Give a number between two numbers with one decimal place, e.g. 2.5 and 2.6 Fun activites, warm-ups or games needed to teach decimals to a group of low to average ability year 6 children. Where to start, ways to progress and secure understanding needed please. I feel like I'm missing something. I've also found decimals the hardest area to teach (I don't know why) Can you help? I hope so.
