When I first started teaching Year 4, place value quickly became the bane of my planning life. I spent hours sketching out base ten diagrams by hand, only for my pupils to look utterly baffled. Then a colleague nudged me towards the place value worksheets on TES, and honestly, I have never looked back. The Times Educational Supplement platform is stuffed with thousands of teacher-made resources, and the sheer variety available for place value alone is staggering. From partitioning activities for KS1 to negative number challenges for Year 6, there really is something for every ability group sitting in your classroom.
What I love most about browsing TES is the ability to filter by year group, resource type and rating. On a Sunday evening, armed with a cup of tea, I can search for place value worksheets and instantly see which ones other teachers have rated five stars. My personal favourites are the differentiated sets, where the same objective appears at three levels of challenge. I print the bronze, silver and gold versions, and my class genuinely relish choosing their own difficulty. It removes that stigma of being given the "easy" sheet, because the children feel in control of their learning. The preview feature is brilliant too, as you can check the layout and font suitability before downloading, which saves printing disasters at eight in the morning.
Whilst most place value worksheets on TES are free, I eventually splurged on a few premium bundles during a sale, and I do not regret it for a second. A well-structured bundle saved me an entire week of planning when we covered comparing and ordering four-digit numbers. That said, my top tip is to read the comments left by other teachers before you commit. They flag typos, curriculum mismatches and, occasionally, genius adaptations that you would never have thought of yourself. I once found a comment suggesting turning a worksheet into a scavenger hunt around the classroom, and my normally disengaged boys were hooked for a full hour. Remember to leave ratings yourself as well; it takes thirty seconds and helps the entire teaching community keep the best resources rising to the top.
Ultimately, TES has become my go-to destination for place value practice. Rather than reinventing the wheel every term, I now curate a bank of tried-and-tested worksheets that spiral back through the curriculum all year long. My pupils' understanding of thousands, hundreds, tens and ones has visibly deepened, and my workload has shrunk. If you have not explored the platform
