14Ancient Chineese vase
15Seeing the architecture with new eyes
16Visual modeling in an IT textbook for 6 grade
- Create compositions by means of the Cubix Editor
in the style of Vasarelly
- Make the construction with the minimal number of
cubes?
17The applications support additional set of
activities
- Tessellating the plane
- Exploring the relation between numbers and their
geometric representation - Developing the notion of a good
definition-description - Finding the right level of formalization when
describing a structure - Art (under constrains)
18Exploring relationships between numbers and
geometrical figures
- Find the volume of the cubes below. Predict the
number in 20th place of the sequence. -
19DALEST in Teacher education
- Teacher training courses for ICT teachers in the
junior high school - at the University of Sofia
- at the South-Western University of Blagoevgrad
- A short course for in-service teachers in
mathematics and informatics from the country in
the frames of Computer environments for the
mathematics education

35Elaborating the descriptions
36What do the students think? the first
impressions
37I liked all the programs since they are fun and
require a lot of logical thinking. I like
mathematics especially when it is fun and
engaging.
The Origami Nets program is superb it has
absolutely no shortcomings and those who havent
tried it will be sorry Origami Nets are also
enjoyable and I can have fun and learn new things
at the same time.
Thanks to these (DALEST) classes the figures are
already turning in my mind
38If only we could have every class as this one!..
What I liked the most was to figure out myself
what to do..
? How exactly?
39What did researchers find
- The option of folding a rectangle immediately
after being constructed contributes to
experimenting with different styles of
constructing the net - It turned out to be suitable to provide them with
figures which could be turned into nets after
concrete operations (such as adding, removing or
shifting some of their parts) and encourage them
to create their own problems - The kids combine debugging with degoaling when
the object they are constructing is not what they
have aimed at they are able to see another
possibility. - It is very useful to shuttle between using and
developing the software.
