Hi families,

I'm so sad this is my last week with the kids.  Telling them on Friday that I have to step down as their teacher was the HARDEST thing I have ever done and this has been the hardest decision I've ever had to make.  I told them today that we have to keep learning but we'll have fun and make memories along the way, most likely cry a little too.  Thank you to all the parents who have said kind and encouraging words to me about this terribly difficult decision I've had to make.  

As I said above, we won't stop learning this week!  Today the kids learned order of operations using PEMDAS and that will be part of their homework.  Take away the PE and you're left with MDAS for homework practice.  This means when solving a long problem the kids will solve multiplication and division first (moving left to right) followed by addition and subtraction (moving left to right).   Tomorrow we'll review in class for a test the kids will have on Wednesday.  Be looking for their chapter review for homework tomorrow.  This will be optional for them to complete but will REALLY help them be ready for the test.  We'll end our week on Thursday with a fun goodbye party. 

Thank you for all of your support and kind words.  Thank you for allowing me the opportunity to teach and love your child.

Hi families,

I decided I'm not a Broncos fan anymore after their AWFUL games these past two weeks!  Blah!  

This is a tentative schedule of what we'll cover in class:

Monday: Partial products 
Tuesday: No class due to field trips 
Wednesday: Mad Minutes multiplication tests and Chapter 2 mid-chapter test (No homework) Wednesday's math class is very short!
Thursday: Multiple strategies for multiplication 
Friday: Multi-step multiplication problems 

Expect to see homework Thursday and Friday if all goes well.  Homework was also sent home today. 

Have a great week.

Hi families, 

I hope you enjoyed the long break with your family.  Sadly, we didn't get any time off!  Oh well.  I loved meeting all of you during conferences!

This week we'll continue Chapter 2 which is all about multiplication.  This is a tentative schedule of what we'll cover in class:

Tuesday: rounding and finding reasonable answers 
Wednesday: exploring the distributive property
Thursday: multiply using expanded form
Friday: multiply using partial products 

Expect to see homework for most of the days this week and possibly over the weekend.  

Update on late work policy: 

  • Absentee make up:  Students are given two days per excused absence  to make up assignments. However, if the student was absent on a date when an assignment was due, it is expected that when the student returns to school, the assignment will be turned in the first day the student is back in class. It is the responsibility of the STUDENT to ask the teacher for the make-up work.

  • Late work policy:  Late work, up to four days late, will have points taken from the responsibility portion of the grade. 

The following late work policy will be used:

    • 1 day late = responsibility grade drops by 1 letter grade (A to B)
    • 2 days late = responsibility grade drops by 2 letter grades (A to C)
    • 3 days late = responsibility grade drops by 3 letter grades (A to D)
    • 4 + days late = responsibility grade will be a zero (0)

  • Assignments turned in later than 2 weeks:

    • Assignments will receive 50% credit in the standard and a zero in the responsibility

    • Copies will not be given after that time

Also, this has been stressed to the students multiple times: Any graded assignment without a name is displayed for the kids to see then docked two points from the final grade. Any homework turned in without a name is kept for one week then recycled. If a student thinks they turned it in, they can look through the no-name homeworks to see if it is there or the late work policy applies to any copies made and the late homework that is turned in. I will not display or go through missing homework with the kids; this is available on IC. I have so many things on my plate, I hope you understand the need for this policy.

Have a great week! Let's hope the Broncos show up to play this weekend!

Hi families,

Hope you've been doing great!  I've been SO BUSY I can hardly sleep at night, so I'm sorry for the lack of blogs lately.  As I said at curriculum night, I also am very fluid with my teaching so things I write in my blogs hardly ever 100% happen because I teach based on what happens each day in class.  Anywho, here's the flexible plan for this week:

Monday: review in class for the test!  I have a fun game planned for this.
Tuesday: Place value test (I've heard this will take multiple days to complete)
Wednesday: continue test
Thursday: multiplication pre-test and number tests 
Friday: start Chapter 2, multiplication 

Based on how the kids do on the place value test, I may do some reteaching of place value concepts on Thursday.  Also with the multiplication tests, I will see what the kids already know and plan the unit accordingly.  

Important Info:
  • The kids will have a few pages of review as homework on Monday and it will be due Wednesday.  That way the kids can use it to review/study Monday and Tuesday night. 
  • There likely won't be much homework this week due to all the tests I'll be giving. 
  • Conferences are next week; be looking your conference date and time in your child's planner this week.  Looking forward to seeing you!
  • The kids enjoyed their first class reward last week! =)
Have a great week!  Go Broncos!

Hi families!

Mondays are my MOST busy day of the week so you'll find that you receive a blog post either early on Sunday or late on Tuesday.  SO sorry!  I'm trying to manage Mondays better! =)

It was so great to see many of you on Thursday for curriculum night!  I may have dropped the ball when I didn't tell you that my class is a 4th grade GoMath! class.  We will be covering 4th grade Common Core State Standards this year.  I made the assumption that you already knew that, and I apologize for not being clear last week!!

I am still trying to get into the swing of things with the new GoMath! curriculum but things are slowly getting better!  I looked over their journals on Thursday and we worked on forms of numbers, comparisons, and ordering numbers based on place value, and the kids rocked all of it!  As I'm sure you've seen, I did send home two pages of homework on Friday that are due Tuesday this week because they did so well on Friday.  I think they are just getting use to the difference in how the workbooks are organized and the amount of word problems they have to do, which require multiple steps.  

I have gone through Chapter One and just so you know, most of what is in this chapter is review, however, just laid out and asked in a much different format than Singapore.  We will continue through the chapter to review and lay the foundation for what will come in this new curriculum.  Here is a brief plan for the week:
  • Rounding Numbers and mid-chapter assessment (will count as a quiz and show what they learned so far)
  • Renaming Numbers
  • Adding and Subtracting whole numbers 
  • Problem Solving 
I will be gone on Friday, so I'll leave fun games and activities for the kids to do to reinforce what we learned and help prepare them for the Chapter test I'll give next Tuesday.  

Just a Few Things...
  • We use whiteboards on a daily basis and sure could use some lonely (clean) socks for erasers!  If you have any, please send them our way!  TIA!  
  • For those of you who missed curriculum night,  here is a link to the Prezi I showed:
  • The online portion of GoMath! should be available for the kids on Tuesday!  Thanks to Kaia's mom, Jamie, for setting this up for us!!  Yay!  
  • Homework will continue to go home.  Since the kids have been able to get use to the format and amount of homework each page requires, I will be asking that they complete all of the homework.  The Spiral Review is often difficult but covers 3rd grade math standards which your child should know.  If it is too hard, please allow them to choose the ones they can easily complete on their own or with minimal support from you.  Please let me know if you have questions about homework. 
Hope you had a great weekend and watched the Broncos kick the socks off the Cowboys!  Woohoo!

Hi families!

I am so excited to be your child's math teacher!  I loved meeting them last Wednesday and can't wait to spend the year with them!  

Last week we played a fun name game then unfortunately went right into testing Thursday and Friday. =( Poor kids, but they worked hard and followed my expectations very well!  Tomorrow, a handful of kids will finish their test while the rest of the kids and I play a fun dice game.  The rest of the week will be fun community-building activities that teach a lot of my routines so the kids will have fun while learning!  The kids will also create a "Me in Numbers" display that you can check out on curriculum night, September 14th.  

I am looking forward to meeting many of you next week, however, feel free to stop by and introduce yourself during dismissal.  I'm always outside! =)  Have an awesome week!

So sorry for the late blog post, families!  My grading pile is sky high and never ending!?  

The poor kids have been testing since last Thursday!  First my test then we got both the GoMath and Singapore tests, too!  Every day since Friday I've said "Sorry kiddos, another test."  They are tested out, to say the least!!  My test counts for a large grade, however both the GoMath and Singapore test do NOT count for any grade.  GoMath is to help for placement for next year's math class and Singapore is just data, nothing more.  The only test you'll see coming home is my test.  I'll show the kids them tomorrow (I'm soooooo proud of them!!  Awesome grades!!!) then be looking for them in their portfolios tomorrow.  Speaking of portfolios, I wasn't on top of that this year (my secret passion project was surviving my first year at Stargate) so I sent home almost everything the kids did in Monday folders, so you won't see much tomorrow.  

Tomorrow is sadly our last day. =( I bought popsicles for the kids and we'll play games and just enjoy our last day together.  Thank you for a fabulous year and have a great summer!!

Hi families!

Only two weeks of school left!?!  What?!  This year has flown by.  I'll be so sad to see the kids go soon. 

Since PARCC testing, we've covered a lot of different concepts and I'd like to assess the kids on what they learned since then so I'll be giving their final test this week.  We will review area, perimeter, decimals, and measurement both Monday and Tuesday and our test will be on Thursday.  If the kids need more time, I'll give them Friday as well.  I'll be sending home a review sheet for homework tomorrow that will help with getting ready for our test.  I have anchor charts in my classroom for help during the test and the kids can use their measurement conversion sheets and multiplication charts as well.  I am confident that the kids will do well.  Wednesday is Field Day, so no math but the kids will still have to be ready for the test on Thursday.

Other great ways to study are Prodigy (all the questions align with the test questions) and the kids can replay the jeopardy game we are playing tomorrow.  It's on Flipquiz and the link is

I've also attached the review sheet to this blog.  If you have any questions or concerns, please don't hesitate to ask!  Thanks for a great year; I have truly loved spending my days with your kids.

Hi families!

Where has this year gone?!  Only four weeks of school left; I can't believe it!  We have another short, silly week so not much happening again. =/

I sent an email out about Fruit by the Foot measuring tomorrow; if we get enough then we'll have fun measuring in centimeters, inches, and feet tomorrow!  Tuesday is all day theme or a field trip so no Math. =( Wednesday will be working on equivalent fractions for other units of measurements such as cups to gallons, ounces to pounds, etc.  Their homework tomorrow will reflect this and is due Wednesday.  

Thursday is an assessment day for Literacy and no school Friday, so that's it for this week!?  I sure hope we can get some time to teach and learn soon!  Hope you're having a fabulous day and have a great week!

Hi families!

So sorry for the late blog post.  This week is complicated, but what's new?!  We didn't have math yesterday.  Today the kids finished up some decimal art work they started last week and enjoyed an extra recess they earned.  Tomorrow and Thursday I'll go over units of measurement and equivalent measurements.  Homework will reflect this.  The kids will have MAPS testing on Friday so no class work for that day.  

Hope you have a great week!
