<p>I’ve designed 10 fractions calculations (all four operations) including errors based on common misconceptions. These range from basic mistakes to more subtle inefficiencies. Students have to look carefully to identify errors and correct the method. This helps alleviate the stigma of being wrong as they talk openly about what ‘traps’ to avoid. They seem to enjoy the challenge of spotting the teacher’s mistakes! This resource includes Word and PDF files plus handwritten solutions.<br /> “Deliberate mistakes are one of the best way to assess pupils’ understanding and deepen their learning. This is an excellent resource to help achieve that.” Mr Barton Maths</p>

<p>A student of mine wanted to do more fractions of shapes so I designed these, also involving percentages and ratio. There are different levels with a mix of shapes in each sheet. The visual approach seems more appealing to students and it also gets them switching between fractions and ratios.</p>
