Exploring Dimensions with Sensorial Exercises

Exploring Dimensions: 

Exploring dimension is a basic division of Visual sense. In these exercises child can differentiate between objects which have similar shapes and color but different in length, width, height and thickness. Below are the few exercises:

1. The Cylinder Blocks	2. The Pink Tower	3. The Broad Stairs
4. The Long Rods	5. The knob less Cylinders

The Cylinder Blocks:

Materials: 

Four finely polished wooden blocks each having ten cylinders. Cylinders have knob to hold.

Block 1 Cylinders	Block 2 Cylinders	Block 3 Cylinders	Block 4 Cylinders
Vary in height, length  and diameter, 5.5cm to 1cm	Vary in height, length  and diameter by 1/2cm(5.5cm to 1cm)	Same height of 5.5cm	Same diameter of 2.5 or 3 cm
Largest one is tallest and thickest	Height increases by 0.5cm(from 1cm to 5.5cm)	Diameter decreases by 0.5cm(from 5.5cm to 1cm)	Height decreases by 0.5cm(from 5.5cm to 1cm)

       I.            Exercise: 

In this exercise directress guide the child how to hold the cylinder from the knob and then put it into the table. After bringing all the cylinders from Block 1 to the table, directress put each cylinder back into the block without making noise. Repeat this exercise with Block 2 and 3.When few children mastered in these three blocks after that Block 4 introduce.

    II.            Exercise: 

In this exercise directress guide the child how to use two blocks at a time. Mix cylinders and then put them back to their right position.

 III.            Exercise:

In this exercise directress guide the child how to use three blocks at a time while placing them in a triangular shape. Mix cylinders and then put them back to right position.

 IV.            Exercise: 

When child mastered with all three blocks then directress guide the child how to use all blocks at a time. Placed all blocks on table in shape of square. Mix the cylinders inside the square and then put them back into their right position.

The Pink Tower:

Materials:

Ten wooden cubes from the size of 1cubic centimeter to 1cubic decimeter. Cubes may be finely painted with pale pink or plain wooden finely lacquered. Strong pink color avoided.

       I.            Exercise:

In this exercise directress use table or mat for this, place all cubes on it. First hold the biggest cube with both hands compares with others and put it on the table. After that, take the second biggest cube compare with other cubes; put it carefully without any mistake on the middle of the first cube. Repeat it until all cubes finished and a tower build. Now place both hands on the sides of the tower, slowly move hands upward aside the tower, hands join each other at the top of the tower. When child mastered this exercise introduce him the second one.

    II.           
Exercise: 

In this exercise directress make the tower exactly the same way just like in exercise 1, but this time the cubes are placed on the one corner side of the previous one. This shows that one side of the tower is straight. The smallest cube first place at the top of the bottom cube and with the help of index finger pushed it to the top of tower. This helps the child to differentiate the sizes.

 III.            Exercise:

In this exercise directress make a tower horizontally on the table. Place the largest cube on the right hand side. Place the second cube very carefully in the center of the previous cube. Repeat it with all cubes.

The Broad Stairs:

Materials: Ten brown wooden prisms having same length of 20cm but vary in height and width from1 cm to 10 cm.

	Prism 1	Prism 2	Prism 3…………	Prism 10
Length	20 cm	20 cm	20 cm ………….	20 cm
Width	1 cm	2 cm	3 cm ……………	10 cm
Height	1 cm	2 cm	3 cm ……………	10 cm

       I.            Exercise: In this exercise directress use table or mat for this, place all prisms randomly on it. First hold the largest and thickest prism with both hands compares with others and put it on the table. After that, take the second largest and thickest prism compare with other prism; put it carefully without any mistake aside of first prism. No space between the prisms left, if there is space slightly pushed second one towards the first. Repeat it until all prisms finished and a horizontal stair build. Now pass hand over the stairs from biggest and thickest to the narrowest. When child mastered this exercise introduce him the second one.

    II.          

  Exercise: In this exercise directress build the stairs just like exercise 1 but for showing child the difference of the height of the smallest prism, she hold each step of the stair from index finger of both hands and slightly move it, then again place it to proper position.

The Long Rods:

Materials: Ten wooden rods usually painted red having height and width constant and length increased by 10cm, shortest have 10cm and longest one is 100cm.         

                                                      

I.                Exercise: In this exercise directress use mat for this, place all rods horizontally and randomly on it. First hold the smallest rod with both hands compares with others and put it on the left of the mat. After that, take the slightly longer rod compare with other rods; put it carefully without any mistake aside of first rod. Repeat it until all rods finished. The shortest rod near to the directress and the longest rod farthest on mat.

II.             Exercise: In this exercise directress arrange the rods as in exercise 1. Hold the smallest rod with the index finger of both hands and place it aside with other rods just to compare its length.

The Knob less Cylinders:

Materials: Four sets of wooden cylinders.

Yellow Cylinders Big-Small	Green Cylinders Deep-Shallow	Red Cylinders Thick-Thin	Blue Cylinders Tall-Short
Vary in height-diameter	Vary in height-diameter	Vary in diameter	Vary in height

I.                   Exercise: In this exercise directress use table or mat for this. First teach the child how to open the lid of the box of cylinders. Then place all cylinders randomly on table. First hold the largest cylinder with hand compares with others and put it on the center of the table. After that, take the slightly shortest cylinder compare with others; put it carefully without any mistake at the top of the first cylinder on the middle of it. Repeat it until all cylinders finished and tower build.

II.                Exercise: Directress may put cylinders in a row for grading them.

Extension Exercises with Pink Tower and Broad Stairs:

Materials: Pink Tower, Broad Stair, a Mat, a White Sheet (2.25 meter long and 1 meter wide)

I.                   Extension- Horizontal: Place Broad Stairs on the mat according to its exercise I. Then place Pink Tower cubes aside with the broad stairs prisms, as the largest cube with the largest and thickest prism. Continue until all cubes placed aside with the prism.

II.                Extension- Vertical: Take the thickest prism from the Broad Stairs and put it on the mat facing rectangular side to the directress. Then take the second thickest prism place it on the center of the first one. Continue until all prism sets vertically. Now take the largest cube of the Pink Tower and place it very carefully to the right square side of the thickest prism. Then take the second largest cube and put it on the first cube in such a way that its side attach with the square side of the prism. Continue until all cubes placed aside the prisms and build a tower.

III.             Extension- Monument: Place the Broad stairs just like Exercise I of it on the left side of the mat and Pink Tower cubes according to their grading horizontally on the right side.

First level: Take the thickest prism from the Broad Stairs and put it on the mat facing rectangular side to the directress. Now take the largest cube from the Pink Tower and placed it aside with the prism on its right side. Take the second thickest prism and placed it on a first cube. Half of the second prism comes to the first prism. Now take the second largest cube and put it aside with the second prism on to the first prism, a place which is left after placing the second prism. Continue until all prisms and cubes arranged and look like a wall.

Second level: Take away the smallest cube from the top of the wall and put it on the left side of the mat. Now hold the first top prism with finger and thumb and take away the second cube. After that hold the second top prism and carefully take away the third cube. Continue this procedure until all cubes take away one by one.

IV.             Extension- Shadow: Spread white sheet on the floor. Build a Pink Tower on the middle of the width of a sheet. Now take the thickest prism placed it aside with bottom cube attaching square sides. Then take the second thickest prism placed it next to the first prism making 90 degree angle with a pink tower. Continue until all prisms placed. Switch on the torch behind the Pink Tower and adjust the shadow equal to the Broad Stairs which is 2 meter in length. Now slightly move the beam of light to left to right and then backward. By this shadow move from right to left, left to right and passed over the stairs.

V.                Extension- Alternate: Take the thickest prism from the Broad Stairs and put it on the mat facing rectangular side to the directress. Then take the largest cube from the Pink Tower and placed it over the prism on the middle of it. Now take the second thickest prism and put it on the first cube in such a way that it balances and will not fall off. After that placed the second largest cube on the middle of second prism. Continue until all the prisms and cubes are assembled.

VI.             Extension- High Stairs: Take the thickest prism from the Broad Stairs and put it on the left side of the mat, resting its square side on mat. Then take the second thickest prism and placed it aside with first prism touching rectangular sides. Arrange the rest of the prisms in this way. Now take the largest cube and put it on the thickest prism. After that take the second largest cube and put it on the second thickest prism. Continue until all the cubes placed on prisms.

Extension Exercises with the Long Rods:

Materials: Long Rods, a Mat

I.                   Extension- Vertical: Place the rods randomly in a horizontal way on the mat. Take the longest rod and put it on the mat. Then take the second longest rod and put it on the top of first rod while their left edges even. Continue until all rods placed vertically.

II.                Extension- Maze: Place the rods randomly in a horizontal way on the mat. Take the largest rod and put it on the floor. Now take the second largest rod and put it on the floor at the 90 degree with the first rod and their ends meet. Continue with all rods making 90 degree with their previous rods and having a shape of a maze. Allow the child to walk in slowly in a maze and then comes outside without touching rods.

Extension Exercises with the Cylinder Blocks and Knob less Cylinders:

Materials: Cylinder Blocks, Knob less Cylinders, a Mat

I.                   Extension- Comparison: Place green set of a knob less cylinders horizontally on a mat from biggest to smallest. Then take the block cylinders and put it on the top of the knob less cylinders.

After that compare each set of knob less cylinders with the set on cylinder blocks.
