This article provides a brief discussion of the importance of teaching students to analyze data and representations of data as well as two resources that can help teachers implement these strategies into their instruction.

This classroom activity, which centers on documenting the location of a meteorite in Antarctica, introduces students to the technology of Global Positioning Systems. The printable handout includes a series of inquiry-based questions to get students thinking about the challenges of marking exact positions in an area where the landscape is continually changing, illustrated activity directions and a worksheet that guides students through the way satellites are used in GPS and includes areas for recording their findings.

This lesson unit is intended to help you assess how well students are able to: Calculate the mean, median, mode, and range from a frequency chart; and to use a frequency chart to describe a possible data set, given information on the mean, median, mode, and range.

This lesson explores several strands of the musical "DNA" that make up the beat of popular music. Looking to the past, this lesson asks what it means to call music "Afro-Cuban" "Afro-Caribbean," or more broadly, "African-American." Students will use Soundbreakingclips of Santana and Beyonce and the Soundbreaking Rhythmic Layers TechTools to locate in American popular music influences stemming from the African-American church, Latin America and West Africa. Students will then explore the ways "the beat" of this music has, to some listeners, been perceived as "dangerous" while, for others, it is believed that music has been able to challenge obstacles of racism and segregation, bringing people from varied ethnic groups and lifestyles together in ways that words and laws could not.

Learners compare a life-size drawing of a Tyrannosaurus rex head and a full-size Sinornithosaurus body to understand that dinosaurs varied in size. Learners trace individual pieces of a dinosaur on paper and then work together as a group to arrange the pieces of the "puzzle". This is an opportunity to understand scale drawings as well as learn how to work as a group.

This file contains representations and strategies for solving addition and subtraction problems.

This file contains sample anchor charts to create with students. Anchor charts are to be made with students, then displayed as a classroom reference. Parents may also benefit from seeing anchor charts, as they provide a snapshot into the math class.

Students are asked to solve a real world problem, show their work using pictures, numbers or words, and record a matching equation. A scoring rubric is included. The task may be used for instructional or assessment purposes.

This file contains representations and strategies for solving comparison problems. These representations help answer the questions, "How many more?" and "How many fewer/less?" This resource is especially useful for making comparisons when analyzing data.

This file contains strategies and representations for subtraction problems within 20. The images in this file help teachers better understand ways to record strategies on the board and/or anchor charts.

This resource is from Tools4NCTeachers.This resource contains a set of tasks which may be used for instructional or formative assessment purposes.  There are 17 tasks, each on a separate, printable, student work page. Page 1 contains a scoring rubric which may be used for scoring any of the tasks.  Page 2 contains sample student work to support scoring. Remix this resource to include your own student work samples!

This resource is from Tools4NCTeachers.In second grade, students learn to add and subtraction using strategies based on place value and number relationships.  They use a variety of representations such as base ten drawings and number lines.  Second graders do not learn the standard algorithm.  This resource outlines second grade addition and subtraction strategies

In this lesson, students begin to move beyond counting as a strategy for solving addition and subtraction problems. They will use what they know about numbers and relationships between numbers to add and subtract with other strategies. Students will start to see connections between strategies to help them transition their thinking.
