Math (X) - PBST (X)

## Statistics: Steppin' Out

Icon:

Using this resource group, teachers can focus on the topic of statistics by having students construct box and whisker plots to analyze and compare data sets. This resource group is part of the Mathline Middle School Math Project.

## Computation and Estimation: Alphabits

Icon:

Using this resource group, students apply the concept of ratio and percents to the distribution of letters contained in a box of Alphabits cereal. This resource group is part of the Mathline Middle School Math Project.

## Probability: Remove One

Icon:

Using this resource group, teachers can focus on the topic of probability. Students develop winning game strategies based on probable outcomes of events using dice. This resource group is part of the Mathline Middle School Math Project.

## Measurement: How Many Noses Are in Your Arm?

Icon:

In this professional development video, teachers focus on the topic of measurement by having students apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm. This video can be used in conjunction with the How Many Noses Are in Your Arm? lesson plan.

## Statistics: Wet Heads

Icon:

Using this resource group, teachers can focus on the topic of statistics by having students construct stem and leaf plots based on how estimations compare with actual data. Students learn to create stem and leaf plots and back-to-back stem and leaf plots to display data collected from an investigative activity. This resource group is part of the Mathline Middle School Math Project.

## Statistics: Whirlybirds

Icon:

Using this resource group, teachers can focus on the topic of statistics by having students measure, predict, and determine the frequency of an event as it relates to how close whirlybirds land to a target. Students will learn to measure to the nearest centimeter and predict and determine the frequency of an event. This resource group is part of the Mathline Elementary School Math Project.

## Statistics: Something Fishy

Icon:

Using this resource group, teachers can focus on the topic of statistics by having students apply the concept of ratio and proportion to the capture-recapture statistical procedure. Students estimate the size of a large population by applying the concepts of ratio and proportion. This resource group is part of the Mathline Middle School Math Project.

## Probability: Rock Around the Clock

Icon:

Using this resource group, teachers can focus on the topic of probability through the application of the Monte Carlo method. Students use the Monte Carlo method to estimate a reasonable number of packs of gum that need to be purchased to win a complete set of prizes. This resource group is part of the Mathline Middle School Math Project.

## Probability: The Smithville Families

Icon:

Using this resource group, teachers can focus on the topic of probability by using a simulation involving Pascal's triangle. Students create the number sequences of Pascal's triangle and discover a relationship that this triangle has to theoretical probability. This resource group is part of the Mathline Middle School Math Project.

## 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.

## Number Sense and Computation: An Apple a Day

Icon:

Using this resource group, teachers can focus on the topic of number sense and computation by having students make estimates to analyze the number of apples per acre. Students learn to take samples and use benchmarks to make reasonable estimates. 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.

## Patterns and Relationships: The Magic Box

Icon:

Using this resource group, teachers can focus on the topic of patterns and relationships. Students learn to recognize, describe, create and extend repeating and arithmetic patterns. This resource group is part of the Mathline Elementary School Math Project.

## 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.
