Read full description

Eureka 2 is an application designed for the student to start in numbering as well as acquire the first experiences in arithmetic operations. Like Eureka 1, it is a tool in which the adult can configure the activities according to the level of learning as well as the interests of the student. The activities are 100% customizable, this implies that Eureka 2 allows you to grade the difficulty, you can edit the images that are used, it offers the possibility of reinforcing the orders with an added phrase and it makes it possible to include videos as an explanation of the activity for the cases that require it. As in the previous edition of Eureka, there are two profiles; the one that corresponds to the teacher/adult who edits the activities and other profile for the student who performs them. The App has 4 types of activities: - Amounts. The student can compare quantities intuitively by visual relationship. The elements appear distributed in two formats: balance and tower. - Numeric system. The interaction of the student with the game allows us to work the rules of our Numbering System: decimal and positional. The game options are three: representation of any number of up to 4 figures, addition and subtraction. - Composition. With this activity you can count objects, as well as compose a total of elements from the sum of two groups. It is allowed to work the subtraction, also of visual way, facilitating in all the cases the obtaining of the result. - Numeric line. In this activity several objectives are approached: make additions, subtractions, count up two by two, five by five ... or place numbers in an ordered numerical sequence. You can create unlimited activities of each type and can be grouped into collections defined by the editor based on the theme of the activity, level, course, etc. The activities can also be shared by email, messages, etc.
