Teaching maths session on operations.

 

In one of my class sessions with the Seniors we learnt about different Maths operations. Our learning intention was:
WALT: Make a number in many different ways.
 
 During the whole part of the class session I went through what operations were with the students. We talked about that + (plus)  means when you add two or more objects such as counters or lollies   to get a  end sum. For example: 10+20=30. We talked about how that sum is interpreted as- ten plus twenty equals thirty.

We talked about the - ( Minus sign). How minus is also known as take away. For example if you started of with 27 apples and I ate 7 of them you would have 20 apples left.

We talk about the times/multiplication sign and how  2 times 3 is also known as 2 groups of 3.
For division we talked about how if we have 6 lollies and you shared them equally amongst 3 of your friends each friend would get 2 lollies each.

I modelled a number on the white board for the children and then we talked as a class on how we could use the different operations that we just talked about to create this number in different ways.


This activity gave the children an opportunity to work as a team collaboratively and work co-operatively together and put ideas together on how many different way they could make the target number.
Here are some photos of the children working co-operatively together and trying to find out how  many different way they could make the target number that I gave them.

In relation to co-operative learning I came across this very interesting article By Jan Terwal. In that article that I read it said how "Co-operative learning helps with developing social strategies and social attitudes in students, and to improve
social relations within and between groups."

Cohen(1994) States  "Students
learning is supported when they have opportunities to describe their own ideas, hear others
explain their thoughts, speculate, question, and explore various approaches".  Co-operative learning with each other enable children to also develop skills such as problem solving skills as well as I believe gives the children an opportunity to have their own voice to be able to voice their ideas and thoughts regarding a topic/problem or question.



Here is an example of a few of the groups work and thinking.

















 
 

I was really impressed on how the groups all worked together and how they really thought about how many different ways they could make the target numbers. Some groups not only used one operation but extended their thinking and used two operations in one equation.
