Egg Carton Measuring
Next we had a go at using egg cartons to form a non-standard unit of measurement. This is always a fun activity with young children as it takes the pressure off being able to read real numbers and introduces the concepts of measurement in a very kinaesthetic and practical way. It can also be extended in any way that you like to become an open-ended challenge for older children too.
We had a lot of fun together finding the items to measure and seeing which was the biggest and smallest and which turned out to be identical lengths. We talked about making sure the Eggy boxes were layed carefully in a straight line next to each object and that they touched end to end. There were a couple of instances where the object was slightly too long or too short and so we had to think of a solution. We talked about creating a half sized unit of measurement “The Half Eggy”, and simply cut one box down to be just 1.5 holes long. This proved particularly useful for measuring the apple, as it turned out to be exactly one half Eggy long! And Cakie wanted to be measured too, as well as Pop, and was found to be 7.5 Eggys long, where Pop had been 7! Who knew they were so close in size? Their Mum certainly hadn’t realised!
Extend this activity:
- ask them to draw or write a list of their own chosen objects to measure
- can they find something that is 30 Eggys long? 50? More?
- find out how tall objects are, instead of how long, by using whole closed egg boxes and stacking with them (see this post where we did something similar)
