Fractions (set of three levels)

A game for training mental counting skills and mastering the concepts of “part” and “whole”. 
The set contains 12 circles, divided into parts. One circle is whole, the rest are divided into parts: two, three, four, five, six, and so on up to twelve. 

“Using the whole circle and its parts in the game,” Nikitin believed , - kids also acquire many ideas about fractions, about their relationships, although for some reason the school postpones their mastery by 5-6 years - to the 3rd-4th grade." In the game "Nikitin's Fractions" there is no clear alternation of tasks, as in other games. Each time, all the parts must be poured onto the table or the floor, and then again placed in circles in the frames. In this case, Nikitin defines the first task: 
a) pour the fractions onto the table or the floor 
b) turn them over with the colored side up 
c) arrange the fractions in piles so as to collect equally colored fractions together 
d) make a circle of the same color from each pile 
e) put the circles in frames. < br>
Sample games (according to the recommendations of B.P. Nikitin) 
1. What are the parts of the circles called (“green quarter”, “yellow half”, one second, one third, one fourth); 
2. Laying one part of all colors in a row: a) in order: put the largest part first, then smaller and smaller ones, and so on until the smallest, so that each next one is smaller than the previous ones. b) place the same parts next to each other, but in a stack. Place the largest one at the bottom, and the smallest one at the top; 
3. Which part is larger: one fifth or one fourth? We superimpose the smaller part onto the larger one and draw conclusions; 
4. How many parts fit? How many quarters fit on one half? How many times is one second greater than one fourth? What parts and how many will fit exactly on one third, but on half? How many times is one sixth less than one third? Is it possible to make a whole circle out of pieces of different colors? What parts do you need to take for this?
