{Geo B} Quiz and Quiz and Tests, Oh My!

Wednesday this week there was a pop-quiz.  Your student may need a hug.  Regardless Quiz redoes are available for students and should be turned in no later than Tuesday next week.

Monday next week (Tuesday for 7th hour) is another quiz.  They know this one is coming.  It's been announced.  It's posted here.  It will cover 7-1, 7-2, 7-3 and 7-5.  The only thing that won't appear on the quiz is the collection of problems related to how Perimeter and Area are related to scale factor.  It will appear on the test.

Wednesday next week is the Chapter 7 BA.  The preview will be posted in Skyward this weekend for those that want to look over the specific objectives that will be on that test.

Have a great weekend!

{Geo B} {Geo Essentials} Snow Day Extra Credit

On this surprise (for me) snowday here's a little challenge.

Imagine that the snow never stops falling.  Either by using your own estimation, or a weather report, find the rate of snow fall at the worst part of today.  When you turn in your work, either cite your source or explain your logic.

Then imagine that you are going to take refuge on your roof from the ever rising tide of snow (remember it never stops falling).  How long will you have before the snow is so deep all around you that even when reaching your hand straight up, it doesn't reach out of the snow.  Assume, to keep the math easy, that the snow gathering on your roof slides down to match the snow building on the ground around your house so that when it does finally stop there aren't little mounds at each house, just a big open expanse of snow.

Otherwise enjoy the extra day of vacation!

SNOW DAY!

Enjoy kids!

BA Grades - How they are figured

So you've checked Skyward and you see a total of 8 grades listed in skyward for the chapter 6 test.  One says "Raw Score" and other 7 have various codes and descriptors.  Attached is a file that lists the objectives and shows example problems of each.

But what does it all mean?

Let's take Jenny.  She is a student who just took the test.  Mastery Manger, the software that grades the test tells me that she got 20 out of 25 questions correct.  That gives her a raw score of 80% or a B-.  That goes into the system as her Raw Score, or the first grade.

It also tells me that she "mastered" 5 out of the 7 objectives.  So in Skyward, each of those objectives will recieve a 1 or a 2 to show if she has been tested or if she has mastered it.  So her grades on the objectives might look like this:  A E A A A A A E, 5 A's and 2 E's.

This averages out to 71 % or a C.

Because of how the grades are weighted in Skyward, the Objective Grade and the Raw Grade are averaged together equally.  Jenny's achievement on this test would be, overall, a 75% or a solid C.  Not bad but not as good as she hoped.

For the math minded:

The weights on the test are 4.45 for the Raw score (which is actually out of 22 points) and 7.14 for each specific objective (out of 2 points).

So for the raw score, 22 * 4.45 puts it at 99.88 points.
For each objective, 2 * 7.14 = 14.28 each * 7 objectives = 99.96 points.
That makes the test a total of 200 points, equally split between raw and objectives.

What if we aren't happy?

Students can retest to show mastery of those missed objectives by providing evidence of improvement (generally additional practice) and then retaking the exam.  Missed objectives can be made up this way but the raw score does not change.

Why aren't other teachers doing this?

I am personally piloting this system of reporting this year to see if this specific level of feedback is useful or meaningful to students and parents.

{Geo B} / {Geo Ess} Extra Credit

In honor of our snow day today here is a chance to not miss out on this opportunity to flex the mathematical brain:

Objective:  How many snow men worth of snow is in your yard?

Assumption:
A typical snowman is made up of 3 spheres.  The radii of the spheres are 4, 2, and 1 foot respectively.

Question 1:  How many cubic feet of snow make up a typical snowman?

Question 2:  How deep is the snow in your yard?

To answer this, take at least 4 measurements and average them.

Question 3:  What is the area of your yard?

To answer this, include how you measured the dimensions. 

Question 4:  What is the volume of the snow in your yard?

Question 5:  How many snowmen is that?

Have fun playing in the snow folks!

{Geo B} Weekly Update

I know it has been a great point of stress this week so I want to apologize for my tardy update.  I have lost count of the emails pouring in to tell me what a great resource this has been and so I know exactly how many of you were probably noticing countless new grey hairs from the anxiety of not knowing this week's plans.

Joking asside, this week has it's ups and downs.  Monday was the BA exam.  Some students were able to complete it but a few bled into 3rd period.  Fortunately 7th hour on Tuesday did not have that time restriction but as a result we lost some class time into finishing up and did not get through much content.

Grades for the BA will be posted before holiday break.

This week it is my hope to get through 7-2 before the end of the week but I have a feeling Mother Nature, Father Winter, Cousin Bear of the Snow or who ever is in charge of that 12" of white stuff I had to shovel is going to interfere with this process.

I lied.  I have a snow blower.

{E2020} Weekly Update

Some thoughts specifically targeted to the group of students assigned to work 6th hour on their online classes:

1)  Your course progress is calculated with the assumption that you will be working over the holiday break next week.  That means that if you are caught up now, and you do not log in during the vacation, you ~will~ be behind.

2)  From here on out I will be recording your "Actual Grade" in the class every week in Skyward.  For those not familar, here is how it is computed:

First they compare where your student is in the course and where they "should be".  Every assignment that they are behind is assigned a grade of a zero.  If a student is caught up or ahead, then there are no zeroes to record.  The grade is then calculated based on the average of all grades.

So, if they are behind a few assignments their "Overall Grade" may be a B but because of those zeroes it shows as a C.  Likewise if they are ahead, then their Overal and Actual grades will be the same.  If you are unsure you can ask your student to log in for you and you can see their progress in the class for yourself, along with grades.

Also as a reminder, notebooks are required for me to approve them for tests, and there are ~no~ retakes of quizzes unless I have evidence that the system glitched while they were testing.

{Geo B} Reminder!

The Chapter 6 BA test is on Monday.

Students should review the packet from class (posted in Skyward) as well as all the assignments to date.  Also students may check the document attached to the test itself as it contains a breakdown of the 7 objectives they will be tested on and provides examples of each.

Could this be your student?

From class today:

Me:  If I take the time to write on the worksheet "Show the work for problems 3 and 4 on a seperate peice of paper", it is because I expect you to put the work for those on a seperate piece of paper.  In the future, if you don't, I won't grade it.  I'll take it to the office, shred it, and when you walk in, throw up in the air an shout "Look!  It's snowing!"

Student:  At least it's not a W.I.N.

The reality:

I expect students to show work for problems when they do their homework.  This work is essential for two things:
1)  To help them organize their thoughts and track their own understanding of the material.
2)  To help me review their work and identify weaknesses that we can together target for success.

I made a commitment in Septemeber to never assign more work then I felt was nessecary to arrive at mastery.  Every problem I assign, be it in classwork or homework, is targeted specificaly at skills students need to practice.  To that end I do expect students to complete every problem ~to the best of their abilty~.

So as I am collecting and reviewing all homework I will be looking at their work and I will not be grading incomplete papers. 

I will also not comment on students who attempt to turn in work totally unrelated to the assignment in an attempt to bamboozle me into thinking that they have actually done the assignment.  I do not believe comment is needed.

Hope you all have a great weekend.  Go Saints!

{Geo Essentials} Weekly Update

This week we've got some real creative opportunities for students:

Due Wed (4th hr) or Thrus (3rd hr) is the School House Rock song that helps students remember the relationships between the various quadrilaterals.

On Friday we'll be doing an art based project to explore the concept of Similarity.  Students will need to bring a picture from the comics about 2 inches by 2 inches in size.  We'll be then drawing a similar picture using the rules of Similarity covered in chapter 7.

{Geo B} Weekly Update

We're at February finally and things are starting to shape up.  This week's highlights include:
  • Quiz on Monday (2nd hr) or Tuesday (7th hr).
  • BA Reviews will be passed out on Wed (both classes)
  • We need to finish chapter 6 which includes talking about:
    • Coordinate Geometry Proofs
    • Trapezoids (and their Isoceles cousins)
    • Kites (as in Let's Go Fly...)
Remember that next week Monday (2/8 for 2nd) or Tuesday (2/9 for 7th) is our BA test on Chapter 6.  If you look in skyward you 'll see that there are listed the 7 Objectives students need to master to get 100% on that test.  With them is also a collection of example problems for each objective.

Speaking of, kudos to two students who were absent last week, went to Skyward, printed the worksheets and turned them in today.  Good initiative guys!
