I hope somebody can put my mind at rest. My DD has just turned 6 and is in Yr1. She is making progress in her reading and writing but I'm a bit worried about her maths. She always writes all numbers back to front. For example if she writes 13 she will write the 1 the wrong way round and the 3 will be back to front. Sometimes she notices the numbers are wrong but most of the time she doesn't. Is this normal at this age? TIA.
