The idea of scaling is really important in mathematics, and everywhere in the world, so in Year 4 we've spent seven days exploring it in different ways.
❶ We started off by scaling up shapes drawn on grids. We looked at this:

This is what Rod drew 
Then we made some scaled up shapes ourselves. And we had
lots of them (sometimes it went wrong the first time, an we had to redo it):
❷ The next day we made designs with pattern blocks, with a certain ratio: two triangles to one square. (Thanks to John Golden
for this idea.)
There were streets, cats
Here's a slide show:
What a fantastic journey. Thank you for taking the time to put it all together in one post!

Hi, this is great. I was wondering about the shape activity (squares and triangles) and the paper scaling. What would your key questioning be here? I'm using some of these ideas in my lessons but I'd love to know how you developed and challenged their understanding.
ReplyDeleteThanks!
Thank you so much. I've really struggled knowing how to progress through integer scaling using a practical base to build onto and this has been a great help.
