Dinosaur Top Trumps

A really busy session today in topic-based maths. Children practised their measuring and converting measurements in centimetres to millimetres. The children learnt about dinosaurs that were 10 or 20 the size of them. They used their dimensions such as head circumference, height and others then multiplied them to find the dinosaur's body dimensions. Before doing that children came up with a formula to help them multiply any number by ten or twenty. We published our findings and rules these on the ShowMe iPad app so that we can help the entire world with our ShowMe videos! Do you remember what the formula or rules are? Does it work wit ANY number? Can you show us and prove it? How about those of you that came up with a set of rules for x20, will that work with any number? Add it to the blog and prove it!

Capacity

We have been looking at capacity this week. What is it the measurement of? So what might I use to measure capacity? What is the unit of measurement? Do I measure it in centimetres? I was really impressed with the way the children checked the scale of the measuring tools before filling it with water to make sure that the data they recorded was accurate. Good job troopers! What tools have you got at home that measure capacity?

The Amazing Romans and the centimetre

We were learning about measurements today. We looked at where the words centi and milli come from and what they mean when you combine them, like centimetre for example. We made our own metre measuring tapes. What did we use our metre measuring tapes to measure? What else could we measure using our metre measuring tapes? We decided that metre measuring tapes were not accurate enough so we decided to use centimetres with our metres to fine-tune and make our measurements more precise. Remind me how many centimetres are there in a metre? What would you measure in centimetres? Would you measure the distance between your house and school in centimetres? Why or why not? Those Romans were just SO clever, but the cleverest Italians come from a special place called Cesinali, Avellino!

Mathematics - 3 dimensional shapes

This week in Maths, class 4 have been learning about the main features of common 3 dimensional shapes. What are the 3 dimensions of a three dimensional shape? If a face is a feature of a 3D shape what are the others? What 3D shapes do you remember learning about this week? Which 3D shape could have cast this shadow in the photo above? Do you agree or disagree with your classmates suggestions? Thanks to Mr. Worbey for helping take the photo!
