What is potpourri math

This month's activities are designed to involve students with a wide variety of mathematical tasks. The activities should help students realize that mathematics can be recreational, as well as educational. Students will have fun solving problems in their environment or engaging in mathematics games and puzzles. During summer vacation, you might search the Internet for fun puzzles and mathematics activities. Here are some sites to get you started:.

Go on an outside walk to collect rocks, leaves, flowers, seeds, and other natural items. Secretly think of one way to sort your collection, such as things with leaves and things without leaves. Ask a friend to tell you the categories that you have used in your sorting.

Now ask your friend to sort the objects in another way; then you will work to discover those categories. See if you and your friend can sort the objects in a way that would be difficult for a classmate or even the teacher to figure out.

Why are these two vocabulary words the one that this student confused? I see this a lot. I suppose a perpendicular can be a specific transversal that uses right angles, which could account for that one. Jim — very interesting. During the printing of La geometrie…the printer reached a dilemma.

Choose Plot New Function from the Graph menu. Click on x in the Function Calculator or type x from your keyboard. Select the plot you just created and the independent point whose coordinates you measured. Drag the point along the plot and observe its coordinates. To change the domain, drag the arrows at either end of the plot. Drag the unit point—the point at 1, 0 —to the right and left and observe how the scale of the coordinate system changes.

Release the unit point when the x-axis goes from about —10 to Choose New Parameter from the Graph menu. Enter m for Name and 2 for Value and click OK.

Use the same technique to create a parameter b with the value —1. The New Parameter dialog box Mac. Select, in order, the radius measurement and the circumference measurement. Choose Plot As x, y from the Graph menu. Can you see your point?

If not, it might be off the screen. Drag the new unit point at 0, 1 down until you can see the plotted point from the previous step.
