Teacher professional development and classroom resources across the curriculum

## The Midline Cut

You can cut geometric figures into pieces that you can rearrange to form different geometric figures. Show how the midline cut of any triangle can be used to form a parallelogram. View non-Flash version.

## MiniMouseLab

Use a simulation to operate an elevator and see its motion. Examine the graphs that describe the motion you produce.

## Modeling Fractions With Cuisenaire Rods

Learn how to represent fractions with Cuisenaire Rods. Use these rods to perform operations with fractions.

## Monarch Butterflies

Observe monarch butterflies and report their sightings online. Share and review the sightings with other students/classrooms to track hemispheric migratory patterns.

## Ms. Anwar's Backyard

Use the slider on the graph to see all possible shapes of Ms. Anwarâ€™s 2,000 sq. ft. backyard. Come up with an equation relating the length (x) and the width (y).

## Multiplication with Manipulatives

Area models can be used for many types of multiplication problems. Work with manipulatives to create area models for some multi-digit multiplication.

## Music Mentor

Detect musical errors and strengthen music-reading skills. Taking on the role of a mentor, students listen to a peer perform musical phrases shown on screen, and must offer feedback to help improve the performance.

## Mystery Operations

The computer makes up a mystery operation and you have to figure out what it is. Keep entering pairs of numbers for the computer to calculate and try to find the pattern in the answers the computer gives until you think you know what's going on.

## Name That Function

Chart graphs of three equations. State whether each graph is quadratic, exponential or linear and explain your reasoning.

## A New Identity

Students have written one-paragraph self-descriptions to send to other citizens of the new state they are creating. Read one of the paragraphs and work backwards through a series of prompts to determine the paragraph's audience, purpose, genre and theme.

## Nonstandard Units

Use the set of three triangles to build each of the outlined polygons. Then use the triangles to determine the area and perimeter of each polygon.

## Noteflight

Compose and arrange scores. In the Noteflight online community, musicians and educators create, adapt, find, and share music for their musical needs and the needs of their students.

## Operations in Base Four

Strengthen your understanding of place value by looking at systems based on numbers other than 10. Work with manipulatives to calculate base four addition and subtraction problems.

## Ordering a Stem and Leaf Plot

Stem and leaf plots are a method for showing the frequency with which certain classes of values occur. You will create an ordered stem and leaf plot.

## Ordering Hats

Click through each representation to see how the display of relative frequency relates to the display of cumulative frequency and their corresponding histograms. Examine how each method is useful for summarizing the variation in numeric data.

## Organizing Data in a Stem and Leaf Plot

A stem and leaf plot is a graphical representation for investigating variation. You will convert an ordered stem and leaf display grouped by tens into an ordered display grouped by fives.

## People Patterns

Observe a line of people, discover a pattern and figure out who should come next. See if you can complete a pattern of 10 people before the penalty word "Pattern" is spelled out.

## The Perpendicular Bisector

Watch as the triangle is reflected over the perpendicular bisector. Practice reflecting other figures.
