We have been looking at 3D shapes because we need to design the packaging for our clocks. Mrs Collins set us the challenge to find all the different nets to make a cube and then consider which would be best for mass production – get the most boxes out of one sheet of cardboard. We were then given the added challenge of imagining the nets were for dice and planning where the numbers would go (remembering that the opposite sides of a dice always add up to 7!); it was much harder than we first thought!
We are investigating 3D shapes this week in maths. We have been learning about their properties and using mathematical vocabulary. Some of us did an investigation linked to Euler – a Swiss Mathematician – to find a link between the number of faces, edges and vertices a polyhedron has.
At the discovery museum we found out all about George Stephenson and his steam engine ‘Rocket’.
We had our own competition. We were given £500 and as a team we had to decide which resources we would need before then purchasing and building our own engines!
It was really tricky ‘balancing the books’ as the best resources were more expensive so we had to decide which ones were essential and which ones we could afford to cut back on. We even had to hire equipment such as scissors! We had to use fractions, measures and multiplication to calculate how much of each thing we would need too, making sure we didn’t go over budget.
All the rockets did really well and looked great, one of them was so fast it crashed into the far wall and broke the record!
We have had great fun this morning… just playing games!
Mrs Collins gave use coordinate boards with different calculations on to help us practice our multiplying and dividing by 10, 100 and 1000. We had to try to get 4 in a row. It was lots of fun and really helped us consolidate our learning.
What a morning!
We came in to find jigsaw pieces all over the floor; a locked chest and a forest of balloons hanging from the ceiling! We had to use a wide range of maths skills:
- equivalent fractions
- equivalent fractions / decimals / percentages
- simplifying fractions
- converting improper fractions to mixed fractions
- prime numbers
- addition …!
Never mind having to work as a team, organise and record information and problem solve!
We made it just in time (earning extra break time!) We had so much fun, we can’t wait for the next challenge!
We have been investigating forces this week. We decided to test different size parachutes to see which were the best. it took quite a lot of planning and making them was much harder than we first thought. We were surprised by the results because the biggest parachute wasn’t the best. there was an optimum size where the parachute was the right size and weight to support the load.
Our ‘Art through the Ages’ Gallery was a huge success!
Well done Class 5!
