Talking about digits moving one column to the left when you multiply by 10 is certainly conceptually better than talking about moving the decimal point, but some pupils seem to find this difficult to grasp. To help out I’ve made this kinaesthetic resource for multiplying and dividing by 10, 100 and 1000.
The idea is you laminate all the sheets first then cut out all the numbers on the second sheet. Pupils can place numbers on the template sheet which then tells them which direction to shift the digits and how far depending on what operation they would like to do. Attached is also a worksheet of questions (answers included) that pupils can solve using the number cards and template.
To introduce the main ideas you could use this interactive applet which shows the digits moving columns.
