## Geometry (2004)

Icon:

Make sense of math! Using number sense, algorithms and hands-on manipulative, kids tackle math problems found in real-life situation. Whether splitting a pizza evenly, estimating the cost of a new toy or graphing the results of a science project, math is encountered in many forms.

## Shapes in Transportation

Icon:

Two children explore the different shapes they see during a road trip to the city. Defines geometric terms such as angle, cylinder, dimension, line segment, parallel, prism, and rhombus.

## Geometry and Spatial Relations: It's a Perfect Fit (Part 2)

Icon:

In this resource group, teachers can focus on the topic of geometry and spatial relations by having students identify and describe numerical relationships found among pattern block shapes. Students learn to join pattern block pieces together to cover a region. This resource group is part of the Mathline Elementary School Math Project.

## Geometry and Spatial Relations: It's a Perfect Fit (Part 1)

Icon:

Using this resource group, teachers can focus on the topic of geometry and spatial relations and, in particular, on identifying, describing, and classifying two-dimensional shapes. Students are challenged to duplicate two-dimensional shapes and sort a collection of shapes according to their attributes. This resource group is part of the Mathline Elementary School Math Project.

## Number Sense and Computation: To Half or Half Not

Icon:

In this professional development video, teachers can focus on the topic of number sense and computation by creating equivalent fractions that represent one-half through the use of geoblocks. This video can be used in conjunction with the To Half or Half Not Lesson Plan.

## Geometry and Spatial Relations: It's a Perfect Fit (Part 3)

Icon:

In this professional development video, teachers focus on the topic of geometry and spatial relations by combining geoblocks to make three-dimensional shapes. This video can be used in conjunction with the "It's a Perfect Fit (Part 3)" lesson plan, as well as the "It's a Perfect Fit (Part 1 and Part 2)" videos and lesson plans.

## Geometry: Tiling the Plaza

Icon:

In this professional development video, teachers focus on the topic of geometry by having students arrange pattern blocks to create tessellations and explore geometric patterns. This video can be used in conjunction with the Tiling the Plaza lesson plan.
