Calculation learning software Mental calculation and operations techniques
Presentation This software is intended to elementary school children, who are learning calculation. Thanks to it they will be able to work and play with the mental calculation, especially the multiplication tables.
The level of difficulty can be easily adapted to the level of the child. It also demonstrates the techniques of the four operations and provides a very useful step by step mode.

Topics The following topics are available : •
Configuration This activity allows selecting the kind of operations and the difficulty level that will be used in the mental calculation module. • Mental calculation This activity allows working the mental calculation in an original way based on falling operations that have to be put toward the right solution before they have reached the bottom. -- And with the add-on -•
Operations techniques This activity shows the different steps used to properly solve a complex calculation. A step by step mode helps the child to learn. This module also gives the chance to check a calculation done in a book.

Configuration The configuration is available via the menu item: Game Configure or via the icon It allows configuring the mental calculation module.
Operations selection
Operands selection
Direct and / or reverse problem Maximum score Speed selection Number of proposed solutions
Operation selection The child can select one or more operations. The mental calculation will use only the selected operations. Operands selection For each selected operation the child can tune the maximum value of the each of the two operands. This allows tuning the complexity of the problems that will have to be solved. The bigger the operands, the more complex the operations. If the maximum value for an operand is set to ‘x’ then this operand will randomly take a value up to ‘x’. For instance the following figure shows a tuning to work with additions of numbers between 0 and 10.

Moreover, a checkbox beside the operand maximum value input allows fixing the operand to this value exactly. This allows focusing on a particular table. For instance the next choice leads to work the multiplication table by 7: 7 x 0, 7 x 1, … 7 x 10
Selection of direct and / or reverse problem The software allows posing two kinds of problems: o Direct: the program gives two operands and the child has to find the solution o Reverse: the program gives one operand and the solution, and the child has to find the second operand. This mode allows introducing the symmetric operation. It is possible to use one or both kinds simultaneously. Number of proposed solutions This parameter influences the number of answers that are proposed for each question. The greater this number the more difficult the game. Maximum score and speed selection The maximum score value has an influence on the number of problems that will be submitted to the child. It can be either: o /5, the maximum score is 5 o /10, the maximum score is 10 o /? , unlimited. This last mode is a challenge mode in which problems are submitted as long as the child solves them correctly. The score is thus no more limited. However, the challenge doesn’t take end at the first error (see note below). The falling speed can also be tuned, in order to let more or less time to solve a problem before it reaches the bottom. Note: In challenge mode, the speed automatically increases by one step every 5 problems. Note: In challenge mode, the solutions are displayed one step higher at each erroneous answer. The challenge takes end when the level reaches an upper threshold. The solutions are displayed one step lower at each good answer.

Mental calculation This activity is started via the menu item Game Play or via the icon It is available as long as at least one operation has been selected in the configuration module. According to this selection, the software randomly selects an operation and two operands. It also proposes up to four solutions with at least a right one.
The game purpose is to determine the right solution and to put the problem in the associated column before it has fallen on the bottom. The column selection can be done either via the keyboard or the mouse. ACTION Left movement Right movement Fall anticipation
KEY
MOUSE Click in the column Click in the column Double click in the column
When the fall is terminated a jingle indicates if the selected solution is a good one or not. In addition the good solutions are highlighted by a green frame and the wrong ones by a red frame. In case of good solution, the score is incremented by one. The game is over when the maximum number of problems has been submitted or when the solutions display level reaches the upper threshold in the challenge mode. Anytime it is possible to - return to the configuration module, via the icon - restart the game via the icon

Operations Techniques This module is reached via the menu item Game Learn or via the icon . In this activity the child has to select an operation and two operands. The software will write done the entire resolution as it would be done in a book. A step by step mode helps him understanding the technique of each operation.
Operation selection 1st operand 2nd operand Various presentations for division Step by step indicator Step by step type • Manual • Slow • Fast
In step by step mode, intermediate calculations are shown to help the user understanding. Three kinds of Step by Step are available: • Manual In this type, the user moves to the next step by clicking the mouse or hitting a key. • Automatic slow The steps are played automatically in a slow manner. • Automatic fast The steps are played automatically in a faster manner A selector allow to select one of the various kind of presentation for the division.

When the user selects ‘OK’ button the calculation starts. If the step by step indicator is not activated, the entire solution is displayed:
Otherwise it is played at the rhythm selected by the user.
