Construction of toy Mema

3 and 4 period

During this lesson the children make their toys, and we shall name them Mema.

It is necessary that every child has:

- 9 matchboxes,
- colored in 9 different colors,
- and sticked together becoming a chest of drawers.

Comment for the teacher

The purpose of Mema is to understand how a computer work. The terms they will encounter are the basic terms of programming, regardless on which computer or which programming language is used.

  • It is desirable for all children to have Memas with same colors of drawers, because if they had different colors some of problems were not possible to solve.
  • This problem appears with real hardware (real computers) and is cold compatibility, and is connected with all problems when some computers are not able to run a program, with is written for a different computer.
  • The main purpose of Mema is the help in understanding how the variables behave in main computer memory during a program is running.
  • During this lesson the teacher should avoid definitions of terms. The terms may be mentioned by the way and repeated when needed.
  • The goal is to adopt the terms through understanding the function of them, not through learning by hearth.
