Students apply several methods developed to identify and interpret patterns to the identification of fingerprints. They look at their classmates' fingerprints, snowflakes, and "spectral fingerprints" of elements. They learn to identify each image as unique, yet part of a group containing recognizable similarities.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

In this video segment from Cyberchase, the CyberSquad learns how to read a thermometer as they try to keep their chocolate sculpture from melting.

In this video segment from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.

In this video segment from Cyberchase, the CyberSquad must get into a vault before Hacker, Buzz and Delete by cracking a code of shapes and numbers.

This webpage contains customizable resources that promote evidence-based practices, such as Universal Design for Learning (UDL), and that make use of technology to support the Common Core State Standards (CCSS) for all learners. Resources include Math Instructional Strategy Guides that address effective practices as well as sample lessons and articles that provide strategies for implementing formative assessment, UDL, and technology.

This virtual manipulative helps students explore ideas related to multiples of numbers, patterns of multiples, and common multiples. The manipulative displays a grid containing numbers from 2 to 200 and the user can manipulate the grid to display multiples, remove multiples, or identify common multiples. Instructions for using the applet and activities are included.

The CyberSquad communicates using a secret code in this video segment from Cyberchase.

Explore perimeter through rectangular and straight-line arrangements of tables, calculating the number of chairs needed to surround different arrangements. Tables and Chairs is one of the Interactivate assessment explorers.

In this formative assessment lesson students identify patterns (both linear and exponential) in a realistic context. They may solve this problem through a variety of strategies, providing opportunities for groups of students to share and critique various problem solving approaches.

In this video from Cyberchase, the CyberSquad must figure out the new input/output pattern on HackerŒë_í_Œ_ larger cyberfrog.

In this activity, learners decipher a page from the Dresden Codex, one of the few Mayan books still in existence. By thinking like an archaeologist, students combine their mathematical abilities with some basic logic and trial-and-error investigation to figure out what the codex means. In the course of this explorations, participants discover: How archaeologists have figured out what Mayan documents mean. How the Mayan system of counting is like ours, and how it is different. How Mayan beliefs were tied to their understanding of mathematics.

The CyberSquad figures out how to represent the patterns of music played by four instruments in this Cyberchase video segment. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

In this Cyberchase interactive, select the color, number, and shape of the next term in the pattern.

Students explore different repeating patterns to predict when two or more events will occur at the same time. They are encouraged to create patterns and draw conclusions.

Hacker and the CyberSquad use two different staircases as they race to reach the Good Vibration in this video segment from Cyberchase. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

Students learn about biomedical engineering while designing, building and testing prototype surgical tools to treat cancer. Students also learn that if cancer cells are not removed quickly enough during testing, a cancerous tumor may grow exponentially and become more challenging to eliminate. Students practice iterative design as they improve their surgical tools during the activity.

This problem, from the collection of Aunty Mathilda challenges, promotes algebraic thinking and problem solving strategies. When Mathilda was ten years old her rich aunties wanted to give her a gift of money for her birthday but she must first decide if she would rather have one more silver dollar then she received last year on her birthday or twice as many dimes then she received last year. Aunty Mathilda's nephew believes she made the wrong decision. Included are links to an easier challenge and to a harder one, and additional background support: alignment to the CCSS standards, explanations, literature connections and extensions regarding the challenge.

Color numbers in Pascal's Triangle by rolling a number and then clicking on all entries that are multiples of the number rolled, thereby practicing multiplication tables, investigating number patterns, and investigating fractal patterns. Coloring Multiples in Pascal's Triangle is one of the Interactivate assessment explorers.
