【产品描述】
盛有粗糙面及光滑面的木板十块,分别按粗细程度区分成5级、每级各两块木板.
触觉板3块、木盒一个
为3块有粗糙面(砂纸)的长方形木板.
A板粗糙面(砂纸)及光滑面(木质)各占一半的木板一块.
B板与A板相同的粗糙面光滑面交互组合的木板一块.
C板由五级粗糙面所构成的木板一块.
【教育目的】
直接目的:
培养幼儿粗糙与光滑的触觉感和分析比较的思维能力。
间接目的:
1.培养手部肌肉运动的控制力.
2.手眼动作的协调.
【操作使用】
1、将触觉卡放到桌上.
2、老师从坐在小朋友右侧.
3、老师从木盒中找出较细的砂子木板各一对,共四块放在桌上。
4、老师先拿起一块最粗板放在小朋友面前.示范触摸的办法.此左手按住板子左下角.右手指由外向内轻轻抚摸.
5、让小朋友试着做做看.
6、其次给小朋友另一块比较细的板,等也抚摸过后询问:"和刚才那块一样不一样.
7、再给他一块最粗的木板 轻抚之后问看看:"有没有和这块同样粗细的?"如果小朋友从最先的两块木板中发现相同的,就让他将相同的配在一起.
8、另一对较细的木板也轻抚过后排在第一对的下方,左右并排.
9、以这种办法从2对流块板子渐渐增加木板的数目进行练习,直到10块E板全部能配对为止。等小朋友熟练运用上述操作方法后,进行闭上眼睛的配对练习.
10、将10块木板放回盒子里端回教具柜.
按粗细顺序排列
1、将触觉卡连同木盒搬到桌上.
2、老师坐在小朋友的右侧,
3、老师在五组粗细不同的5组(10块)触觉卡中各级选一块,合计五块,不依顺序放在桌上.
4、然后从这五块粗细不同的板了中抽出一块,让小朋友摸摸看.
5、其次再抽出一块让小朋友辨别粗细.用这样的方法比较,将粗糙的放在左边,把5块板子由左向右依顾序排列.主要方法是将触觉板全部摸过一遍,之后再一边触摸比较,一边排列.
6、将5块板子做完序列之后,再闭上眼睛进行练习.
7、给小朋友反复练习的机会.
8、用完触觉扳后全部放进木盒里,放回教具柜上.
辨别粗糙、光滑不同
1、介绍教具给小朋友认识,并准备桌子.
2、为了增加练习者手指的敏感度.可先用温水洗手.用毛巾擦下双手后,以光滑的手指开始练习.
3、取出A板放在桌上.粗糙面的一边靠近小朋友.然后老师坐在小朋友右侧.
4、老师先示范板的触摸法.
首先用左手轻压住A板左下角,使木板固定不动,右手在左边粗糙部分以全部下手指轻抚,反复数次.
5、让小朋友试试看.当小朋友进行练习时,老师一边说。粗糙好粗等词,让小朋友跟着讲.动作和名称练习同时进行是本练习中很重要的一环.
6、然后右边的光滑面也用同样步骤进行,同时进行名称练习.例如:"滑滑的"“很光滑”……等.
7、让小朋友轻轻触摸的机会直到熟悉之后,才进行闭上眼睛的练习.
8、将A扳放回教具柜上.
9、B板、c板、也用同样的要领进行.
C板、的粗细层次感多加体会.
C板、使用的词汇有:“比较粗、更粗 、最细”等.
10、给小朋友反复练习的机会.
11、用完触觉扳后全部放进木盒里,放回教具柜上.
【温馨提示】
关于抚摸触觉的手部动作.在操作使用的手部动作,都是由外侧向内(由上向下)的方向.这是手部运动的控制能力,并成为学习写宁前的间接预备.为了配合本国文字的运笔方向,撮作也可尝试由左向右,改为触觉板的放置方向.
A080Touch Boards With
Box
A box containing two sets of rectangular, wooden tablets with different grades of sandpaper. There are five pairs.
Three rectangular boards:
Rough and Smooth Board 1
One divided into two halves: the first half is polished and the second half is covered in sandpaper.
Rough and Smooth Board 2
One divided into ten strips: five strips are polished and five strips are covered in sandpaper as with the previous one.
Rough and Smooth Board 3
One divided into five strips from very rough to nearly smooth, starting with the same grade of sandpaper that is used in the previous boards (the sandpaper then in gradations of roughness).
Preparation
This is an individual exercise to be carried out on the table without a table mat (Note: Full work cycle to be observed). The child should wash his hands in warm water first.
Presentation
1 The Directress chooses three contrasting sets of touch tablets and sits beside the child.
2 The Directress arrange one set of the tablets and sits beside the child.
3 The Directress arrange one set of the tablets in a column, on the left hand side which we shall call side A.
4 She then arranges the other set in another column on the right hand side, which we shall call, side B.
5 Directress then shows the child how to do the pairing exercise.
6 She uses her left hand to feel the first tablet on side A and keeps the left hand on the touch tablet.
7 She then feels the other touch tablets in turn on Side B with her right hand until she finds the one that matches. The matching touch tablets are placed together, side by side in the middle between the two columns. This process is repeated until all the touch tablets are paired.
8 The Directress may also use the 'Three period Lesson' to teach the child the terminology, 'rough, smooth'.
Presentation
Introduction
Invite the child by telling him you have something to show him. Tell him that before we can work with the material, we must always sensitize our fingertips. (See Sensitizing Fingertips) Bring him over to the correct shelf and show him the Rough and Smooth tablets. Name the tablets for the child and tell him that we will be working with them today. Show the child how to carry the one tablet being used and have him bring it over to the table. Have him place it in the center of the table. Then have the child sit to your left.
Rough and Smooth Board 1
- Secure the board in place using your left hand, but make sure it is not blocking the child’s sight or touching one of the rough or smooth parts.
- Gently place your right hand at the top of the rough half and gently stroke the rough half from top to bottom.
- Remember to keep your hand relaxed.
- Repeat in the same manner for the smooth half.
- Repeat both sides.
- Invite the child to touch in the same manner as you have done.
- Once the child has felt the board, you feel the board in the same manner as before, this time saying “rough” when you are touching the rough part and say “smooth” when you are touching the smooth part.
Rough and Smooth Board 2
- Secure the board in place using your left hand, but make sure it is not blocking the child’s sight or touching one of the rough or smooth parts.
- Gently place your right index and middle fingers at the top of the first strip (the strip furthest to the left).
- Gently trace the strip from top to bottom.
- Repeat for all of the other strips.
- Remember to keep your hand relaxed.
- You can also close your eyes to feel better.
- Invite the child to feel this board.
- Then you feel the board in the same manner as before, this time saying “rough” as you pass over the rough parts and say “smooth” when you are touching the smooth parts.
Rough and Smooth Board 3
- Secure the board in place using your left hand, but make sure it is not blocking the child’s sight or touching one of the rough or smooth parts.
- Gently place your right index and middle fingers at the top of the first strip (the strip furthest to the left and the one closest to smooth).
- Gently trace the strip from top to bottom.
- Repeat for all of the other strips.
- Remember to keep your hand relaxed.
- You can also close your eyes to feel better.
- Invite the child to feel this board.
