Today in Maths we had to solve a problem…what happens when all the rulers are taken away and the ones you have been given are ‘horredous’ (as described by Billy :))
Year four had to work in pairs and groups to figure out how to measure different lines without a ruler or when the rulers they have been given are completely bonkers! Everyone came up with their own ways of figuring out how to measure such as using their finger nails or pen lids. Eventually we came up with a set of ‘ruler rules’ in order to make a ‘good’ ruler. We then made our own rulers and use these rulers to test the theory that all the lines were in fact the same length all along…and they were!
Can you remember the rules we created? Post your answers in the comments!
You are not aloud to use a ruler but you can use any other thing in the class. You have to work out the perimeter and the area of the shape. At the end we used rulers to check if we got it right or how close we got.
the trip to the zoo was so fun
