Missing Angle Puzzles

(View Complete Item Description)

This lesson lays some of the ground work for eventually writing two column proofs. In the lesson students use known geometric facts to solve for missing angles. Students are asked to identify the key concepts required for the solution and to record the a path for finding the measure of a particular angle. Key concepts include the sum of the measures of the interior angles of a triangle and quadrilateral, parallel line relationships, and what can and cannot be assumed from a drawing.

Noodles Away

(View Complete Item Description)

This lesson will assist students to see angle relationships and the relationship of parallel lines and transversals. This exercise is good for visual and tactile learners since it is of a concrete nature. Students of all academic levels can enjoy this.

When Does SSA Work to Determine Triangle Congruence?

(View Complete Item Description)

The triangle congruence criteria, SSS, SAS, ASA, all require three pieces of information. It is interesting, however, that not all three pieces of information about sides and angles are sufficient to determine a triangle up to congruence. In this problem, we considered SSA. Also insufficient is AAA, which determines a triangle up to similarity. Unlike SSA, AAS is sufficient because two pairs of congruent angles force the third pair of angles to also be congruent.

Data in the Classroom - Ocean Acidification

(View Complete Item Description)

Investigate ocean acidification through five activities at different levels to learn about ocean acidification using real data. Curriculum Guide available on website.The NOAA Ocean Data Education (NODE) Project is developing curriculum for grades 6-8 designed to help teachers and students use real scientific data to explore dynamic Earth processes and understand the impact of environmental events on a regional or global scale.

Statistical Analysis to Rank Baseball Players

(View Complete Item Description)

As Trudy DentonŐs statistics students assemble their baseball dream team, they must compare and analyze data for four Yankee players and then rank them in terms of their homerun data to fill the last spot on the team.Many factors go into determining which player is the greatest NY Yankee homerun hitter in history. Working in partners, students compare playerŐs data and must reconcile differences such as number of seasons and factors that impact performance. Using Fathom software, students are able to build stacked box plots and complete a comparative analysis of the data before ranking the players. There is a consensus about the top two players but students must defend and explain their choices for the remaining two players.This idea can be easily transferred to other statistical analysis and even modified to suit other grade levels, including middle school.

Free Fall

(View Complete Item Description)

This video lesson is an example of ''teaching for understanding'' in lieu of providing students with formulas for determining the height of a dropped (or projected) object at any time during its fall. The concept presented here of creating a chart to organize and analyze data collected in a simple experiment is broadly useful. During the classroom breaks in this video, students will enjoy timing objects in free fall and balls rolling down ramps as a way of learning how to carefully conduct experiments and analyze the results. The beauty of this lesson is the simplicity of using only the time it takes for an object dropped from a measured height to strike the ground. There are no math prerequisites for this lesson and no needed supplies, other than a blackboard and chalk. It can be completed in one 50-60-minute classroom period.

Measurement & Experimentation Laboratory

(View Complete Item Description)

This course serves as an introduction to working in an engineering laboratory. The student will learn to gather, analyze, interpret, and explain physical measurements for simple engineering systems in which only a few factors need be considered. Upon successful completion of this course, the student will be able to: Interpret and use scientific notation and engineering units to describe physical quantities; Present engineering data and other information in graphical and/or tabular format; Use automated systems for data acquisition and analysis for engineering systems; Work in teams for experiment design, data acquisition, and data analysis; Use elementary concepts of physics to analyze engineering situations and data; Summarize and present experimental design, implementation, and data in written format; Use new technology and resources to design and perform experiments for engineering analysis.

Repeating Decimals

(View Complete Item Description)

This lesson unit is intended to help teachers assess how well students are able to: translate between decimal and fraction notation, particularly when the decimals are repeating; create and solve simple linear equations to find the fractional equivalent of a repeating decimal; and understand the effect of multiplying a decimal by a power of 10.

Proportion and Non-proportion Situations

(View Complete Item Description)

This lesson unit is intended to help teachers assess whether students are able to: identify when two quantities vary in direct proportion to each other; distinguish between direct proportion and other functional relationships; and solve proportionality problems using efficient methods.

10X Bigger!

(View Complete Item Description)

Students will explore multi-digit numbers and the relationship between ones, tens and hundreds; a digit in one place is 10x the digit in the place to its right. Students will use their bodies to represent digits in multi-digit numbers up to the hundredths place and compare these numbers using <, =, >. Students will use their bodies as multi-digit numbers to add and subtract.
