This Year 4 Fraction and Decimal Mistake Investigators resource offers a variety of carefully structured questions designed to strengthen children’s reasoning and problem-solving skills by identifying and explaining mistakes.

Each objective includes four questions: one correct answer and three incorrect options. Children are encouraged to spot the mistakes, decide which answer is correct and explain their thinking.

The questions are intended for group work to spark discussion and collaborative learning. They cover key objectives including: recognise and write decimal equivalents to ¼, ½, ¾; write decimal equivalents of any number of tenths or hundredths; round decimals with one decimal place to the nearest whole number; compare numbers with the same number of decimal places; find the effect of dividing a one- or two-digit number by 10 and 100; and solve simple measure and money problems. A range of visual representations are provided to support children's thinking.

If you’re looking for a resource that helps children develop their reasoning skills while becoming more confident, investigative learners, this is the perfect choice!
