Use This to Build a Foundation with Decimals

After trudging through decimal teaching the last two years, I decided that students needed a stronger visual to help them see the patterns within decimal numbers…after all when students count to 20 in kindergarten, we have pictures of 1-20 plastered everywhere with visual models for students to see.  Because students need to see a longer set of decimal numbers to see patterns, I created this decimal number line (and a few other items).  The number line has numbers from 0.001-1 on it counting by thousandths.  On numbers where the zeros occur at the end of the decimal number the zeros are printed very lightly to remind students that these do not change the value of the decimal number and can be left off.  There are picture and number representations of each decimal and optional word cards that can be added by the teacher with the students through class discussion.

Sooooo Cute Spring Bulletin Boards!

Each year a pair of teachers are assigned a month to do the cafeteria bulletin boards.  We were given April.  With all the pressure of upcoming testing and the additional stressor of losing time to snow days, I didn’t have much creativity roaming in my brain.   This board started out as me just wanting to make a simple spring flower to cover up lots of space fast and then…  the board looked empty so I decided I must add a little lady bug.  I made the flower petals from bulletin board paper folded over and over before I cut similar to when making a paper fan.  This helped me not have to cut out a LOT of different petals separately.  Then the flower and lady bug idea kept growing and growing and growing…

We have an upcoming science fair so we decided to tie in a science theme along with the spring theme.  We made a larger lady bug with an investigating magnifying glass over the top for the second bulletin board.  A hula hoop wrapped in black paper strips was used to make the magnifying glass.  Then laminating film was stretched over the magnifying glass to look similar to glass.  Rolled up black bulletin board paper was used to create the handle for the magnifying glass.

We have gotten so many compliments on these boards about how they brighten up the room.  These are on either side of the stage in our cafeteria.  I hope these help spark an idea for your spring bulletin boards too!

Teacher “Happy” Freebie before Teasting

The weeks that precede testing tend to be the most stressful at school for teachers.  Because I see the frantic looks everywhere, I thought I would put a little cheer in everyone’s mailbox.  I put one little “happy” in each teacher’s mailbox during the middle of the weeks before testing.  One of the teachers called them “little happies” so now that is what they are!

In case you want to cheer some teachers nearby…I am providing the documents I used.  They are editable so you can change the wording a bit if you want!  Just click on the link below the pictures to download the file.

 

What NOT to Do with Dry Erase Markers!

Ya’ll are going to love this one!!  Just when the custodian was fussing about the painters tape on the floor and my door being open…I did a doozy….

Since I have been working with lots of intervention groups, I am trying to teach them concepts in a short amount of time while I have them out of the classroom.  Yesterday I thought I would work on some measurement estimation.  I gave the students 3 choices to estimate the length of a car.  12 inches, 12 feet, and 12 yards.  Since these students don’t have a lot of experience with measurement, I had many students say 12 inches or 12 yards so….

I saw the need to draw on the floor with a dry erase marker of course!  I drew a 12 inch line with a ruler, a 12 foot line with 12 rulers, and a 12 yard line with yard sticks so students could see the difference.  They were easily able to see that the 12 foot line was the best estimate.

Then it came time to rub the line off the floor and whadaya know…but…you guessed it…the dry erase marker wouldn’t budge off the floor!  AAAAAAAAHHHHHHH!  Oh, no!  Well, after soliciting some help
someone suggested dry erase board cleaner…and it worked! YAY!

Now if I had it to do over, I would still write on the floor because it didn’t take too much elbow grease to rub off–and the floor is like a new giant white board with endless possibilities!

 

Painter’s Tape Strikes Again…

In all honesty my goal was to really use painter’s tape on the floor to make polygons in the first place, but I took a detour with painters tape on this geometry.  I just love the fact that floor tiles are actually a square foot– so with that in mind,  I had to stick a little area and perimeter lesson down on the floor.

Polygons-1

Where did I stick the shapes?

You guessed it!  Near the bathroom of course!  After all, what other location in the entire school gets more visibility than the bathroom!

Polygons-2

Polygons-3

For the triangle and octagon I wrote inch measurements on the diagonal lines to help the students calculate the perimeter without a measurement tool.  You can’t see that in the pictures.

Polygons-4

I numbered the shapes so that they could be matched to an answer key.  I was trying to leave in a hurry so I didn’t quite get finished with the answer key.  That will be coming soon.

Polygons-1-2

Now, I did think to ask one of the evening custodians if this would be a problem, but she didn’t think so.  Well, the next morning, I got a “hmmmph!”  The day custodian immediately let me know that the tape had already come off of the floor a bit and asked me how long it would be there.

I said, “not long,” with a smirk.

He informed me that we had gotten second place for the cleanest school last year and showed me his plaque.

I said, “Well, we’ll be the most mathematical school.”

I’m leaving the tape down for a good 4 weeks ;D.

 

Do You Need Some More Math Activities for Math Night?

Take a look at these exciting photos of our recent Family Math Night.  Originally we had scheduled Family Math Night on the 100th Day of school to build more momentum for the event, but we had to reschedule Math Night due to weather.  I’m mainly including activities that we hadn’t done before, and I will include links to former math nights so you can get even MORE ideas!

To start, tables with parent information were set up in the hallway.  The more inviting and fun student tables were set up inside the cafeteria.

Since many parents are unfamiliar with ten frames (I had never heard of them until I had started teaching), we had a table informing them of how ten frames work.

MathNight2014Blog-32

 

Then we had an information table showing the parents of 2nd and 3rd graders addition and subtraction strategies.  Parents even had an opportunity to see how base ten blocks were used to do regrouping.

Here is a station explaining to parents how Reflex Math works.  We had a laptop set up to show parents Reflex Math from a kid’s perspective.MathNight2014Blog-43

One teacher put together game packets for parents to play math games with their children at home.

MathNight2014Blog-35

 

Now it’s time for the fun stuff!

Below you will see beach balls with math facts written all over them using Sharpie permanent markers.  When someone catches the ball, the right thumb’s landing spot determines the math fact that must be answered.   We had large beach balls for the kids to play with and small ones for them to take home.  We ordered the beach balls from Oriental Trading Company.

How many books will it take for YOU to weigh 100 pounds?  That is the question that students had to answer when they stopped at this station.  Students estimated how many heavy encyclopedias it would take for them to weigh 100 pounds.  Having experiences with measurement is the best way for students to make reasonable estimates with measurement.

Uh-oh!  Looks like he picked up too many books, but he’s close!

Fractions beckoned to students’ interests under the guise of a messy pudding party.  Students had to measure out two cups of milk without using a 1 cup measuring cup.  They had to use ½, ⅓, or ¼  measuring cup .  Doing so made them repeat these measurements until they had milk equivalent to 2 cups.MathNight2014Blog-4

What is Math Night without estimation stations?

MathNight2014Blog-10

I have done estimation stations every year we have had Math Night, but I wanted to do a little something different this year.

MathNight2014Blog-8 copy

Instead of just having the estimation jar, ziploc baggies were placed in front of the jars with 10 of the candy item inside.  This helped students make more precise estimates.  I also had a wild idea about gluing base ten blocks together to see who could come the closest to estimating the total of the blocks in a base ten tower.

MathNight2014Blog-29

How many are in this base ten structure?  Can you guess?

(above) I know the tower looks more like the leaning tower of Pisa than anything of mathematical value–it looks like a hot mess–a hot glue gun mess ;) .   What can I say…I think I should pose like one of Charlie’s Angels with my hot glue gun!

(below) Making 10 groups of 10 was a kid favorite last year and remained a kid favorite this year.  Kids took small food items and grouped them on a mat.  They got to eat their 10 groups of 10/100 items when they had filled up their mat! Yummy!

(below) Where did Freddy the Frog land on the hundred’s chart?  These kids played Toss and Guess, a game with a giant hundreds chart grid and a beanbag–in this case a bean bag frog.  The idea for the grid and the Toss and Guess game came from The Learning Carpet.  Kids received prizes when they guessed where the frog landed correctly.

MathNight2014Blog-51

Below is my absolute favorite booth of all booths!  How many hulas can you hoop?  Students hula hooped until they could hula no more.  Then they counted their hulas and wrote the total of their hulas on a piece of paper.   They stuck this paper to the wall so other students could compete with the highest total.  The two hula hoopers with the greatest number of hulas won a hula hoop!

The following made the evening worth while.  This parent solved math problems with her Pre-K student.  She helped him count on her fingers!  This embodied the goal of the whole evening–helping parents connect to their children through mathematical thinking!

Angles in the Bathroom?

In response to the poor scores on a recent geometry quiz, I took advantage of the prime real estate near the bathrooms.  Students in this particular class pass this area often, so why not put some geometry review in their path?  I made good use of a roll of painter’s tape by making types of lines and angles all around the bathroom entrances and water fountains.

The yellow sign below says to identify the figures and tells students to check the answer key to see if they are correct.

Then in an easily accessible place outside of the bathroom, I placed an answer key for students to check themselvesAnswerKeyCover

Underneath the cover are the answers…

I had more types of lines posted than are pictured above, but I thought a few of the pictures would give you the idea.  I’ve already seen kids looking to check their work on their way down the hallway.  :)

If you remember from one of my previous posts, then you will remember I have a weighing station outside the bathroom.  I also have a location for students to measure their own height with a measuring tape.  I still see students stop by occasionally to measure themselves.  I had one with a sideways grin tell me today, “I’m 47 inches.”

I hope this inspires you to do something similar with your students!
