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.

Agent Obfusco's Challenges | Odd Squad

Icon:

Olive and Otto have to solve a series of challenges to keep their Odd Squad badges. Olive and Otto become concerned when they find out that the test they have to take to keep their Odd Squad badges is being administered by Agent Obfusco, a mysterious agent who speaks only in word problems. They create number sentences to figure out the answers.

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.

Statistics: Creatures Features

Icon:

Using this resource group, teachers can focus on the topic of statistics. Students research and classify animals of the temperate forest; make a circle graph; collect, display (using a bar graph or line plot), interpret, and analyze a set of data. This resource group is part of the Mathline Elementary School Math Project.

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.

Probability: Chances Are (Part 3)

Icon:

In this professional development video, teachers focus on the topic of probability by identifying the likelihood of an event based on a set of data relating to mystery spinners. This video can be used in conjunction with the Chances Are (Part 3) lesson plan, as well as the Chances Are parts 1 and 2 videos and lesson plans.

Probability: Chances Are (Part 1)

Icon:

Using this resource group, teachers can focus on the topic of probability by having students identify the likelihood of an event using a walk-on probability scale. Students learn to describe events that are certain, impossible, likely, and unlikely to occur. This resource group is part of the Mathline Elementary School Math Project.

Measurement: It Takes Ten

Icon:

In this professional development video, teachers focus on the topic of measurement by having students estimate and measure in a variety of lab experiments. This video can be used in conjunction with the It Takes Ten lesson plan.

Measurement: Bubble Mania
