# Year 6 SATs - Common Maths Mistakes

With the 2022 Year 6 SATs test coming closer, students are brushing up on their geometry, percentages, statistics and other topics they’ve learned throughout Key Stage 2. In my experience of tutoring, I’ve seen that it’s not always the word problems or multi-step workings that cause marks to be lost; but rather smaller errors that are easy to make when under pressure. Take a look below at some of the common mistakes that students make.

**1. Decimals and place value **

Circle the number that is closest to 20.

19.95 20.1 19.09 20.09 20.201

Mistake: 20.1 (because ‘1’ is the smallest number after the decimal in these options)

Correction: 19.95

**2. Positive and negative numbers**

Put these temperatures in order.

21°C -13°C -24°C 0°C 35°C

Mistake: -13°C -24°C 0°C 21°C 35°C (because 13 is smaller than 24, so it must go first)

Correction: -24°C -13°C 0°C 21°C 35°C

**3. Mathematical symbols**

Fill in the gap with < > or =

11 x 12 ____ 15 x 10

Mistake: > (it’s easy to get these symbols mixed up if you’re rushing through the question)

Correction: <

**4. Indices/Powers/Overs**

6² + 10 =

Mistake: 22 (using 62 = 6 x 2)

Correction: 46

**5. Graphs and Charts**

Altogether, how many children don’t walk to school?

Mistake: 20 (counting the lines on the bar rather than reading the scale on the y axis)

Correction: 200

All of the example questions I used here were from Key Stage 2 SATs past papers. Revise by doing questions, past papers, and maths games to avoid making simple mistakes. For confidence with trickier topics like fractions, angles and transformations, book __here__ for your online session.
