### Estimation of Candles arranged in a pattern

Can you estimate the number of candles which are
arranged in a particular pattern.

In the attached video, I have explained the calculation of actual count using matrix.

1. Ooh, I like that lots! They're in a pyramid! I think I can work this one out...

2. Thank you Mr Gregg. I also added the worksheet as a link to show the total.

1. Brilliant! That shows the working out so clearly! I wonder if other people will estimate the number of candles, or whether they'll work it out carefully like you?

4. I think that 10 is too small and 50 is too big my estimate is 35.

5. I think 100 is too big and 15 is too small, my estimate is 35

6. An excellent question. Super explanation of how it was set out and the total calculated. This will be really useful when we look at square numbers too. Well done.

7. Shriya,I think the smallest is 39 and the biggest is 73 but my estimate is 56.
