LeM? .-, learning and work equipment for arithmetic lessons in elementary school "

My teaching, learning and working materials are intended for the hand of the students, The arithmetic means intended for the classes in question are in each a plastic bag, which is ready to hand on a hook next to the place of the The arithmetic items remain in the classroom and are used to avoid .. losses and exclude damage as far as possible, not after The models presented are for the Calculate with breaks made of gray cardboard Plastic is thought.

Model 1 in bag 1 consists of 100 cardboard disks with a diameter of 15 mm and 1 - 2 mm thieves should in any case be sufficiently physical

The bag also contains Io cardboard disks, 14 cm long and 1.5 cm wide with circular disks of 13 mm diameter glued on, one side red on the other, green. They are called Züg @ in the educational language »Zul et ζ t belong to model 1 10 so-called painting disks made of cardboard _s © cm long and 4 cm wide with rounded corners, called fetaarz ¹ TIaIe" »This compilation of means for that l * and 2 «The school year is new · It has at least never been passed me before _e ¥ em also sees the two-colored discs and trains to me.ItoeliL it is possible to distinguish two numbers from each other» Opportunity gives sick ζ _ο Β _β when adding up, where the starting point appears in red, the added quantity appears green, for the clarity and clarity of the process of the greatest value, or when subtracting, where the subtrahend appears in a different color than the minuend, whereby the quantity difference

The Malseheiben or Malseheiben are used for the visualization of the relationship between the figures, there is a control here # J®f the times, all numbers up to 100 can be flexibly and vividly broken down into their factors, and in the same way, measure ^ measure and divide *, for example we 8 times 8 discs and find 8 times with 8 is 64, noting 8 * 8 = 64Bas ropes, a mirde that is feared and difficult to take by all students, is carried out on the descriptive basis of the division of a quantity aaf © In a given number of times "In Exercise 32: 4 is solved in such a way that 32 is divided into 4 times. Since the beginning of the calculations is the analysis of the numbers, their resolution into factors, the exercise 32s4 moor forms a repetition of the already boiled: 32 = 4 times with S.Iun follows the inversion32 distributed over 4 times is 8 C in each time).

About 100 discs and the 10 times are also carried over into the third year of school until the 1 * 1 sits in all its disciplines and can continue to deal with the large 1 * 1 to 20 rand other tasks with increasing difficulty that with the work with the research means the representation of the ZaMen and deer processes by graphic symbols on which the shape of the Eechienmittel is based, constantly goes together _# So wer «· den die Eechenschieiben. dureM curl edge later fixed by point ©,

In bag 2 with model 2 for the third school year, as mentioned by se & Lon, there are the 100 two-colored discs and the 10 discs for the above-mentioned purposes two-colored mobile tens strips 5 »5 cm long and 7.5 mm wide raid in a box 30 ZaM * linge, two-colored, 6 mm in the bark knife and 2 to 3 mm sioehe Because of their small size ,za & U limge are my children of pain, but they have to go to the Bundertena. country tens fit * I have measured their number at 30 ^ although wax 18 is absolutely needed.

Yes, bag 3 with model 3 are the loose sheets and the times "dropped out" 20 strips of ten and 30 cuffs remain in the bag. In addition to the 10 Hundertertafein, 10 more are bought, further 5 two-colored, collapsible 5 amsender strips, 50 cm long and 5 »5 cm wide, with a plastic disc for calculating with areas of 5 cm in diameter · χ χ For numbers that are more than 5 < Require thousands, 2 students sitting next to each other have to work in partnership® The introduction of the mobile thousands in the range of teaching aids for arithmetic lessons is also a hovum

"I summarize: My teaching, 1 era" and work equipment for the rake " Primary school teaching is a revelation in many ways.

Tmd surpasses all arithmetic tools known to me. It is simple, a lot « usable on both sides and for all disciplines of arithmetic in the (Primary schools a necessary and usable basis «With his help

Both gifted and also less abused and learning inhibited children penetrate the world of numbers quickly and safely. It is of the greatest importance that all children have my resources at hand and can work freely under the guidance of the teacher. The main advantage of my resources is their mobility lamd variability! the immobility - and the tightness of variation - of most of the common arithmetic tools has been eliminated. Every child is busy and can help * with the usual, large-format Jsa «. There was only one student working outside the class. The rest of me were condemned to watch, a boring and on the long run quite exhausting behavior, which soon slackened attention. According to my suggestions, all children have their stuff in hand, a real tool that is worked with # I don't know anything offered on the teaching material max Calculation means that has all of these advantages
