#Teach180: Days 121-130

This year I've taken on the #teach180 challenge.  The challenge is to post one tweet per day showing a glimpse inside your classroom.  I'm also putting the tweets together in a biweekly blog so that I can share the resources that I'm tweeting about.

Day 121: Today we had our weekly cumulative quiz.  The end of the marking period is just about 2 and a half weeks away.  Crunch time in showing mastery of this marking period's objectives.

Day 122:  Today in geometry we practiced finding the area of regular polygons using this color by number assignment.


Day 123:  Today in algebra 2 we practiced solving word problems using systems of quadratic systems by using this worksheet.  Nothing fancy, just basic practice if you'd like to use it.

Day 124:  Today in geometry we used Khan Academy to practice finding the missing side of a parallelogram given its area and another side.

Day 125:  Today in algebra 2 we practiced evaluating rational exponents using these task cards.  It's been too long since I used a good set of task cards.  They really make the practice set more accessible to students and less intimidating as a bid worksheet.

Day 126:  Today was another weekly cumulative assessment. Only 2 more quizzes this marking period.
Day 127:  Today in geometry we used EDpuzzle to learn about finding the surface areas of prims and cylinders.

Day 128:  Today in algebra 2 we practiced solving equations with rational exponents using this error analysis assignment.  I did not create it, and at the moment, I don't remember where I downloaded it from.  I'll be sure to update this once I know who to give credit to.  I love error analysis assignments.  Especially ones where some questions are solved correctly and some are not :)
Day 129:  Today in geometry we learned about finding the surface area of pyramids and cones.  I don't really like the way that I taught finding area of regular polygons this year (A=1/2ap) or the way that the use of this formula turned out.  I think that if I end up teaching this class again next year, I won't give specific formulas, but use decomposition instead.  I showed the students decomposition as well this year, but showing the specific formulas ruined their understanding of what surface area really means.  That's the life of a teacher I suppose; always changing and improving.


Day 130:  Today in algebra 2, we practiced verifying that functions are inverses using function composition.  Weirdly, once students got the hang of composition, they thought this procedure was very satisfying.  They liked how everything simplified to just 'x.'
That's it for this round of #teach180.  It's never too late to join in the fun!
