## 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 Atom

View twelve atoms each composed of different numbers of protons, neutrons and electrons. Determine whether the atom is an anion, cation or isotope and identify the element on the Periodic Table.

## Name That Function

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

## Networks

Learn about the different mathematical tools used to analyze and describe networks. Practice building networks that meet specific criteria.

## 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.

## Newspapers: Use Your Document Detective Skills

Read three newspaper articles, one at a time, about events of historical significance. Identify the region and era particular to each newspaper article, and answer additional questions about the topic covered.

## 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.

## Numbers in Nature

Many Renaissance artists and architects used the concept of the golden mean which was thought to be visually pleasing. An Italian mathematician developed a series of numbers related to the golden mean; see if you can detect the pattern.

## 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.

## The Path of a Case

You just graduated from law school and want your first case to go all the way to the Supreme Court. Read some case summaries and pick a case you think will make it to the Supreme Court.

## 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.

## Periodic Table Assessment: Test Your Skills

Test your knowledge of atoms, orbitals, periods/groups, characteristics of families, isotopes and relative mass. Take this 39-question test, review your correct and incorrect answers, and print out your assessment.

## The Periodic Table

Go through the Periodic Table piece by piece and learn how it works. Also, figure out how and why elements interact to make the world you see around you.

## The Perpendicular Bisector

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