Planned opportunities for oracy are crafted into our Maths lessons, including chances to explain reasoning, disprove/prove conjectures and convince.
I knew that 2,433 over 1,000 was an improper fraction; therefore, I had to see how many thousandths were in 2,433 and from that I worked out to write my answer as a mixed number. Lots of children missed this opportunity and gave their answer as an improper fraction. The number before the decimal indicated a whole number so gave an answer as a mixed number. - Isaac
