Halving, Doubling - Whole numbers, decimals

[Surferfish]

when she tried the same approach for halving 7.7 she got stuck, so what approach shall i try

Children (and some adults) sometimes have a bit of a mental block when it comes to doing arithmetic with decimals.

The pounds and pence example which you used sounds helpful.

Alternatively would she feel more comfortable halving 77 or 770? Then just divide the answer by 10 or 100.
