Observing maths in Room 9

I watched Karen S. teaching a maths lesson in her Year 3 class.  I found it valuable to see practical aspects of how she set up the lesson.

Karen had the problem set up in modelling books for the groups to use.  The problem was: "Mrs Schwenke bought 3 groups 15 currant buns from the market.  How many currant buns did Mrs Schwenke buy altogether?

Karen put the children into 3 groups of 4 and got them to explain what was happening in the story.  She used the 'talk moves' language, saying "Can I revoice it for you?"

When the children understood what the problem was about they worked with their groups - Karen chose who was going to be the writer for each group (everyone wanted to write).

When it came to presenting the answers Karen put the children into lines.  When a group was presenting and drawing circles on the modelling book she asked "What do the circles represent?"  I thought this was a good idea, making the connection that the circles represent something from the problem.  Karen was encouraging, saying "Well done for being brave and attempting this," reinforcing positive attitudes towards maths.

After the children had presented their answers Karen made the connection that the problem could be represented as 3 x 15, which was the same as 15+15+15.

Lilianne reminded the children about splitting numbers, that it could be worked out as 3x10 + 3x5, so 30 + 15 = 45.  She reminded them that this is called the distributive law.

Takeaway:  I liked the way that Karen glued the maths problems into modelling books to keep track of them and so that the children could read the problem close up (one of the maths mentors mentioned that this affects their processing of what they read).  I liked the way she set up her groups with everyone sitting in lines and a specific job in the group for each person.  It was good to see the way she used the language from the talk moves and that she encouraged the children for being brave and standing in front of the class, acknowledging that it could be difficult to do this.

Observation 29/6/17 - Maths

I watched Siale’s maths today in Room 7.  Half the class were doing repeated addition with her and the other half were working on independent problems.


First, Siale revisited the group norms and reminded the children that the norms apply to any group, like a sports team too.  She used humour - “Remember we are family, don’t let the little red hen do all the work” to reinforce this.


The class were doing a repeated addition problem.  “If Anzac had $2, then his nana gave him $2, then his uncle gave him $2, then his mum gave him $2, how much money did he have altogether?
Siale asked questions to clarify:
“What is the problem about?”
“Who is in the story?”
“What did she (Mum) do?”
“How do you know?”
“How many numbers are there?”
“What’s it called?” “Repeated addition.”


Then she said “Ok.  Let’s attack the problem.”


I liked the way she asked questions that drew out the children’s thinking.  


After the children had worked on the problem for a while, Siale rang a bell to signal it was time to stop.  I liked this non-verbal signal - it reminded me that I could use my bell for this.
I also liked her reminder for putting away the pens - “Lid on, pen down, lid on, pen down.”


Two groups presented their answers.  Siale was careful to position them so that they weren’t blocking the board.  After they had explained their answers she brought the rest of the class to the mat and talked to them about repeated addition and how that can be represented as multiplication, the ‘x’ sign meaning ‘groups of.’  She got the children to role play making 6 groups of 2, and 2 groups of 6, showing the reversibility of these factors.  


She then modelled place value in this kind of problem - “If you know that 2 + 2 = 4, you know that 20 + 20 = 40, 200 + 200 = 400 and 2000 + 2000 = 4000.  

Takeaway: From observing this lesson I saw the power of getting children to role play the problem, giving a visual representation.  It was interesting to observe Siale’s careful questioning and this has given me ideas about the way I will launch maths problems in my class.

Maths in Room 21

Today on my PRT day I observed a maths lesson with Year 5 children, as I have been learning about the 'Bobby Maths' approach.  To start with the teacher, Niu, got the children in pairs to talk about the maths norms - they clarified what some of these meant.  For example, for "Depth is more important than speed" one boy said "Depth means going deep into your brain."

Niu also clarified the expectations for the maths programme - that children need to contribute to their groups - "No passengers" and need to ask questions if they don't understand.

The problem they were working on was one they had done for homework "If 297 people attend a church and 229 stop attending, how many will be left?"  There were a few variations on this problem and the children were able to select which one they wanted to answer.  The teachers in this classroom had identified subtraction as an area that needed work so were focusing on this.

The children got into small groups (4 is the ideal size) and worked on solving the problem.  They had a range of strategies - some split the number into hundreds, tens and ones and subtracted using these, one group used an algorithm, one group used materials, one used a number line...

After about 10 minutes the groups got back together and each one had to demonstrate their strategies.  The other groups were encouraged to ask questions if they needed clarification and the teacher asked them to check that they could add their numbers together to check that their equations were correct.

The main learning I took away from watching this was that children were discouraged from putting their hands up so that everyone was engaged, not just those who wanted to put their hands up.  I need to check whether this was the policy in all curriculum areas in this class or just in the maths programme.  I noticed that this increased engagement and the idea of 'no passengers.' I will be interested to see how this approach works with my Year 2s.
