Picaa incorporates 5 types of exercises which are intended to cover some of the main tasks of learning:


There are two sets of elements so that the student must indicate the relationship between them. Several variants are contemplated:

  • One to one: The set origin and destination all have the same number of elements so that each element of the original group element corresponds to a destination.
  • Multiple: Origin and destination sets can have different numbers of elements.
  • Identification: One set, origin or destination, has a single element to which they should associate the elements of another set that fulfills a certain property.

This activity is the basis to make lotus, memory exercises, calculation and discrimination.


It presents an image decomposed into pieces of a puzzle that students should be ordered. Educators can configure the puzzle pattern, management of parts and the image on which to base the puzzle.


This activity is intended to enable students to learn concepts by navigating through a hypermedia system. This type of activity can be used to create simple communicators and agendas, showing an initial set of elements related to any issue so that selecting each of them new elements or reinforcing information (for example, an animated video) are shown. It can also serve for the student builds a story as browsing the hypermedia system, observing and selecting images, hearing sounds, showing animations and moving to other pages.


In this type of activity a set of elements is shown so that the user has to establish the correct sequence (for example, order a sentence). Allows the definition of distracting elements, ie elements that are not part of the sequence.


This activity allows to create sets of memory (memory-match) with cards that are hidden initially and turn around every time the user pressed. The goal is to match the same images. There is also a mode where user must match each image with its associated text.


These types of exercises are focused on developing the following skills and abilities:

  • Perception and visual and auditory discrimination.
  • Vocabulary acquisition and comprehension of meaning.
  • Memory development.
  • Improved phonetics, syntax and pragmatics of language.
  • Working hand-eye coordination.
  •  Examine assumptions, conclusions and interpretations.
  • Learning cause and effect.
