Investigations Unit Training: December 8 and 9

SpringCreek Leaders Spill the Beans on Trapezoids

SpringCreek students have combined excellent camera work with very clear articulation to produce two fine examples of trapezoid geometry. Pay attention, now! Your teachers, Rain and Taleah, are about to take the stage...

I visited SpringCreek earlier in the week, and observed these students measuring other geometric shapes, like cylinders and spheres. I wonder if we'll see a report on the size of a basketball vs. the size of the hoop we try to toss it through? Hmmm??? Hint hint! ;-)

Why Can We "Add Zeros" When Multiplying by a Power of Ten?

Somewhere along their mathematical journey, every student is taught the "trick" of "adding a zero" to any number they multiply by 10. First of all, let me be clear - we know we aren't actually adding zero, right? Because if we add zero to any number, we end up with that same number thanks to the zero property of addition.

So if we aren't actually adding zero, or zeros as the case may be, what the heck is going on when we multiply by a power of ten?

Recently, I challenged the 5th grade teachers at South to have students answer this question. Mrs. Seger's mathematicians have risen to the challenge!

TCMS Adds One... No, Two... Hold On.. That's SIX New Videos!

Need to find the area of a trapezoid, and need it NOW??? The TCMS has you covered with SIX, yes SIX videos to give you plenty of practice. Enjoy!

Klein Answers the Call!

Nice work, Jesse! I liked the way you showed us how we could construct a parallelogram and use that to find the area of a trapezoid.

Trapezoid Challenge: Littleburg in the House!

Excellent! Wonderful presentation... We look forward to more from you!
