5 Topics to Revise for Key Stage 2 SATs

Since the White Rose Maths Hub began creating questions for Diagnostic Questions just a few months ago, there have been 337,221 answers given by primary school students all over the country. Perhaps more importantly, 116,437 of these answers have been incorrect.

So, with SATs on the horizon, we thought it would be a perfect time to reflect on five areas of mathematics that have proved particularly troubling to Key Stage 2 students. For each of these areas we have provided some supporting resources that you could use with your classes to help overcome these difficulties, together with a mini 5 question quiz you could give your students to see if their misconceptions have been resolved.

You can find the complete White Rose Maths Hub collection here, which contains all the daily Key Stage 1 and 2 quizzes at the bottom of the page. Alternatively, you can see all the White Rose Maths Hub questions together on this page, and filter them by topic.

We really hope you find this useful.

Discussion:

The confusion between factors and multiples is a common one. Both answers A and B suggest students are muddling up these two related concepts. This question is made all the more challenging by the fact the correct answer is one of the numbers given in the question. Students’ knowledge of multiples needs to be very secure to get this lovely question right.

This question catches out any student who does not pause to think. Answer A suggests students have seen 20%, seen 60, and just assumed they are being asked to work out 20% of 60. Answers C and D are also interesting, implying students may have spotted the correct method to use, but were then let down by their arithmetic skills.

Discussion:

Here we have another example of students confusing two related concepts, this time area and perimeter. Answer A has lured in any students who failed to make that distinction. Interestingly, students answering B may have a sense that perimeter is to do with adding, but have failed to account for the other two sides. Students answering D may be guessing based on the diagram, or made an arithmetic error during the division.

Discussion:

This is one of my all time favourite questions, because each answer clearly reveals a different misconception, and to get this question correct students must be secure in more than one area of mathematics. Answer C suggests students have ignored the inequality sign and just made the two fractions equivalent. Answer A implies students have spotted that a multiplying factor of 5 has been used on the numerators, whereas students choosing answer B may understand the inequality sign but not know how to order fractions. A great question!

Discussion:

Another fantastic question for highlighting specific misconceptions that students have. Answer C suggests that students understand that angles on a straight line add up to 180, but have not read the question carefully enough. Answer B implies students have correctly worked out the size of each angle, but have chosen the wrong one. Finally, students who chose D may well be simply going off inspection. Once again, to get this question right, you really need to know your stuff!
