Year 3 and 4 Maths Championships
There were 5 teams taking part in this part of the competition. Blanford Mere, Maidensbridge, Straits, St Joseph’s and Roberts. We started off well by being welcomed as past champions! Round 1 was “Make 24”. These started off easy with the numbers 3, 6, 5 and 3. We made this by doing 5 x 6 = 30. […]
There were 5 teams taking part in this part of the competition. Blanford Mere, Maidensbridge, Straits, St Joseph’s and Roberts.
We started off well by being welcomed as past champions!
Round 1 was “Make 24”. These started off easy with the numbers 3, 6, 5 and 3. We made this by doing 5 x 6 = 30. Add the 3 and 3 to get 6. Then 30 - 6 = 24. They got harder though. Could you make 24 with a 1, 2, 2 and 8?
Round 2 was “Odd One Out”. Children were given a range of mathematical sequences and asked to find the odd one out giving a reason. For instance, out of the sequence:
12 3 6 24 8 10
10 is the odd one out because all of the others are factors of 24.
Why do you think 15 is the odd one out of this sequence?:
15 5 50 20 10
Round 3 was”The Language Round”. A word was given and then 4 other words (with letters missing) were given. The children had to work out all the missing letters.
t _ _ _ _ (tally)
_ _ _ b _ _ (number)
o _ _ _ r r _ _ _ _ (occurrence)
_ f _ _ n (often)
Try it with PRODUCT
_ _ _ _ _ _ _ y
_ _ _ _ s
_ _ _ _ e _
a _ _ _ _ _
Round 4 was the “Number Challenge”. We started with a number and then had a range of different operations - x6, -50%, etc. - and had to get the correct final answer.
Try it with 7 as your starting number.
x6 -14 divide by 7 +14 divide by 10 x7.
Did you get 35 as your answer?
Round 5 was “Codes”. These were phrases that were a mixture of numbers and letters.
52 W in a Y = 52 weeks in a year.
How about these ones?:
8 t on an o. (Clue - slippery customer).
3 w on a t. (Clue - Reception children love these.)
360d in a c. (Clue - All the way around).
5 t on a f. (Clue - 10 on a pair).
26 l of the a. (Clue - Made up of 5 v and 21 c).
9 l of a cat. (Clue - Paws for thought on this one).
100 y in a m. (Clue - We are in our third).
24 h in a d. (Clue - Tick tock).
29 d in f in a l y. (Clue - One in every 4).
90 d in a r a. (Clue - 4 in a c).
4 s in a y. (Clue - S S A W).
100 p in a p. (Clue - Ker-ching!)
At this point, two teams were in joint first and the team in 2nd place were only one point behind - only 2 teams were going to go through to the final.
The final round was our favourite, “Countdown”. A target number was given along with up to 6 numbers that you could use to make that number. We got the first number spot on really quickly but went straight up to the last 10 seconds allowed getting the answer for the second set of numbers. Roberts went through the next 2 sets of countdown questions easily, getting the number quickly and exactly right.
And that was it. Roberts did it again - 1st place (with a 5 point lead!)
We had a great time and thoroughly enjoyed the questions (although we found the word rounds, language and codes, the hardest). Well done boys.
