Monday, April 10

In class: Module 6 test.

Graded: Module 6 work. Students received their Module 6 Binder Check sheet back after the test with behavior scores for this unit. Feel free to check this with them this evening. Let me know if you have any questions.

Thursday/Friday Update

Yesterday complete 10.2/10.3 worksheet. (period 5 assigned only 10.3). Today in class we did practice problems finding volume and surface area of pyramids given only minimal information about their side lengths and students needed to find many unkown lengths using right triangles. No HW today.

Thu/Fri Update

I postponed today's test until Monday so that students would have time to finish review problems and work in class today. Yesterday and today's assigbment was to complete a review packet.

We have the Module 6 test on Monday. : end

Wednesday, April 5

Today's assignment: Complete 10.3 on p. 524: 1-12, 17-23.

Topic: Volume of pyramids and cones. Also, we discussed the difference between feet, square feet, and cubic feet.

How many people do you think would fit into one cubic mile?

Tue April 4th

Hi All —

It is nice to see everyone again, and I hope that you were lucky to spend Spring Break doing something interesting! I spent a lot of time at the pool and the park,  my daughter, Alma, loves to "hang at the park" which means literally going to the park and hanging off as many bars and rings and railings as she can find. So we did lots of "hang at the park" and her current favorite book is "Nanette's Baguette" — highly recommended. For. Two. Year. Olds. And also grown ups!

I wanted to give you an update on what's going on in class and I realized that I should also communicate to you about a change of expectations for these emails.

"Almost Daily Email" becomes mostly daily but loses content

I've been thinking about my emails/lack thereof as of late and wanted to send out a more general email and update you on what's going on from my end. Since my son was born my duties before/after school have shifted and I now do the morning routine dropoff and pickup for my daughter most days before and after school. This has made it very difficult for me to send regular email updates to you after school before my daughter goes to bed at around 7:30pm.

The best solution for me is to switch from sending an explanation to simply sending an email containing the assignment for the day. I will try to send this out during or right after class so that you have the day's assignment, but I will not necessarily include narrative or explanation. So, the body of the message might be something cryptic like

Today's assignment: complete the chapter 7 practice problems (handed out in class) and study for your Chapter 7 test on Thursday

I'm sorry I haven't been able to send the same level of updates as I would like, I know that communication is important but at the moment I need to prioritize a bit. As always, if you have questions for me please feel free to send me an email.

In class today we worked on an in-depth example problem from the test and had some time to work on other test review problems.

Chapter 7 Test is on Thursday. Students will take their Chapter 7 test on Thursday. And again, if you would like the list of skills they should have

Seeing this list again I think it is missing solve quadratic equations by completing the square and derive the quadratic formula by completing the square on the equation 0 = ax^2 + bx + c.

Tuesday, Apr 4

Today's Assignment

1. Complete the conjectures in chapter 10.2 (A-C and Prism/Cylinder) from pages 514-6

2. Complete 10.2 on p. 517-20: 1-14, 19-26

Handed back: Chapter 9 test from Friday before Spring Break. Scores will go in Synergy at the end of the day perhaps 🙂

Tue, Apr 4

Today's Assignment: 6.7 Task + RSG.

Reminder test on Friday students will need to be able to

  • Perform reflections, rotations and translations.
  • Identify sequence of transformations that map a given pre-image onto its image (play detective)
  • Solve transformation problems with and without coordinate points (equation of lines)
  • Use geometric vocabulary: chirality, orientation, preservation of angle measure/side length, n-fold reflection symmetry, n-fold rotational symmetry …
  • Find missing side lengths in right triangles
  • Answer questions about definitions and properties of triangles, quadrilaterals, and regular n-gons.

Change to these emails + a few class updates

Hi students and parents in Geometry —

It is nice to see everyone again, and I hope that you were lucky to spend Spring Break doing something interesting! I had out of town nephews come visit which was great. We took Alma and Evan (now 2 months) to see the please-don't-touch-the-legos at OMSI. Wow! That was amazing, but also, a bit stressful keeping two year old hands from touching lego sculptures at eye level. We spent lots of hours climbing and sliding and I even read a few pages of a book… for fun!

Ok, so on to the business at hand. I need to change expectations for these emails a bit and wanted to let you know what's going on in class.

"Almost Daily Email" becomes mostly daily but loses content


I've been thinking about my emails/lack thereof as of late and wanted to send out a more general email and update you on what's going on from my end. Since my son was born my duties before/after school have shifted and I now do the morning routine dropoff and pickup for my daughter most days before and after school. This has made it very difficult for me to send regular email updates to you after school since I have no planning time on A-days and during my plan time on B-days I have a number of responsibilities to balance including email writing. Email updates don't make much sense if I send them after my daughter goes to bed at 8pm because you probably don't want to check for them, and, again, I have other school work to take care of as well. The best solution for me is to switch from sending an explanation to simply sending an email containing the assignment for the day. I will try to send this out during class or right after 3rd period during lunch so that it is there, but I will not necessarily include narrative or explanation to go along with the assignment, it will just say something like

Today's assignment: complete 10.1 on p. 508: 1-35, 38-41

I'm sorry I haven't been able to send the same level of updates as I would like, I know that communication is important but at the moment I need to prioritize a bit. As always, if you have questions for me please feel free to send me an email.

Current unit: Volume in the real world

We are focusing on volume in the real world for our next chapter. Students will learn about a variety of topics related to volume, including how to derive volume formulas for a variety of shapes including prisms, pyramids, cones, cylinders and spheres.

Our end of unit assessment will involve students creating their own question that CANNOT be googled. This question will likely follow a format like "What would it look like if … ?" Last year a few examples of questions are

  • If you gathered up all the cell phones on earth that have ever been made, and put them into one giant conical pile, how would that pile compare to Mt. Hood?
    • This questions involved a number of interesting estimations (the student considered the changing volume of cell phones through the years) the dimensions of the pile.
  • What would it look like if I stored all the water that falls on my roof in a barrel next to my house?
  • If all the CO2 in the atmosphere were to suddenly separate out of the atmosphere and form a sort of ring around the surface of the earth at sea-level, how thick would a typical person be able to breath fresh air when sitting, standing or sleeping?
  • If all the air I breath today were to be compressed into a set of weights at the gym, could I bench press my breath? Could the average american? Could I bench press my breath for a week or a month?

Smarter Balanced testing will take place in math during May.

If you made it all the way down to here, bravo! Thanks for reading and let's have a great spring!
