Our Year 3 and 4 team were very excited on their journey to Belle Vue Primary School to take part in the annual maths championships. We were up against five other primary schools and had 6 rounds of hard questions to get through.
Our first round was called ‘Mystery Number’. The children were given 4 numbers and a target number to make. They had to use all 4 numbers to make that target number.
We had to make 24 with 1, 1, 4 and 8. Mr Wilde did 8-1=7. 7-1=6. 6x4=24. Is there are another way?
Round 2 was called ‘Suguru’. It looked like sudoku but was nothing like it at all! A rectangle was split into various cells. If the cell was only 1 square, number one went into it. If the cell was 2 squares, numbers 1 and 2 went into it. There were some numbers already in place but you couldn’t have the same numbers next to each other.

Our next round was called ‘WODB’ (Which One Doesn’t Belong). The children were given 4 different mathematical images or numbers and had to choose why each one could be the odd one out mathematically (and give a reason for it). We could all find at least one that could be the odd one out but finding all 4 was tough! Have a go at this one. The bottom left rectangle is the odd one out because it is the only one with 6 squares inside it. Why might the other shapes be odd ones out?
Round 4 was ‘Quadrilateral Construction’. The children were given dotted paper full of 3x3 dots. Using the dots, they had to try and make as many quadrilaterals as they could. We know about squares and rectangles but the children had to make 16 different sized quadrilaterals. Mr Wilde and Mr Hughes managed to make all 16 with just one minute to spare on the timer!
‘What’s the Word?’ was our penultimate round. This was lots of maths words jumbled up. All we had to do was un-jumble the anagram and get the maths word. e.g. LEHOW is the word WHOLE. This was harder than we thought! What do you think these could be (there are some clues to help you):
- LALSHOW (You might see this at a swimming pool).
- SOTDEL (Think about brothers and sisters).
- HEPERS (The world is one of these).
- SEEDIB (Next to).
- RENTAPT (These can be repeated).
- SEVENIR (You can check with this).
- RICENDLY (A can of pop is one of these).
- LEANECS (A type of triangle).
- TEAROT (Turn anything).
- CORDPUT (Sometimes the answer).
Countdown was our last round. The children were given a target number and 6 numbers to make that number. We got 5 points for getting the number exactly or 2 points if you were within 5 of the target number. If you want to make 255 using 3 4 5 9 25 50 you could do 50 x 5 + (9-4).
- How about making 441 with 5 4 10 1 25 100?
Or harder ones:
- 137 with 4 7 5 6 50 and 75.
- 298 with 6 2 75 50 25 and 100.
Have a go yourself here.
Our representatives worked really well together but didn’t make it through to the next round unfortunately. Well done to all those who took part.
