Ten frames are an important math tool in many pre-school, kindergarten, and first grade classrooms.

So, we include it in our calendar time. (We actually call it "together time", since we are together, and do all sorts of things ... I like to leave things open ended.)



We know that a solid understanding of how "ten" can be taken apart and put together is crucial for successful future math learning.

For years I tried  different Christmas countdowns - Santa's beard cotton balls, daily cutting off a slice of Santa's beard, paper chains  - but none of them seemed to work for me. 

A few years ago, I hybridized (is that a word) a couple of seasonal crafts - a decorated cone tree and a painted paper plate tree

Add in some numbers and stickers - and I had a December project that I not only could manage - but the kids and I both enjoyed.


First step is to paint paper plate green. I find that the best ones, are the super cheap, will barely hold potato chips paper plates. 


I cut the plates into 3 triangles and glued them together to make a tree shape. If I was not madly painting and prepping in the last days of November, the kids could do these steps. 


When I first did this project with the kids, I did it as a countdown - if we had 15 days of school in December, I put numbers 1-15 on the tree.


The last couple of years, I have changed it up a bit. I printed the dates in December we would be in school. This year, we were in class December 1-4, 7-11 and 14-18.  I  put the dates on the trees randomly and in different places on each tree so that the children had to find the number, not just see where their classmates had found it. Except for the last day in school - that always goes at the top. 


In addition to number recognition, the kids were interacting with a calendar and seeing how it worked. 

Each day the kids add one sticky shape


I have chosen to use shapes stickers for the kids to cover the numbers - they are bright, colourful, but not associated with any holiday. The last number is different - that one gets a star (if the children want).

The kidlets will take home a beautifully decorated tree on the last day of school before the holidays. (And they have used number recognition and  numerical order skills, and have interacted with a calendar.)

No cotton balls. No loops. Minimal prep.  The kidlets like it.

I am a happy teacher.


             
            

How many pumpkins tall are you?

Today we measured in pumpkins.


Yup, orange, round things, grow on a vine, used to make jack-o-lanterns.

What are we learning?
numeral recognition
numeral printing
counting
counting by 5s
counting on
non-standard measurement 
(a first step in learning measurement before using standard measurement tools)


First the kidlets measured themselves on the pumpkin measuring chart.  


Our very tall principal even got in on the measuring fun!

Each child recorded their pumpkin height.

In the afternoon we measured with pumpkin measuring sticks.


Sometimes I put out a bunch of random objects from the classroom  for the kids to measure. 

Sometimes they explore the classroom to find things that they are curious to measure. 

Usually we find a "big" project that we need to work together to measure. Today I was the big project! Sadly (not really!!) there are no photos to share of that measurement experience!

Print, laminate and measure.



        



Out to the forest we went, ten groups, two by two, paper bags in hand.



Instructions were to work together to collect 10 items found in the forest - they could not choose 10 of the same thing. (We did not want 100 pinecones!)
The kids have been busy making patterns, seeing connections, playing with geometry, using their fine motor skills, co-operating and being creative this week.

Our heart geoboard was a popular spot.


Last year I took the plunge and changed the way that we "do" calendar. (Thanks to (Matt Gomez and Mardelle Sauerborn who posted about their calendar journey.)

Instead of the traditional turn-the-date-over monthly calendar, I  put up all 12 months,  to create a living document of our year.


It was a learning curve as the kids and I figured out together how we wanted it to work. 

First thing that went up was all the birthdays.  Pretty important.

my goals 
I wanted the kids to see the passage of time.  The whole school year - not just the current month.   
I wanted to the kids to refer to the class calendar the way that I use my calendar at home - to see when events were going to occur.
We are in the middle of planting seeds and growing thing.

And my student teacher, Miss Jane, decides that seeds are not just for planting - they are for measuring.


We had such wonderful weather that we just couldn't stay inside.  So we didn't!

Time for a little numbers and counting practice - outside.


Circles and rectangles make fine looking winter trees.


Oliver Jeffers, with the help of the Hueys, is answering the question, "is none a number?"

numbers, counting, math

As well as hiding chocolate, (and all the other wonderful uses), plastic Easter eggs are great for practicing number sense.



100 days of kindergarten is worthy of celebration.

So, we celebrate.


Big time.  Because I00 is a pretty big number.


One of the 100 Day traditions is the 100 penny hunt.




Somehow, I suspect it is Zero the Hero, 100 pennies get hidden in the classroom.  (Yes, Canada phased out the penny last year, but we have "leftovers" from our penny counter project - and if desperate, I can always head south of the border into Washington State).


The pennies are hidden ...


The penny chart is ready - taped to the table.




And the hunt is on.


The rule is that after a child finds ONE penny, the penny is to be brought to the chart and filled up from number 1.




The kids were expert penny finders.




In no time (it seemed), they had found all 100 pennies. (One year they managed to find 102!)


Next time, I think I will use a stopwatch to time the hunt.  How many seconds does it take a kindergarten class to find 100 pennies?

Enjoy a song about 1000 pennies by Norman Foote from his cd 1000 Pennies!  







            

We don't need an excuse to make cookies.

We do need a reason to make 100 cookies.

100 Day is a good reason to make 100 cookies.

We figured out that  20 kids each had to make 5 cookies.

And we set to work. 

3.14

The kids have been measuring everything they can with measuring tapes.

We discovered that it is really hard to measure around the edge of a circle.

Luckily a few thousand years ago, some mathemagicians figured out that if you measure a circle at the biggest part (the diameter) and "times it" by 3.14, then you know the circumference. 

They called this special number pi. 
And their alphabet did not look like ours; pi looked like 


The kids thought that was pretty  interesting.  They thought it was neat that mathemagicians have their own secret math code.

I told them that today was Pi Day.  3.14  We counted that March is month number three.  And that is is the 14th day of the month.  3.14.  That made sense.

Then I really got their attention.

What does the word pi sound like.  Hmmmm.  Pie?

How do you think we could celebrate Pi Day.  Pie did seem like  good idea.

The kids could choose either apple or blueberry pie.  And three choose apple-blueberry.


Into the oven.

Out of the oven.


Into the tummy.


Even pie measuring.  It was also noted that the diameter of the pie was "fatter" than the diameter of the muffin tin opening.  


I am thoroughly convinced that my kidlets are brilliant.  Even so, I decided against telling them that pi is an eternal and irrational number.  I need to leave something for their high school math teachers!

Check out this pi domino spiral.  The clip is 3.14 minutes!

                             

maybe I'm finding my inner math geek
