I would say:

- Connect to play, inquiry, choice
- Have materials available that give lots of options and connect with mathematical structure
- Activities that encourage thinking and talk
- Students writing to express their mathematical ideas

I'm impressed by how Madeleine Goutard got her students writing maths. It was important to her that her students had agency, had their own thoughts and mathematical experiences, which they wanted to express.

On Twitter I saw classes celebrating their hundredth day. I'd never done that, but it comes about the right time of the year for my 5 and 6 year olds; just as lots of them are really ready to think about numbers around 100. We celebrated last year, and it was good.

I'd also heard of people doing a kind of number of the day thing, where every day the students got to say something about that number. I had mixed feelings about it. I didn't want the students who were still not sure of their teens numbers to feel out of their depth or not contribute when we got to the bigger numbers. But, on balance, I thought it would give the students lots of experience with gradually increasing numbers, giving them a predictable format, and a supportive context for writing their own equations, scribed by me. I would try not to 'steer' them too much, just watching what developed. We'd give about ten minutes to it each day, more if we did some practical work linked to it.

So we began with 1. I wrote what they said on the whiteboard and usually tweeted it and kept it.

Day #1: What do you know about 1?— Simon Gregg (@Simon_Gregg) September 4, 2017

'1 is the smallest number.'

'No, zero is smaller.'

'But 1 is the first number for counting.' pic.twitter.com/hvw5a5yXWg

I added the subsequent days to that thread. It's hard to follow on Twitter because it's branched. The days are also here in this album. A vital tool in all this was our magnetic hundred square, which we gradually filled with the numbers, swapping the blue-red sides as we discussed different aspects.

At the beginning there were a lot of 'it looks like'-type observations. After a few weeks of them, it was getting a bit repetitive, and I wanted to see more of those equations and I gently discouraged them. We also had a lot of inequalities, bigger than, smaller than. I wrote this out at in words at first, and then thought, actually, > and < is easier for the students to read than the words. It's funny, inequalities hardly came up at all with my class last year. This year they like them. I didn't manage to scribe everything. For instance, for 9, SB said he knew 4+5=9 because 8 is 4+4. (Why didn't I make more of that?!)

At 19, a little number-writing practice. I didn't call it that. We looked at different ways we could number these hexagons.

You can see a thing starting to develop here. Perhaps it was the materials and the counting in tens, but the students began to express the numbers as a number of tens plus a single-digit number. I wasn't asking for this particularly, but, despite the reduction in variety, I was pleased because that way of seeing numbers reflects our place value system and helps to make sense of what we say and write.

For twenty-five we gave them homework over the weekend (we don't give this often): to number the square tiles any way they liked.

It seemed to help to tune in to equations. (Now, looking at AF's response, I wonder why I didn't make more of that!)

For twenty-nine and thirty, I threw in a tray of eggs. The students were starting to see numbers in different kinds of groups now.

This was hotting up! I quickly printed out an empty tray of eggs and got everyone to write their way of grouping the eggs as an equation.

We sometimes counted our numbers. (I'd do that thing we do where they had to follow my finger which would trick them sometimes by going backwards.)

At thirty-six, a good opportunity to count in twos came up:

HA enjoyed the tautology 45=45. MM was enjoying big numbers, something that was to continue, and spread. Infinity!

We often got the little whiteboards out first, so that everyone was writing now.

(Look at that 47 <>47 at the top. Inventive.)

By fifty-six, the equations were starting to get a little unwieldy.

I wanted to make sure this tens and ones thing was making sense to everyone. We used the rekenrek to represent numbers a few times:

And also the Dienes tens and ones inside a 100 square:

At sixty-three we shook it up a bit, using Cuisenaire rods:

And what about green?

We arranged a hundred things. For homework over the holidays, we asked students to arrange a hundred things at home. We were getting books ready for the big day too, and beginning to read them.

It's been a joyful ride. And I've been able to see my students develop in their thinking and inventiveness. Of course we went a little beyond 100. But that's another story. There's lots I've left out and it's already a long post. (See the album if you want to see all the days.)

You must have a certain endurance if you've made it this far in the blog post. As always, I'm interested in your thoughts. Just writing this, I've seen things I might have done differently. Maybe there's something you don't agree with - I'd be interested in that too!

I made an effort to write equations with the sum at the beginning sometimes. Students often get the idea that = means "and here comes the answer", like when you press equals on a calculator. Sometimes I'd say "is the same as" instead of "equals" too.

I added in manipulatives at various points, to keep it different, to make connections with other knowledge, and to provoke different ways of looking at the number. At eighteen, we arranged eighteen pegs on pegboards

and I asked how they had arranged them:At 19, a little number-writing practice. I didn't call it that. We looked at different ways we could number these hexagons.

Some people did it in various spirals, some in lines.

For ten and twenty, we got the ten frames out first:

For twenty-four, we first counted out twenty-four pattern blocks.You can see a thing starting to develop here.

For twenty-nine and thirty, I threw in a tray of eggs. The students were starting to see numbers in different kinds of groups now.

I think I added in that 30-1=29. We hadn't seen any subtraction yet, and I wanted to open up that possibility.

On day 30 there was a flood of ways of seeing:

(Here X arrives. SB said it and explained it both ways, so I introduced the sign. Early I know, but it turned out to be useful. I was conscious, as we progressed, that there would be children who wouldn't grasp this, so I often paraphrased it as "lots of" and gave the choice of writing it either as repeated addition or as a multiplication.)

This was hotting up! I quickly printed out an empty tray of eggs and got everyone to write their way of grouping the eggs as an equation.

We sometimes counted our numbers. (I'd do that thing we do where they had to follow my finger which would trick them sometimes by going backwards.)

At thirty-six, a good opportunity to count in twos came up:

At day 44, AA and EV both said an equation that had a subtraction in it. I highlighted them:

Most days there was something to remark on. Look at this lovely series:HA enjoyed the tautology 45=45. MM was enjoying big numbers, something that was to continue, and spread. Infinity!

By fifty-six, the equations were starting to get a little unwieldy.

and the next day, I asked if I could just write 5x10 to say 5 lots of ten.

I wanted to make sure this tens and ones thing was making sense to everyone. We used the rekenrek to represent numbers a few times:

And also the Dienes tens and ones inside a 100 square:

At sixty-three we shook it up a bit, using Cuisenaire rods:

We looked at how the ones, threes and sevens fitted exactly:

The next day, sixty-four, I asked if the blacks would fit exactly again:And what about green?

Seventy-five came, and MC was on fire, first of all talking about patterns in the hundred square:

then counting the empty green squares at the top:
Students were very particular about it being an equation, not just an expression. But they were cool about whether the = came near the end or near the beginning.

We had to take numbers off our hundred square to keep track of TT's meandering. Putting them back on is always interesting:

The excitement at approaching one hundred was building.

We weren't going to fit this all in in one day - there would have to be at least a week of celebrations and investigatins!

*One is a Snail, Ten is a Crab*is a great book - all about seeing numbers in different ways. We made some more ourselves, finding ways to make ten with just the animals in the book:

We counted to twenty using Cuisenaire rods to represent the animals:

and then made one hundred, using Cuisenaire rods:

writing how we'd done it afterwards.

We did similar things with the wonderful

*All the Little Ones and a Half*.'It's day one hundred!" |

Love your recommendations for encouraging mathematical thinking at the beginning! I’ve noticed a lot of students improving their thinking a lot because they are writing (their own annotation —not copying mine or doing a worksheet). I also love how you describe how their thinking develops and how you guide it (gently discouraging “it looks like” observations. Great post!

ReplyDeleteThanks, Lee!

ReplyDeleteI've just read a piece by the author Adam Grant on agency:

https://www.nytimes.com/2016/01/31/opinion/sunday/how-to-raise-a-creative-child-step-one-back-off.html

Thank you for this. I teach Kindergarten and it's a good reminder for me to start doing more number talks and math in general with our youngest learners.

ReplyDeleteHi Jenny - if I was to pull out one thing that would travel & hit the spot for the children, it would be the egg box with 30 eggs - which you could do on a smaller scale. Also the books. One is a Crab is great!

DeleteThis makes me incredibly excited to start teaching Year 2 next year. Thanks Simon¨ Also, wondering where you bought those fabulous wooden (?) frames for the hundreds chart so the kids can put the cuisenaire rods in?
