# The Tall Tower

##### Stage: 1 Challenge Level:

Students from Lumen Christi Primary School’s Mathematics Extension Program (MEP) worked together on the Tall Tower problem.

Together we found lots of different pathways to travel down the tower collecting spells.
Most Spells – Ben
1 + 3 + 4 + 6 + 5 + 7 + 8 + 10 + 9 = 53
Least Spells – Krishan and Chloe
1 + 3 + 5 + 7 + 9 = 25
Exactly 35 Spells – Joanne
1 + 3 + 4 + 6 + 5 + 7 + 9 = 53

Also Julian at the British School in Manila in the Philippines wrote:

Most: 1-3-4-6-5-7-8-10-9
Least: 1-3-5-7-9
Exactly 35: 1-3-4-6-5-7-9

Finally Lola at Wicklewood Primary School said:

The highest amount was 53 by 1,3,4,6,5,7,8,10,9.
The lowest amount was 25 by 1,3,4,6,5,7,9.
The one that equals 35 is 1,3,4,6,5,7,9.

I beat my mum to answer 35 spells!

Well done to you all!
