box of bobbins and the concept of zero box spindles
Material
45 spindles in a box or cup
8 elastic
two boxes divided into 5 compartments each, each compartment being numbered from 0 to 9.
Manufacturing
boxes can do so even if you master the art of cardboard. The spindles can be chopsticks or Chinese journals purchased hardware store and then cut and sanded. One can also use empty toilet paper rolls glued together and numbered from 0 to 9.
prerequisite
The child needs to know numbers and associated bar Digital (red and blue bars).
Objectives
The child can associate the quantities already put together and their symbols with bars mathematics (red and blue bars). In this exercise, the symbols are fixed as determined by the trap boxes. These are the quantities that the child will have to create and associate the symbol. He will also discover the meaning of zero.
Presentation
The Guide read the numbers on the box of time to the child.
Then he points a finger and with a bed. It takes a time, puts it in his hand and said, "1". He puts the time in box 1.
Then he points his finger and 2 with 2 bed. It takes a time and puts his hand in a spot, he took another, poses in her hand and said, 2. It takes an elastic band and breaks out each gesture to show the child how to put the elastic around the spindles. It sets the time and put together in the locker two. It continues until 10, leaving the child do when he has understood and shows the desire (usually around 4 or 5).
In the end, there is nothing left in the box spindles. The guide points the finger at the empty box. Then he said to the child: "Now we'll read the whole story," a mysterious air. He points the finger on the 0, known as "zero" point the finger at the empty silence. Then it goes to 1, the peak symbol and said one takes the time, and submit an account in the box. Then it points to 2, said two, take the time, removes the rubber band, has two and give the time in their box. So on until 9.
Notes
Using elastic problem at first. We must break down the action so that the child takes ownership and do not try to ignore the elastic. 5 this is not a sparse amount of 1. But it all makes 5. Symbolically, it is important to set the time.
I also do not explain the zero. Some do when they read the story, saying "zero is nothing." I'd rather not say. The child will find out for himself and say when he will understand the concept of zero. For that I am a little game
Game Zero
The guide offers the child a game, it asks him to fetch four nuts in the house. Then a Christmas ball (because it is the period but this may be something else), 8 pens, 3 clementines ..... And 0 turd in chocolate!
The issue is: has he noticed that there was nothing in the case 0 the box of time?
If yes, there will stunned and go through a whole range of feelings (Astonishment, frustration, thin I will have eaten well at least me a turd in chocolate, laughing .....)
If not he will return perhaps. No, I asked 0 turd in chocolate. Insite until he understands that he must not return because 0 is nothing really and if all else fails, take the time several times before the game repropose zero. But please do not say anything! Show the empty box and read the number 0 without adding anything. I'm not ready to forget the looks on my kids when they discovered that bin zero is nothing ....
can also ask him to 0 kiss.
Or allow him to eat cake 0.
Or ask him how he crocodile in his pocket? ...... zero.
From 0 to ball in a box ......
Finally, discuss the concept of zero: in fact, what is zero, according to you?
Repeat play time. Ask the child why there is no time to square one. If realized, it will tell you: 0 is nothing, so it does not have time (or it does nothing).
In the days that follow, I am much amused to make "jokes" with this zero, without hesitating to go into the wild. And Luan did not lose me do in return. "Mom, you can give me zero pants this morning?" I do not want to get dressed! "
beads in the box with the smallest to the largest, forming a nice triangle colored. Then he puts labels by placing them in the order of 1 to 10.
