AREA: Sensorial

MATERIALS: a wooden box with hinged sides and a top that lifts off. Inside the box are 8 pieces, 6 rectangular prisms and 2 cubes. When assembled, the pieces form one large cube in which each component represent a term in the (a + b)3 expansion

AIMS: DEVELOPMENTAL:

1. To observe, compare, contrast, discriminate, reason, decide, solve problems, make judgments, create order and appreciate the world

2. Sequential quantity

PRACTICAL:

To place cubes and prisms correctly back in box, to experience the binominal/ trinomial equation

PREPARATION: Monomial cube

AGE: 3-3 1/2 years

PRESENTATION BY THE TEACHER

THE MONTESSORI LESSON:

1. Invite the child to come and work with you. Show him the Binomial box and tell him the name.

2. ask the child to bring a rug

3. Put the lid on the left bottom corner of the rug

4. Take out all the cubes and prisms within CRO.

5. Sort all the cubes by colors, say to the child,“ I am looking for the largest red cube/ blue cube”

6. Bring the lid over to the middle of the rug to the right bottom of the box

7. Use your DH swipe the red square on the lid and say to the child,“ we always start with the red cube”

8. Use your DH point to the red square and then use your SD hand retrieve the red cube

9. Use your DH point to the red side of the cube and then point to the red square which will be touched

10. Put the red cube on the red square of the lid

11. remember to put all the cubes back in counter-clockwise direction

12. Use your DH swipe the red and black surface and then point to the black surface of the square

13. Use your SD hand pick up and retrieve the cube and then use DH point to the red surface of the cube on the cube and point to the corresponding red surface of the lid. Repeat point in the same way to the black side of the cube

14. Put the black and red cube on the lid

15. Use the same method finish the first layer and replace the first layer
