Pero hindi nga pala kayang baguhin ang guhit ng
palad dahil ilang beses ko mang iwasan ang
propesyon ng pagtuturo, tila batubalani ito na hinihila ako
para magsulat gamit ang yeso at pisara (wow, lalim nun ah!)

Extra Credit Points

in rare occasions I give credit point through asking students random
questions from world geography to pop culture…


To teach is to learn twice

I don’t usually give out extra credit points
to boost my students grade up. However, I thought
it would be great to give them a chance
to change their lowest scoring test by creating a
flipped video on a math test that they did poorly on.

Happy twenty-fourteen!

I got passed the awkward feeling of seeing myself
teach on videos. It’s been a big struggle at
the beginning and overcoming the weird feeling of listening
to my voice is liberating– making flipping classroom a lot easier.

Thank you for a great resource! I have AP Stat, Precal, AP Calc AB and Geometry preps this year and I’m going to miss the first two weeks of school due to surgery. I definitely plan to incorporate some of your Powerpoints into my sub plans, even the Alg I material that will have to be reviewed the first two days in Geometry.
