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 :)

Quadrilaterals and Pop Tarts

Slight variation of the polygon post, now were making quadrilaterals. It's not as easy as you may think, the pop tarts end up falling apart

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
