Excel Place Value mixed ability reusable spreadsheets

Reusable mixed ability spreadsheets for Excel / Open Office covering place value tables with exercises involving partition, ordering and most significant place holders; place value from thousandths to a million, depending on chosen ability; fractions with denominators of 10, 100 and 1000 to show decimal place value relationships; filling in missing decimals using tenths and hundredths with reusable number squares; place value exercises multiplying and dividing to decimals by 10, 100 and 1000. I.W.B. versions with working models to show place value columns with partition links. All sheets can be reused time and again with the press of the F9 key to generate new numbers with answers (can be displayed on I.W.B. for self-marking and repeated demonstration) and print to A4 to allow as much practice as required with additional sheets for lessons or extra homework practice.
