Mindfulness, Math, and Mallards

Our family meeting focus this week has been to exhibit mindfulness.  Ask your child how being mindful can help them deal with stress, ignore false alarms to the amygdala, be a better community member, and be more adventurous!  Check out these young mallards participating in a mindfulness sort!

    

We have also rounded off our study of graphs and line plots (for now) and have begun talking about the four forms of place value.  Can you child tell you about those four forms for three, four, five, and six digit numbers? (standard form, word form, model form, and expanded form)  We’ve added in quite a few place values this week, so it’ll take plenty of practice before it’s “easy!”

            

Do you know how to predict?  We certainly do!  We have learned that predicting is not just guessing what will happen next in a story or text, but it’s also about having evidence or proof from the pictures, text, or personal connections to make a smart prediction.  We have also talked about how predictions may not come true, even though we have proof, so then we have to revise our prediction!  Ask your child to tell you about all the books we predicted with this week.

Lastly, have you seen the Mallard on campus?  We will have the chance to name him this year.  What kind of creative names can you come up with?

Your children are such wonderful little people, and I’m thrilled to spend seven hours a day with them!

Day 2 in room 36

Yesterday we survived; today we dug in!  We learned all about our brains and how they react to danger, aced a spelling assessment, and designed a survey to learn more about our peers.  We also snuck in a few minutes of REAL reading around the room.  Enjoy some snapshots from our day!

Making a budget…

Tomorrow and next week, we will be talking about what it means to make choices with our money.  Because we can’t have everything we want and need, we have to make smart choices with our money.  The choice we make is our economic choice.  What we give up when we make that economic choice is our opportunity cost.  Talk to your children about what kind of choices you have to make when you are going to the grocery store, gas station, mall, and anywhere you spend/save money!

ActivExpression

Have you ever laid eyes on one of these?  These are cool phenomenal capital resources called “ActivExpressions.”  They are used to interact with flipcharts, powerpoints, or anything on our great Promethean board.  We have mostly been learning to use them to practice in math, until today.  Today, we took our Wordly Wise quiz right on these bad boys!  Here’s how it worked: we took the quiz on paper, then entered our data into the ActivExpression, and sent the data to Ms. Beck’s grade book.  I bet you didn’t have anything like this when you were in school, huh?  Technology is amazing!

Animal Project Fair

WOW!  These third graders created some phenomenal projects!  After months of research and project creation, we had our class fair and I would say it was a success!  Here are the pictures!  Five friends have their projects displayed in the library for the next few weeks, and the rest are on display in our classroom until the end of next week!  They should be SO proud of themselves!


Mr. Fernald’s Math Challenge

Each week, Mr. Fernald puts up a math challenge for each grade level on the morning announcements.  Last week his problem was this:  Mr. Fernald measured his bookcase.  It was 48 inches long.  How many feet long was the bookshelf?

Check out all the different ways we figured out the answer!


Innovation Station, MSIC Field Trip

On Friday, we were able to take a trip to the Math Science Innovation Center (MSIC) to be innovators.  We used legos to build different machines and attach engines and different types of sensors.  Then we used a computer program to tell our machines what to do.  Once we knew our machines worked, Ms. Layne challenged our teams to create a Rube Goldberg machine where three machines work together to push a ball into a goal.  I have included a picture of a Rube Goldberg “Self-Operating Napkin” and a great video we watched about how they work.  What a great day!

Work It Out, Wednesday!

Each Wednesday, we start our math block by doing a challenge math problem.  Today the question was as follows:

Look at the following sequence: 1, 7, 13, 19, 25…. Is 80 a member of this sequence?  Explain your reasoning.

The students are expected to solve the given problem and then write a few sentences to explain what they did to solve the problem.  Here are a few pictures of your children in action!  Ask your child to talk through what they thought and what we found the answer to be!  We discovered that we were using place value, patterns, and 100s charts to figure out our answers!

What number is the greatest? Smallest?

It’s no secret we’ve been working on place value in math over the past few weeks.  Check out our fun day of reading and comparing six-digit numbers!  Ask your child to get out their math notebooks and show you how to play this weekend!

Rounding on a Number Line

This past week we have tackled rounding three digit numbers to the hundreds and tens place!  While tricks are quick and most of the time correct, being able to show where any given number falls on a number line is the best way to prove a deep understanding for what rounding is.  We also talk about the importance of understanding the value of the digits, and knowing that the 8 in 987 doesn’t mean 8…it means 8 groups of 10, or 80!

This next week, we will be looking at rounding numbers with 4-digits to the thousands, hundreds, and tens places. Get ready for some frustration!  The more practice we give them, the easier rounding will be.  Check out this picture of Trey working hard to use a number line to round!

Good looking – hard working.

Just take a look at these great students!


Place Value, Adding, Subtracting, and Kahn Academy

Mason Math

Here’s a picture of Mason demonstrating all four forms on his whiteboard!

There are four forms we focus on in third grade for 3, 4, 5, and 6 digit numbers.  They are as follows:

standard form: writing the numbers the way we are used to seeing them (843)

expanded form: showing how we add the values of each digit to create the number (800+40+3)

model form: demonstrating the number in pictures

Capture

 

 

 

 

 

 

word form: writing the number using words                 (eight hundred forty three)

 

When given any of these four forms, your child should be able to give you the other three!  Try it out using any three digit number.  To make it even more challenging, try leaving out a place value (390 or 501) and see how they respond!

We also spent quite a bit of time working on addition and subtraction with three digit numbers on Friday.  Many of my students would benefit from some new ways to see addition and subtraction.  Check out the two videos below!
Adding: why carrying works: Sometimes when we add, we carry our tens to the next column. Let’s watch this so we can understand why it works.


Subtracting with regrouping (borrowing): Learn how to subtract 23 from 65 by thinking about tens and ones.

I will also be exploring Kahn Academy with your children this year.  You may have already gotten an e-mail about it from the Kahn Academy website.  I will be able to differentiate your child’s math instruction a bit more through this use of this amazing resource!  Check it out!
