Preview Problem-Solving Resources

Grades 6-8 Professional Learning and Instructional Resources

Preview Problem-Solving Resources are designed to review grades 3-5 concepts and strategies involving fractions, decimals, and computation while introducing foundational grade 6-8 math concepts such as rational numbers, ratios, rates, and percents. These resources help teachers to connect review topics, such as locating and labeling fractions and decimals on number lines, directly to essential grade 6 strategies and concepts, such as representing negative rational numbers.

These resources are built around videos that structure a problem-solving talk with a class or small group of students. The video briefly reviews essential representations, strategies, and concepts. Then, students are challenged to build representations and solve problems using a set of magnetic manipulatives on a whiteboard. Instructional notes for the video help teachers focus their questioning strategies and identify pause points in the video to address diagram comprehension, concept development, and vocabulary. Finally, students apply what they have learned through daily problem-solving tasks and practice pages.

PPS Video —Represent and Solve Ratio, Rate, and Percent Problems

Preview Problem-Sloving Video

Structure a Problem Solving Talk

Preview Problem Solving Videos review essential concepts from grades 3-5 and preview representations and strategies from grades 6-8. For example, many students entering middle school have a weak understanding of how measurement is used to locate and label whole numbers, fractions, and decimals on number lines. The sequence of PPS Videos starts with a review of plotting whole numbers, fractions, and decimals on number lines. Then, students apply these strategies to locate and label negative integers, fractions, and decimals.

PPS Resources help teachers implement these problem-solving videos with a class or small group of students. These resources include a magnetic manipulative kit for whiteboards, instructional notes, application tasks, and practice pages.

Sample PPS Video — Measure to Plot and Label Positive and Negative Fractions

Review and Preview Topics in this Sample PPS Video


REVIEW and PREVIEW — Positive and negative fractions on number lines represent their distance and direction from zero. 


REVIEW — The length of a unit-fraction bar is defined by the number of equal-length bars that measure a length of 1. 


REVIEW — Two numbers that measure the same distance and direction from zero on a number line are said to be equivalent.

REVIEW — Represent fractions greater than 1 .


PREVIEW — Positive fractions can be reflected across the tick mark for zero to locate the opposite negative fraction.



Problem Solving Challenges in this Sample PPS Video

Each PPS Video includes a series of Problem-Solving Challenges that are solved as a class or small group. Students use manipulatives from the Magnetic Manipulative Kit for whiteboards to apply strategies demonstrated in the video.

For this PPS Video, Measure to Plot and Label Positive and Negative Fractions, students:

  • Use magnetic number line segments to build the number line.

  • Apply measurement strategies from the video to plot and label fractions on the line.

  • Learn that measurement strategies to plot and label positive fractions to the right of zero can be applied to measure, plot, and label negative fractions to the left of zero.

Video Overview and Instructional Notes

Develop Questioning Strategies

The Video Overview and Instructional Notes outline the conceptual highlights of the PPS Video and list the essential strategies and concepts that are introduced and reviewed. In addition, video pause points with instructional notes identify important representations, strategies, and concepts and offer suggestions for facilitating discussions and problem-solving with students.

The instructional notes offer questioning strategies for each Problem-Solving Challenge and identify other pause points with notes on:

  • Diagram Comprehension

  • Essential Concept Development

  • Vocabulary Discussion

  • Problem-Solving

REVIEW Pause Points

The first three pages of this VOIN review the basics for measuring to locate and label fractions on number lines.

  • Identify unit fractions bars

  • Measure to fractions less than and greater than one.

  • Identify equivalent fractions and whole numbers that measure from zero to the same point on the line.

PREVIEW Pause Points

The Preview pause points on this page challenge students to apply the measurement strategies to plot and label negative numbers to the left of zero.

  • The mirror image of a positive number across zero is the opposite negative number.

  • Negative numbers measure a distance to the left of zero, where measurement bars represent distance and the arrows (or vectors) represent both distance and direction from zero.

  • Then, students are Challenged to use magnetic measurement bars and fraction strips to locate and label negative fractions on a whiteboard number line.

Daily Problem-Solving Tasks

Review of Essential Concepts and Strategies

Daily Problem Solving Tasks are represented on the whiteboard using the Magnetic Manipulative Kit so that students entering the classroom can review the tasks and solve the problem. Then, to start class, students can briefly share strategies to solve the problem. These short tasks allow teachers to review important strategies and concepts introduced in the PPS Video.

Daily Problem Solving Tasks

Problem-Solving Practice Pages

Ongoing Practice of Problem-Solving Strategies

The Problem-Solving Practice Pages challenge students to apply the concepts and strategies that were introduced in the PPS Video and reviewed in each Daily Problem-Solving Task.

For PSP Pages 1 and 2 for this sample video, students use the Equal-Parts Ruler (see below) to measure and plot fractions on the number line. On Pages 3 and 4, students interpret equally-spaced tick marks as marking off equal-length measurement bars to locate and label fractions. Students apply their understanding of measurement bars to interpret equally spaced tick marks, focusing students on the equal increments between the tick marks and not on counting the number of tick marks.

Measurement-Bar Rulers

Students use measurement bar rulers to plot and label points on number lines on this set of PSP Pages. These rulers allow students to practice measurement strategies introduced in the PPS Videos. Sets of rulers are printed from a downloaded PDF.
