An interactive applet and associated web page that provide step-by-step instructions on how to divide a line segment into any number of equal parts, using only a compass and straightedge. The applet starts with a given line segment and ends with that segment divided into n parts. In the applet n=5, but the construction works for any n. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. The text on the page has printable step-by-step instructions. Applet can be enlarged to full screen size for use with a classroom projector.

Today we’re going to talk about data relationships and what we can learn from them. We’ll focus on correlation, which is a measure of how two variables move together, and we’ll also introduce some useful statistical terms you’ve probably heard of like regression coefficient, correlation coefficient (r), and r^2. But first, we’ll need to introduce a useful way to represent bivariate continuous data - the scatter plot. The scatter plot has been called “the most useful invention in the history of statistical graphics” but that doesn’t necessarily mean it can tell us everything. Just because two data sets move together doesn’t necessarily mean one CAUSES the other. This gives us one of the most important tenets of statistics: correlation does not imply causation.

An interactive applet and associated web page that demonstrate the corresponding angles that are formed where a transversal crosses two lines. The applets cycles through the four possible pairs of angles when in animation mode. By dragging the three lines, it can be seen that the angle pairs are congruent only when the lines are parallel. When not in animated mode, there is a button that cycles through each the four pairs of angles. The text on the page discusses the properties of the pairs of corresponding angles both in the parallel and non-parallel cases. Applet can be enlarged to full screen size for use with a classroom projector.

Counting Collections is an important mathematical routine that students or families can do with very little guidance at home. Teachers could make kits with available resources for use at home, or send suggestions for commonly found objects that families could use for counting practice at home.
Counting Collections are just as described; they are collections of items that students count. Depending on your students, you will need several different kits. Kits hold several different collections of items.

Ten printable colouring pages which depict the numbers one through ten. Each page has a spelled-out number in Michif, the language of Métis Peoples’, as well as the numerical equivalence. There are also images of culturally significant items on each page, which correspond with the respective number. There are written instructions on the bottom of each page that indicate different activities that supplement the colouring pages.

Welcome to Crash Course Statistics! In this series we're going to take a closer look at how statistics play a significant role in our everyday lives. Now this a "math" course, and there will definitely be some math, but we're going to focus on how statistics is useful and valuable to you - someone that performs AND consumes statistics all the time. Statistics are everywhere from batting averages and insurance rates to weather forecasting and smart assistants, and it's our hope that when you finish this series you'll get a better idea of the role statistics play in helping us better understand the world!

Graphs and charts are great because they communicate information visually. For this reason, graphs are often used in newspapers, magazines and businesses around the world.
NCES constantly uses graphs and charts in our publications and on the web. Sometimes, complicated information is difficult to understand and needs an illustration. Graphs or charts can help impress people by getting your point across quickly and visually.
Here you will find five different graphs and charts for you to consider.

My goal was to bring 21st Century Competences with the focus of critical thinking into my Gr. 2 Math classroom. I show a droodle – an abstract drawing. I ask students to take a few moments and think about what it could be. Then they can discuss with a partner, and finally share what they thought. Afterwards we have a discussion around “right” and “wrong” answers – which is a common way to think around math. No one is wrong – these are all good ideas that could answer the question: What could this be?

An interactive applet and associated web page that demonstrate the properties of a cube. A 3-D cube is shown in the applet which can be interactively manipulated using the mouse. Research has shown that some younger students have difficulty visualizing the parts of a 3D object that are hidden. To help with this, the student can rotate the cube in any axis simply by dragging it with the mouse. It can also be 'exploded' - where a slider gradually separates the faces to reveal the ones behind. The cube can also be made translucent so you see through it to the other side. Applet can be enlarged to full screen size for use with a classroom projector, and printed to make handouts.

An interactive applet that allows the user to graphically explore the properties of a cubic equation. Specifically, it is designed to foster an intuitive understanding of the effects of changing the 4 coefficients in the function. The applet shows a large graph of a quadratic (ax^3 + bx^2 +cx + d) and has four slider controls, one each for the coefficients a,b,c and d. As the sliders are moved, the graph is redrawn in real time illustrating the effects of these variations. Applet can be enlarged to full screen size for use with a classroom projector.
