Mr. Duncan

Tori, Noah, and Hunter at the UIL competition. Tori and Noah aced the preliminary round and are advancing to the finals for Informative Speaking.

Ops check good! Nathan just tested all his connections, and he’s ready for the UIL Computer Apps competition. @risdHS #RobinsonISD

Sydney, Kelsie, and Alexis are getting ready for the UIL Academic Competition at Connally today, while Omari and Tyler are working Math problems on a practice test. RNQ! #RobinsonISD @risdHS

Engineering Math: This is a trial run of the Chimichangas’ robot (Team Cassidy, Morgan, and Ida). This robot has a good gear system, which gives it a good Mechanical Advantage to lift the one pound weight. Well done! @risdHS #RobinsonISD

Made my day to have these 3 past students come back and help me with class today. #rocketsreachingout It was a lot of fun having them back in class! Thanks. @RISgreatness #robinsonISD @risdHS

Mr. Duncan’s 2nd period boys showing the intermediate school students the right way to do the Jingle Bell Dance! @risdHS #RobinsonISD #RocketsReachingOut

Rockets Reaching Out! Mr. Duncan’s Geometry class traveled to the intermediate school to help teach younger students. @risdHS #RobinsonISD #RocketsReachingOut

I measured the 40 degree angles, and I measured the 18 inch and 13 inch sides. Whether you call it Angle-Side-Side or SSA, it does not work to prove two triangles are congruent.

Here is a good vocabulary word for our Engineering Math classes. We are building bridges out of spaghetti. @risdHS #RobinsonISD

Ok. We didn’t win the door competition, but I think our door is great. Thank you 2nd period! @risdHS #RobinsonISD

Thank you Mr. Gore. This is the best theme, ever. (I am a little bit biased.) We went to the game last night, and I really like the new band uniforms. We look good. Bravo Zulu. @risdHS #RobinsonISD

We had a great day today! We worked in groups to solve problems in Geometry and Engineering Math classes. Strategizing. Helping. Communicating. Laughing. Optimizing. Working as a team for a common goal. @risdHS #RobinsonISD

We are getting a great lunch with such amazing views. Thank you @ltcollins @risdHS #RobinsonISD

RHS teachers at lunch. Awesome view! @risdHS #RobinsonISD

Awesome tweet. Thanks for making me laugh! #risdcsisd

All our teachers and staff at China Spring for a motivational Convocation. Shine Bright @risdHS #RobinsonISD

@rocketcoachta @risdHS You just go out and win the football games. <smiles> Coach Snow has been giving me retroactive lessons on football rules. RNQ!

@GeometryRHS @risdHS Wish I would have had Mr Duncan as my Geometry teacher. He is awesome!! @risdHS

Welcome back, my Geometers! I got new kicks for the new school year. These are PG 2s. See you Tuesday, Aug 21st. RNQ! @risdHS #RobinsonISD

To all my manga lovers out there, Keep drawing! Also, Math is cool! @risdHS #Robinsonisd @ltcollins
