"Project ""Supporting skills acquisition and competences for students with intellectual disabilities"" was implemented by two special schools: Special School Complex in Słupia near Kępno (Poland) and Bishopswood School in Sonning Common (United Kingdom).These facilities are attended by students with intellectual disabilities (mild, moderate or severe) and / or autism who also very often have coupled disabilities (e.g. paralysis of the limbs, hearing loss, amblyopia and many others). Our students face many educational challenges. The most common recurring difficulties are:- impaired ability to perform mathematical operations, e.g. subtraction instead of addition and division instead of multiplication;- inability to match relevant mathematical operations to real situations;- lack of understanding of the relationships necessary to perform memory calculations;- failure to notice numerical relationships;- lack of ability to apply their knowledge, e.g. learned mathematical operations, in new situations;- problems reading and writing.16 teachers (8 from PL and 8 from UK) took part in the project and developed 22 primary competences (10 from UK, 12 from PL) in the scope described above. These educators also developed their methodological workshop to more effectively help students overcome educational difficulties and acquire the skills and competences they need for current and future functioning. To this end, they exchanged good practices, developed new solutions, created innovative methods and tools, and also participated in training, including in the use of Photon robots in teaching mathematics.Thanks to the project activities, the following products have been created, available on page http://zssslupia.pl/index.php/wspolpraca-szkol-ka2-polska-wielka-brytania/rezultaty-i-dobre-praktyki :1.

The plans of organizations participating in the project include further exploitation of results, including in projects implemented on the eTwinning Platform."
