Hi all you helpful people out there

Yesterday night (again after a long day at school and swimming) my DD and I had a bit of a struggle with decimals.

She is currently in Year 4 and have just started with Decimals. I am helping her out in understanding the ordering and how multiplying and dividing them with 10, 100 and 1000.

Things became tricky when some of the questions we encountered had a a decimal number conversion from kg to g and then m to km.

Both concepts when discussed separately, she knew i.e the multiplication/division of decimals and conversion, but when both of these came together, she didnt quite get them.

Wonder if other mums are seeing the same of their kids in year4 and how are they helping them ?

Yes. Maths at school seems to be a mess for us right now too. And yes, you never get to find out what they were taught or how they were taught it at school so you're left blind with the homework. Not that we get any year 4 homework as complicated as this! Top group, 4c at end of year 3, but homework is addition and subtraction if there is any, and a note to do some timestables revision from time to time.

You could try asking the teacher if she could let parents know with each homework what they have been taught that week and how. You might be pleasantly surprised. But you might not be. Don't know. Our school is like GCHQ.

Show her how the digits move when you multiply and divide and then yes, the decimal point moves the opposite way indeed!

Then she needs to maybe do some more practical things to see that a measurement in centimetres results in an answer which is 100x the same measurement in metres ... so then she'll be able to think at the beginning of each problem "now do I divide or multiply" and explain why ... important to pause and do this thinking before launching into the arithmetic.
