I also like showing the students that they can use them to catch up if they miss class or are confused about a topic.]]> 2022-08-03 15:04:42 UTC https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2254216132 https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2254216778 My students tend to have trouble going back to Algebra I in calculus. They think tangent line problems have to be difficult. It takes a long time to convince them that they need to find a point and a slope and write the equation of a line!]]> 2022-08-03 15:05:45 UTC https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2254216778 https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2267633107 I often use these video to intro. a topic and then just have students work examples in groups on the whiteboard! ]]> 2022-08-22 16:39:21 UTC https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2267633107 https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2267634872 Students often make mistakes in my class when I have them approximate a value before the point of tangency, the always miss negatives.]]> 2022-08-22 16:40:53 UTC https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2267634872 DESMOS https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2267636583 Just found a Desmos Activity for this that I LOVE!

Although 10 minutes or so is not that long, I would not want to lose those 10 minutes. I do like the Khan Academy and the AP classroom videos for this lesson, and I like that the students could then answer some AP questions or they could answer the Khan Academy questions at the end to check their understanding. I would assign this as intro homework. billie_burris https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2641966014 2023-07-10 16:44:32 UTC https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2641966014 Videos in Class joshuamikemartinez https://padlet.com/NMSITTT/99nqomhgrgceara6/wish/2658910538 I may have students watch videos in class, but I would be more likely to have them watch outside of class and then discuss during class tine.
