Well the end of the earth has not happened. Scientists at Cern have successfully fired two protons round the Large Hadron Collider this morning.
Probably the most famous and expensive experiment ever set up it deserves our encouragement and enthusiasm. Plenty of maths and physics on show!! I’m not going into detail here about the Higgs Boson particle etc, but it is just the kind of news that we need if we are ever going to encourage young people to take up Physics and Maths at A level rather than Media Studies or Tourism!
As Dr Shears explained
“Our experiments are so huge, so complex and so expensive that they don’t come along very often. When they do, we get all the physics out of them that we can.”

Free Y4 maths worksheet: revise addition
Free maths worksheet from mathsblog.co.uk
It has been a while since I posted anything for year 4 so here is a maths worksheet on addition. It is good revision of the terms: ‘What is the sum of…’, ‘What is the total of…’, ‘How many altogether?’ and ‘increase….by…’.
These terms should all be familiar to children in year 4 and they should be able to carry them out in their heads.
When adding three numbers in your head it is a good idea to start by adding all three tens and then adding on the units eg
25 + 36+ 51.
Add the 20, 30 and 50 to make 100.
Then add 5 to make 105, then 6 to make 111 and finally 1 to make 102.
Note this is by all means not the only way to do it!
