 Catalan term or phrase: producte cartesià This is from a list of skills and tasks that a small child should be able to achieve: Sap resoldre el producte cartesià. All I can find is Cartesian product, which apart from the fact I have never heard, I would struggle to do as an adult: a mathematical operation which returns a set (or product set or simply product) from multiple sets - http://en.wikipedia.org/wiki/Cartesian_product I find it hard to believe a tiny tot would be expected to understand it! I'm obviously missing something. Can anyone help please? Many thanks

 English translation:Cartesian coordinate plane Explanation:Spanish and Catalan people often use technical words in school. I think the 'producte cartesià' is what my teachers called 'coordinates'. "Apparently they are called Cartesian because the idea was developed by the mathematician and philosopher Rene Descartes who was also known as Cartesius." To explain Descartes' method, first think about using a street map. If you're trying to find a street that you've never been on before, you look for the street's name in the map's index. Suppose the index says that your target street is located at D12. This means that you go across the top of the map and find "D", and then you go down the side and find "12". You then trace down and across to find the box labelled as "D12", and look inside that box for the street you need. Somebody figured out that this was a handy way to specify the right general area on the map, telling you how far over (the D) and how far up or down (the 12) you needed to go. Descartes did something similar for mathematics. http://www.purplemath.com/modules/plane.htm http://jmathpage.com/JIMSGeometrycoordinates.html I think in this case it's saying that the student can plot points on a plane. For example, it's possible to use pictures or syllables instead of numbers. --------------------------------------------------Note added at 1 hr (2014-09-23 22:03:25 GMT)--------------------------------------------------http://www.visualmathlearning.com/Exercises/Addition_Table_s...

Reference: Producte cartesià

Reference information:
Una manera de treballar la fluïdesa lectora i, en concret, la lectura de síl·labes, és a través dels productes cartesians. El material que he elaborat per aquesta finalitat és molt senzill: es basa en un tauler i uns cartronets amb les síl·labes confegides. L’alumne ha de llegir la síl·laba del cartronet i col·locar-la al lloc corresponent.

L’exemple que us proposo a continuació està format per tres productes cartesians el primer dels quals està destinat a treballar les dificultats entre fonemes molt semblants a nivell gràfic: p/b/d. En aquest cas he preferit no afegir-hi la grafia /q/ per no generar confusions en la pronúncia conjunta amb les vocals.

També podeu crear taules que incorporin grups consonàntics br, bl, pr, pl… Us animeu a crear-ne d’altres?
