) on a coordinate plane. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders write a paragraph telling...

Fifth graders practice solving problems.  In this fraction and decimal lesson, 5th graders recognize the relationship between fraction and decimals.  Students estimate problem results and write expressions to use for problem...
