Sensorial - Knobless Cylinders
Materials:
Red box of Knobless cylinders (vary in height & diameter)
May be done on floor rug or a table mat
General Presentation - Horizontal Grading:
1.Invite the child or group of children.
2.Go over to where the Red Box of Knobless Cylinders is kept.
3.The teacher should name the material for the child, “Knobless Cylinders”.
4.The teacher should demonstrate how to carry the box with two hands (thumbs on the top of the unopened lid and fingers underneath the box).
5.Invite the child to carry the box over to a table.
6.Invite the child to get a table mat and place it on the table.
7.Place the box on the table in the upper left-hand corner.
8.Remove the lid and place it to the right of the box, color side up (you may prefer to placeit under the box).
9.Remove each cylinder at random and place it below the box and lid. Place them in mixed order from left to right in a horizontal line.
10. Find the largest cylinder and place it first in a horizontal line below the mixed order line.
11. Find the next largest cylinder and place it to the right of the first cylinder. 12. Continue until the cylinders are graded from largest to smallest.
13. Replace the cylinders in the box beginning with the largest one.
14. Replace the lid on the box.
15. Return the box of cylinders to the shelf carrying them properly.
16. If you were using a rug on the floor, or a table mat, return it to its place.
Blue Box of Knobless Cylinders:
The Blue Box of Knobless Cylinders vary in height and diameter (same as the Red Box). Do everything the same as the Red Box presentation including using the terminology of large and small, tallest to shortest.
Green Box of Knobless Cylinders:
The Green Box of Knobless Cylinders vary in diameter. Do everything the same as the Red Box presentation except the terminology will vary with degrees of diameter…thick and thin, widest to narrowest.
Yellow Box of Knobless Cylinders:
The Yellow Box of Knobless Cylinders vary in height. Do everything the same as the Red Box presentation except the terminology will vary with measurement of height…tall and short, largest to smallest.
Second Presentation – Vertical and Centered:
Begin as in the first presentation until all cylinders have been removed from the box and placed in random order in a left to right horizontal line below the box and lid.
Pick the largest cylinder and place it on top of the lid. Select the next largest cylinder and place it on top of the first cylinder and center it. Continue until all of the cylinders have been placed and centered.
Repeat presentation with the Blue Box, Green Box and Yellow Box.
Variation #1 – Using more than one box at a time:
Red and Green Boxes - Height
Choose the Red Box and the Green Box and follow the general presentation through Step #12. When both boxes of cylinders have been graded, ask the child if they can find any two cylinders that are exactly the same height? Ask child if they can find any two cylinders that are similar in any way.
Red and Green Boxes - Comparing Surface Area
Choose the Red Box and the Green Box and follow the general presentation through Step #12. When both boxes of cylinders have been graded, place the largest cylinder of each box on top of each other. Point out to the child that both cylinders have the same surface area. Ask the child to continue comparing the surface areas of the two sets.
Red and Yellow Boxes - Height
Choose the Red Box and the Yellow Box and follow the general presentation through Step #12. When both boxes of cylinders have been graded, ask the child if they can find any two cylinders that are exactly the same height?
Red and Yellow Boxes - Comparing Surface Area
Choose the Red Box and the Yellow Box and follow the general presentation through Step #12. When both boxes of cylinders have been graded, place the largest cylinder of each box on top of each other. Point out to the child that both cylinders have the same surface area. Ask the child to continue comparing the surface areas of the two sets.
Green and Yellow Boxes - Height
Choose the Green Box and the Yellow Box and follow the general presentation through Step #12. When both boxes of cylinders have been graded, ask the child if they can find any two cylinders that are exactly the same height? Make sure that the cylinders are close to each other so they may be compared. Now, reverse grading order and see that they are the same height.
Green and Yellow Boxes - Comparing Surface Area
Choose the Green Box and the Yellow Box and follow the general presentation through Step #12. When both boxes of cylinders have been graded, place the largest cylinder of each box on top of each other. Point out to the child that both cylinders have the same surface area. Ask the child to continue comparing the surface areas of the two sets.
Blue and Red Boxes - Height
Choose the Blue Box and the Red Box and follow the general presentation through Step #12. When both boxes of cylinders have been graded, ask the child if they can find any two cylinders that are exactly the same height? Make sure that the cylinders are close to each other so they may be compared.

Variation #2 - Memory:
Follow the General Presentation through Step #12. Then, roll out a second rug some distance away from the first one. Carry the largest cylinder over to the second rug and grade the cylinders in exactly the same way as you did on the first rug. This is the first memory exercise called order to order. The second memory exercise should be mixed order to order. The last one should be mixed order until you get to the middle cylinder and then grade toward the largest cylinder.
Variation #3 - Blindfolded:
After one of the Knobless Cylinder Boxes have been carried to the rug and are in mixed order, have the child use a blindfold. The first blindfolded exercise has the child grade horizontally as in the General Presentation. The second blindfolded exercise has the child grade vertically.
Variation #4 – Horizontal & Matching Cards:
After one of the Knobless Cylinder Boxes have been carried to the rug and are in mixed order, show the child where the matching cards are kept. Take the matching cards over to the rug and place the card with the largest circle on it at the bottom left-hand corner of the rug. Place the cards from largest to smallest in a horizontal line left to right. Find the largest cylinder and match it to the card and place it on top of the card. Continue until all of the cylinders are matched to a card.
Variation #5 – Combined Boxes & Matching Cards:
After two of the Knobless Cylinder Boxes have been carried to the rug and are in mixed order, show the child where the matching cards are kept for combined boxes. Take the matching cards over to the rug and place the card with the largest circle on it at the bottom left-hand corner of the rug. Place the cards from largest to smallest in a horizontal line left to right. Each one of the cards has two circles on them. Find the largest cylinder and match it to the card and place it to the right of the card. Find the cylinder that matches the inside circle on the card and place it on top of the first cylinder. Continue until all of the cylinders are matched to a card.
