The application contains eleven sets of teaching aids designed to support the teaching of mathematics in its most important stages - from kindergarten to primary school graduation.

LIST OF SETS WITH A DESCRIPTION OF POSSIBLE TEACHING OBJECTIVES:

1. Fishes
- learning to count

2. Donuts
- learning to count
- sets operations

3. Mosaic
- learning to count
- sets operations
- recognition of basic flat geometric figures
- developing the imagination by arranging colourful mosaics

4. Solids
- learning to count
- sets operations
- recognition of basic geometric solids

5. Natural Numbers
- learning to count
- adding natural numbers
- subtraction of natural numbers

6. Integers
- the concept of a negative number
- adding of integers
- subtraction of integers

7. Fractions
- the concept of a fraction
- adding fractions
- subtraction of fractions

8. Decimals
- the concept of a decimals
- adding decimals
- subtraction of decimals

9. Percentages
- the concept of percentage
- adding percentages
- percentage subtraction

10. All Together - Fractions, Decimals, Percentages
- the concept of a fractions, decimals, percentages
- mutual conversion
- adding
- subtraction

11. Circle Slices - Fractions
- the concept of a fraction
- adding fractions
- subtraction of fractions

12. Multiples blocks
- the concept of multiple

13. The Multiplication Table Blocks
- learning multiplication and division
- four types of multiplication tables

14. Number axes
- axis of integers
- axis of decimals
- learning arithmetic with integers and decimals

A UNIFORM WAY TO USE EVERY SET:

Each set is arranged on the screen on a "checkered sheet".
You can move in any direction with the Left Joystick. You can also zoom in or out with the Right Joystick.

Each element from the set can be "dragged" onto the screen any number of times - you are limited only by the size of the "checkered sheet " and your imagination.

Each element can be:
- rotated,
- dragged to another place,
- checked or unchecked,
- deleted.

The colours can be changed many times in the "Mosaics" collection.

The rods from the "All Together" set can be changed in the number presentation mode - fractions/decimals/percentages.

The rods from the "Decimals" set can be put on top of each other to obtain the effect of "eating a positive number by a negative number". The rods representing negative numbers are slightly transparent - so that you can see through them how much of the positive number has been "eaten".

If you think that something is missing or should have some additional functionality - let me know by e-mail.

I have intentionally not implemented the automatic calculation mechanism - showing the Student the current result of his operation - in my opinion it would be a didactic error. This is because he or she can learn this result on his own, cleverly using the remaining blocks - the teacher/parent only has to show him how to do it. The student will learn only when he comes to the result on his own.

I admit that I was very tempted to include the mechanism of changing the numerator and denominator "on demand" in sets containing fractions, so that the Student could reduce the fractions to a common denominator. However, I came to the conclusion that it would be unnecessary at this stage of learning. This functionality is included in my game "Gold Bar Thieves", which under the guise of a game tries to smuggle in the teaching of adding and subtracting fractions.

I wish you effective/enjoyable learning/fun.
