With
this activity, you can visually explore the concept of factors
by creating rectangular arrays. The length and width of the
array are factors of your number.

The
FunBrain Magician will pick a secret number and put it in his
hat.You guess what
number it is.If your
guess is too high or too low, FunBrain will give you a hint.See how many turns it takes you to win!

This
interactive pan balance allows numeric or algebraic expressions
to be entered and compared. You can "weigh" the expressions you
want to compare by entering them on either side of the balance.
Using this interactive tool, you can practice arithmetic and
algebraic skills, and investigate the important concept of
equivalence.

Use
this tool to strengthen understanding and computation of
numerical expressions and equality. In understanding equality,
one of the first things students must realize is that equality
is a relationship, not an operation. Many students view "=" as
"find the answer." For these students, it is difficult to
understand equations such as 11 = 4 + 7 or 3 × 5 = 17 – 2.

Build
up to algebraic thinking by exploring this balance tool using
shapes of unknown weight. Challenge yourself to find the weight
of each shape in one of six built-in sets or a random set.

The
rules of Krypto are simple: Combine five number cards using the
four arithmetic operations (+, –, ×, ÷) to arrive at a "target"
number. This online version of Primary Krypto uses the numbers
1–10 only.

Come
join your friends at the Quotient Cafe, where all the food is
served family style. Everyone sits at one table and shares the
meal evenly. Use your division skills to figure out how much
each character gets. Design your own situation with dinosaurs
dividing waffles, penguins sharing apples, or many other
situations.

By
yourself or against a friend, match whole numbers, shapes,
fractions, or multiplication facts to equivalent
representations. Practice with the clear panes or step up the
challenge with the windows closed. How many socks can you win?

Okta
challenges you to a duel! That crazy octopus wants to play you
in a game where the first person to choose cards with a
specified sum wins. You can choose how many cards, what types of
numbers, and Okta's level of strategy.

By
yourself or against a friend, match whole numbers, shapes,
fractions, or multiplication facts to equivalent
representations. Practice with the clear panes or step up the
challenge with the windows closed. How many socks can you win?

Explore different representations for fractions including
improper fractions, mixed numbers, decimals, and percentages.
Additionally, there are length, area, region, and set models.
Adjust numerators and denominators to see how they alter the
representations and models. Use the table to keep track of
interesting fractions.

How Do You Find the Area of a Parallelogram? In a parallelogram,
opposite sides are parallel and have the same length. This
applet will show you how to divide the parallelogram into
pieces, arrange them together to form a rectangle, and then use
the formula for the area of a rectangle to find the area of the
parallelogram.

How Do You Find the Area of a Rectangle? To measure the length
of a segment, you use a unit length such as an inch, a
centimeter, or a foot, and you see how many times it goes into
the segment you are measuring. To measure an area, you use a
square unit, such as a square inch, a square centimeter, or a
square foot, and see how many times it goes into the area you
are measuring.

How Do You Find the Area of a Triangle? To find the area of a
triangle, find a way to make it look like a shape for which you
already know how to find the area. Try to make a parallelogram
using a copy of the triangle.

Learn how to count, collect, exchange, and make change for
coins. The coin tiles help you count as you learn the value of
each coin. How many of the games can you master?

By
yourself or against a friend, match whole numbers, shapes,
fractions, or multiplication facts to equivalent
representations. Practice with the clear panes or step up the
challenge with the windows closed. How many socks can you win?

Fill a
box with cubes, rows of cubes, or layers of cubes. The number of
unit cubes needed to fill the entire box is known as the volume
of the box. Can you determine a rule for finding the volume of a
box if you know its width, depth, and height?

This
tool allows you to learn about various geometric solids and
their properties. You can manipulate and color each shape to
explore the number of faces, edges, and vertices, and you can
also use this tool to investigate the following question: For
any polyhedron, what is the relationship between the number of
faces, vertices, and edges? What other questions can this tool
help you answer?

Use
this interactive tool to create dynamic drawings on isometric
dot paper. Draw figures using edges, faces, or cubes. You can
shift, rotate, color, decompose, and view in 2‑D or 3‑D.

Quilters and other designers sometimes start by producing square
patches with a pattern on them. These square patches are then
repeated and connected to produce a larger pattern. Create your
own patch using the shapes in the tool below.

This
tool allows you to create any geometric shape imaginable.
Squares, triangles, rhombi, trapezoids and hexagons can be
created, colored, enlarged, shrunk, rotated, reflected, sliced,
and glued together. What design can you create?

With
this tool, you can explore how to decompose shapes and recompose
them to make other shapes. You can draw and cut shapes and also
use slides, turns, and flips to move pieces around.

A
tessellation is a repeating pattern of polygons that covers a
plane with no gaps or overlaps. What kind of tessellations can
you make out of regular polygons?
