Over a quarter of children within the ages of 10 and 12 cannot add two small sums of money without using a calculator, reveals a new study.
The new research indicated that youngsters are leaving primary school unable to spell, add or do times tables and their parents do not have the time to help them.
Around a third cannot do division or basic algebra while half do not know what a noun is or cannot identify an adverb. Almost a third cannot use apostrophes correctly, the Daily Star reported.
The survey also revealed that over a quarter (27 percent) of children surveyed could not add 2.36 pounds and 1.49 pounds to get 3.85 pounds; more than one in five (22 percent) could not use the correct version of "they're", "there" or "their" in a sentence and almost a third (31 percent) could not select the correct use of an apostrophe from three simple sentences.
Additionally, more than a third (36 percent) were unable to divide 415 by five, while a quarter did not know the answer to seven multiplied by six.
"Maths and English are key skills for children as they enter secondary school, yet our study shows that many are already slipping behind their peers and could be lacking confidence," Nick Smith, head of online tuition at mytutor, said.
