### Teaching Montessori Fraction Skittles with LEGO

AGE: 4 years

OBJECTIVE(S):
1. To introduce the concept of fractions.
2. To demonstrate how a whole may be divided into parts.
MATERIALS:
1. 4 sets of LEGO bricks (1 LEGO brick is a whole, 1 is divided into halves, 1 is divided into fourths, 1 is divided into eighths)
2. 1 worksheet with the following written: 1 whole, 1/2 (一半), 1/4 (四分之一) and 1/8 (八分之一)
3. 1 butter knife
4. 1 tray
PRESENTATION:
1. Take the whole LEGO brick and run both hands down the sides from top to bottom to feel that is whole. Allow the child to feel the LEGO brick.
2. Say "This is whole" and hand it to the child again.
3. Take a set of two halves of LEGO bricks, placing them side by side with the red surface facing you. Run your index finger down the two flat sides, picking each one up one at a time, and say, "This is one half."
4. Allow the child to feel the LEGO brick.
5. Take the fourths in the same manner, saying, “This is one fourth".
6. Take the eights and say, "This is one eight."
7. Give three period lesson to find if the child has the concept.
EXERCISE:
1. Take out the LEGO bricks the same way and have the child name them. Ask "Do you think the halves are same as the whole?" Compare and interrelate all of the skittles.
2. Mix them and ask your child to sort them back. Could be done with blindfold.
VIDEO DEMONSTRATION:

This is similar to the Montessori Fraction Skittles lesson plan. We tried this on 27 December 2015 (6Y8M22D). J understood this basic lesson, but was challenged when I tried to change it to a different whole number. He got a little confused when we did addition fraction. I will repeat this basic lesson for a few times, before we move on.

1. Take the whole LEGO brick and run both hands down the sides from top to bottom to feel that is whole. Allow the child to feel the LEGO brick.
