The Tower of Hanoi
In Maths we have been learning how to identify sequences and patterns in number. We worked in groups to solve the problem of the Tower of Hanoi. By moving the discs we were able to find a pattern; each extra disc doubled the previous number of moves plus one. Using this information we were able to identify a simple ‘rule’ to accurately predict the next number in a given sequence. Some of us have even begun to find a formula that will predict the number of moves for any given number!
Castle Word Problems
This week we have been working on strategies to solve word problems using the 4 operations. Today we used our problem solving skills to solve different word problems that were displayed in the Nature Garden. We had to look for different types of castles to find the problems for our group; Motte and Bailey, Stone Keep or Concentric Castles.
We have been investigating the durability and permeability of different types of rock as part of our topic on eroding coastlines. First we identified different types of rock as chalk, sandstone, limestone, slate, marble and granite. Then we tested each sample by scratching the surface for durability and by using a pipette to see if the sample absorbed water or not. After testing the samples we discussed our findings in our group to see if they matched our hypothesis.
