Solving Equations Using Weigh Scales
The following is a hand drawn experiment, however, i believe it would best be received if the educators actually used a scale and a real doggy-bowl(or a paper bag) on both sides to represent the variable as well as actually manipulated the experiment so as to show how the scale must balance. Thus, i'm well aware that the hand drawn experiment here is flawed...but i think you'll get the idea :)
How Many Bones Are In The Dog Bowl
Use Algebra To Solve
Now look in the dog bowl to see if you are correct?

Teaching the Value of the Pythagorean Theorem with a Football Field
Activity: Teaching the Value of the Pythagorean Theorem with a Football Field
You will need:
Yard sticks
Pen and paper
(Measure using inches to avoid added conversions)
Overview of Activity:
Students will be split into groups and placed at the four corners of the end zone of a football field. Using a yard stick students will measure how many yards are from one corner of the end zone to the other. After the activity, the students will be shown how they could have easily calculated the distance by simply using the Pythagorean Theorem.
Pre Activity:
1. How to measure using a yard stick.
2. How to keep record of each yard stick using tally marks
Activity:
1. Have Students split into four groups
2. Ask them to measure how many yard sticks reach from one corner of the end zone to the other (the hypotenuse of the triangle).
3. Place each group at each corner of the end zone and have them measure how many yards from one end zone to its diagonal.
4. Have them record their data
Post Activity:
1. Have students share their data and compare it to your own
2. Share the way you calculated the distance using the information that the field is a rectangle with a distance of 120 yards and a width of 50 yards)
3. A^2 + B^2 = C^2, A= 120, B= 50. C = Square root(16900)
4. Introduce the Pythagorean Theorem
5. Practice

Hiring Your Students As FBI Agents (Cool Way to Teach Area and Circumference of Circles)
Let face it, circles are just not that exciting for math students, especially the area and circumference of circles.
Let’s change this...
Let’s change this...
First, hire all your students as FBI agents
Next, they must begin working immediately, as there’s an emergency. Somewhere in the school (you may use town if you would like) is a bomb with a blast radius of 500 feet!
Our job is twofold: We need to know how far back the citizens need to stand to insure their safety (circumference of a circle). Second we need to know what type of damage we are looking at (area of circle).

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

Moving From Rectangle Paper To Other Polygon Paper
You may find it helpful when teaching about various polygons to actually have your students take all their notes on a specific polygon shaped paper. Students normally take all their notes on rectangular ruled paper so , try trapezoid paper. Each day you can switch up the shape. (Any ideas for the unused portion of the paper?)
Or Octagon Paper

Another Variation of Teaching The Real Number System:
Divide your classroom desks into a real number system so that each desk represents a place in the number system.
You may randomly assign each student numbers or make them draw from a cup. Its also a good way to play musical chairs. They must be seated in a desk in the right spot of the room i.e. the correct spot in the number system before the music stops or they are eliminated. As always, send me pics or ideas if you have them :)

Pop Tarts and Polygons
Thought of this while eating a Pop Tart with my son
Have your students bring in their own Pop Tarts, you provide the plastic knifes.
1) Start With a Pop Tart Quadrilateral
2) Ask your students to make a Pop Tart Pentagon by cutting off a corner (and eating it)
3) Now make a Pop Tart Hexagon
...and so forth till you reach a decagon (send me pics)

Teaching Number Sets With A Twist
Whole, Natural, Integers, Rational, Irrational and Real definitions are hard to remember for the students, especially when they must know which numbers go where. I have posted lots of ideas about how to teach this but thought of another form--using blueprints
Have your students work in groups to create blueprint for a house that all types of numbers could live in while maintaing the House Rules (i.e. no zeros in the natural numbers' room, no fractions playing in the integer section of the house). Please send me pics if you try this
