Hi. I'm a trainee and I'm on placement at the moment. I'm with a year 5 class and at the start of each of their Numeracy lessons the teacher gives them a maths sum test to work from and they need to write the answers in their Numeracy book. Today in Literacy, a child from the lower ability group asked me how to work out 5-0.01 or something to that affect and I found it very hard to explain how to work it out, since the child didn't have a good understanding of place value. The positioning of the numbers didn't seem to mean much to them. Can someone tell me how they would explain how to work this out, to kids please? They are encouraged to work things out mentally if they can but they can write things down if they need to. Thanks in advance.
