Hermit Crab Maths Investigation

Hermit Crab

Maths Investigation

In 4v over the last two days Miss Valvo set us a math investigation task. We had to set up a crab enclosure. We also had to pay for it and to make our money we had to fund raise by doing a sausage sizzle. We had to make a price for each sausage. We had to sell our sausages for more that we bought them for so that we make a profit. The first step was we had to add the price we needed for our crab enclosure. Secondly we had to organise the sausages for their price and we had to buy them. We them said if we sold them all how many dollars left over we had.

Shape Pictures in 4V

Our shape pictures in 4V

by Lachlan, Oscar and Charlotte

In 4V we are learning about 2D and 3D shapes. We had a base shape and then we made it into a creative picture.

Then we had to write the shapes:

  • Names
  • How many Edges
  • How many Faces
  • How many Vertices
  • What they enjoy

The three most popular shapes were square, circle and triangle.

Here are everybody’s pictures.

Using Bead Strings for Maths

In Maths this term we have  been using Bead Strings to practise our counting and number facts. Using the string has helped us to picture a number line in our heads. Miss Valvo introduced us to the BIG Bead String and we looked at all the different ways that we could count the number of beads on the string.

Miss Valvo asked questions to help us with our thinking and counting skills such as:

‘Is there a faster or another way to count the beads?’

‘Which was the fastest way to count the amount of beads?’

‘How many is one more ore one less bead?’


We have also used the beads to play a game called ‘Tug of War’. This game helps us to practise our addition and subtraction skills as well as our counting.


 Can you think of any other activities that we could use the Bead String for?
