Over the last two weeks we have been exploring measurement for maths, focusing on length. We used two different contexts to practice our measuring skills. We made paper planes and measured how far they flew. We made one modification to our planes and tested them to see if it helped our planes fly further. We measured and compared wingspan and flight distances.
This week on Monday Mrs Jackson bought out a photocopy of an enormous hand print! Our challenge was to see if we could create a formula that we could use to determine how tall the giant was using the measurements from the hand print. To do this we measured our own hand spans, length and width and our height. We learnt how to convert metres to centimetres so that we could convert our height measurements. Then we used calculators to divide our height by our hand span. We tabled our data and we found that most of us had similar answers. Most of the answers were around 8 - 9 cm. We concluded that if we multiplied the giants hand span by 8.5 we would be able to tell how tall he would be. He ended up being 2.47 m tall! That is taller than Steven Adams the NBA player! We were glad he wasn't a real giant!
