We have been talking quite a bit about metric units for measuring length and how you convert from mm to m, cm to m or mm to cm. We did lots of hands on examples where the kids walked around the house and measured items in cm and then mm but I still wanted to find a way to practice moving between cm, mm and m. Both my kids love using Maths dominoes so I had a quick look to see if I could find something useful on the internet. But after a quick search I could not find what I wanted and I did not feel like spending ages searching so instead I decided I would try to create some of our own dominoes.
Nothing fancy but just a way for the kids to practice and hopefully to cement when they need to divide/ multiple by 10, 100 or 1000.
I kept ours straight forward with just black font for everything. And I tried to mix in a combination of easier examples with some harder ones.
However 2 other home educating moms said it would be useful to have a colour version which the younger kids could use if they wanted. The idea being that the colours would help the kids – so 600 mm and 60 cm would be 1 colour and then 90 mm and 9cm would be in a different colour. So I also converted my exisiting dominoes into a colour version as well.
Here are the dominoe sets that I created for the kids.
Changing between cm and mm
Changing between cm and m
Changing between mm and m
I still want to create a complete set where the I mix converting between km, m, cm, and mm in one set – hopefully I will get that done soon.
