Fraction and division

Division

In our classroom, I let children try materials when they show interest.

Today, princess has interest on the long division material. Therefore, I use the material to introduce division. Well, princess only knows basic addition and subtraction and no knowledge of multiplication.   Instead of using the inverse of multiplication, we introduce ‘fair sharing’

Fair sharing – all beads are shared for all skittles and everyone should have the same amount of beads

To make it more interest, we pick one equation and play doctor game.

The question is 20 divided by 4

Princess is the doctor. There are 20 pills and 4 sick people. Doctor needs to distribute the pills to the patients.

In this case, each patient has 5 pills.

Doctor gives instruction that patients only take one pill per day, then princess said they need 5 days to finish all the pills.

 

Fraction

Fraction is a key learning chapter in Math.  In Canada, school introduce the concept of fraction in grade 3/4.  In our classroom, we introduction fraction in Pre-k / K.

That’s the first time princess do fraction skittles.  We talk about ‘whole’ and ‘part of whole’

With the color coded materials, princess matches the cards with skittles.

She is also interested on the fraction circle, so we make some fraction based on our fraction cards

 

 

 

With the fraction skittles, princess see 2 fourth skittles are equal to 1 halve skittle. That’s the magic of Montessori material. The materials are so well designed. Children get the math concept through the work.
