Hi there Don't despair! Last year I had the exact same problem, I was planning for just after Christmas and using the Year 6 objectives etc and suddenly had a crisis moment of realising the kids just couldn't do what I was planning. Luckily I have a fantastic headteacher who trusts me as I proposed something completely random. We scrapped Maths for 4 weeks and went right back to basics. I took the children to the hall for nearly every lesson - we started with hundreds, tens, units and place value....the children all had numbers stuck to their jumpers and they had to rearrange themselves.......then comparing/ordering numbers....then addition, subtraction etc. I even did literally 4 bean bags and 3 bean bags - what does it equal!!! We did multiplication as groups of in hoops in the hall..... Then we moved to decimals - children had strips of 10 equal pieces of chocolate, they designed chocolate bars on the back. We added them, multiplied...you name it. There was hardly ANY work in the kids books, we were due OfSTED but I knew that I could justify why I had done what I had done. My kids didn't perform on half termly tests and I realised it was because they really didn't have a grasp of the basics - check your kids - I don't want to teach you to suck eggs but I was shocked at what they couldn't do - I found that of course they can't solve word problems involving multiplication when they don't actually understand what multiplication is! To top off a very good year we got 100% level 4 and 57% level 5 - results like we have NEVER had before - and I know it's not all about the results but we were on track for about 60% at the start of the year so....keep at it!
