Rounding to 10, 100 and 1000

I can’t believe I haven’t made these slides before.

I have a group with lower prior attainment this year, so I wanted to really try and be explicit when teaching this.

In my example I went for both a number and a place value grid.

I’ve used the place value grid a lot more this year. It was useful to highlight the tens/hundreds column and talk about rounding to this column. I think I’ll stick with making the grid way more explicit when I teach rounding. It worked well.

There’s quite a bit of mini whiteboard work here, because I’ve found that this stuff is fairly easy, but sometimes students need a few cracks at it to make sure they’ve got it. I project a question for them to do on their mini whiteboards, then I explain it. I generally move on to the task only when the majority are displaying right answers. Then I can focus on the students who need a bit of extra support.

There’s a Blooket link, too. I am still into Blooket. I think it’s quite fun as a little plenary.

If you’ve got a suggestion or some feedback, get in touch on Twitter. Last week’s resource provided some really interesting discussions, especially about questions that require you to ‘add the brackets to make this sum true’.
