### The Real Number Universe (The Realverse)

I must confess that i have a love for these Real Number themes. Here our latest variation, The Realverse.

An awesome idea would be for your students to list some crazy properties about each world. For example, in Natural World, everyone grows directly from 2 feet to 3 feet. Or, everyones age on the planet is in natural numbers

### Absolute Value's and Magnets

Here is an awesome idea for helping young students remember that absolute values are positive numbers using magnets

Materials Needed:
Magnets and popsicle sticks

Place two of the magnets under a piece of paper and glue them both south side up.
Label the third magnet negative 3 on the south end and positive 3 on the north end

Now drop the magnet as follows (see video) to show how absolute values are always positive

### The Real Number System Zoo

There are tons of ways for teaching the real number system without relying simply on drill and kill. This is an awesome project. As you can see, nothing is labeled except the numbers themselves. This way your student must explain the project to you--helping him solidify his or her memory of the terms

### Happy Meals and Math

I'm envisioning a double lesson here. Proportions & Volume/Area of Irregular Shapes (with a built in lesson, if you would like, on choosing the right quantity of food per serving).

Foremost, have your students bring in a happy meal box sometime within two weeks prior to the class, labeling everything that came in the box on the inside of the box with their name. You may want to swing by your local McDonald's and ask for extras for those who forget (don't forget to bring your teacher badge).

Next, you can go here and figure out the calories of each item. Or download the pdf

 Next, have your students figure our what the proportion of calories in one Happy Meal is to their daily allotted proportion of calories per day , of which 2000 is probably a safe estimate. Happy Meal/Calories Per day Next, Looking at the shape of the Happy Meal box you can see an irregular figure Thus, have your students attempt to calculate the Area of the sides or Volume of the box. Good Luck!

### The Real Number Diorama. Shoebox & Math

The Real Number Sea

This was fun. Notice that each of the foam sea creatures correlates in some way to the real number system.
