• Welcome to Mr. Takenaka's class website,
     
        Welcome to the 2018/19 school year!  This will be the start of my 22th year in teaching and 16th year at CHHS.  I will be teaching Integrated Math 1 this year during 3rd  period. Also, I will be collaborating with Mr. Denny in room 143 during 1st, 2nd, and 6th period.   If you need to contact me during school hours, please email at ryan_takenaka@chino.k12.ca.us.  I rarely check my phone messages and I will get back to you with an email response within the hour or sooner.  Thanks for your time!
