Hi All...Just wondering if anyone has experience of this...I'm concerned about ds2 who's 6, yr 2 but youngest in year. He's bright, very articulate with great vocabulary, artistic but really struggling with maths. Some days he seems to understand simple concepts, other days not at all. Is not grasping 2+3 = 3+2, counting in 2"s, but can do 5"s & 10"s and frequently writes numbers back to front, and double digits are mirror images..so back to front and reversed!!!! Any thoughts? TIA....
