I think, I notice, I wonder...

We have been learning to think like Mathematicians. We have been thinking, noticing and wondering. This stimulates curiosity and helps to make new connections.

Please add to our slow Number Talk below. What do you think, notice, wonder?

 

Our Array City

Array City

Today the Year Four kids made an Array City. Each person made a different building to put on the wall. On the buildings there were time tables to help us remember them.

An array is equal rows and columns. We can make equations from these like 7 X 8 = 56 or 8 X 7 = 56. We can also do repeated addition. Some kids based their building on a real buildings and some just made it up. Now that you know what an array city is you can make one!!

We have been learning about arrays because it helps us to visualise Maths in different ways. It also helps us to develop "Number Sense". We have been thinking about multiplication, division, repeated addition, fractions, area and shape! It is great to see how Maths is connected and how we can think about it in different ways. 

What is Number Sense? 

Arrays

We have been investigating arrays. In our number talks we discussed the definition of an array...

Henry: It is a group of objects in a different arrangement.
Oscar: For example, it could be 4 X 4 or 8 X 8
Edie: It is objects that you can multiply to see how many there are.
Henry: You can also add
Janne: Or count them all.
Hugo W: It needs to be the same amount of objects up and down.
Parker: Yes, columns and rows.

We have been adding some of our arrays to the Padlet below. Challenge: Let's see if we can add as many arrays as possible this week.

Our friends at Auroa School have also made their own arrays. Check them out: https://mrwebbauroa.blogspot.co.nz/2017/08/r3-mathematical-arrays.html

Number talks is a great way for students to learn from one another. It is also important to see how they solve problems in different ways. 

In Jo Boaler's Ted Talk, "Believe in your Maths Potential" she says that it is important to see Maths visually. People visualise Maths in different ways.
