# Maths – Exploring 2D Shapes

In P4/5/6 this week, we have signed up to the Shetland Sumdog Competition so we made a start at climbing up the leader board on Friday.  We are hoping to build on our success in the National Competition last time so it would be wonderful if the pupils could log in at home too and play along.  It runs until Thursday 17th.  Good luck!

These past few weeks, the class have been learning about 2D Shapes.  We have found out about polygons, regular and irregular 2D Shapes, parallel and perpendicular lines, how to find the number of diagonals a many sided shape has and naming quadrilaterals.

All of this helped lead up to this week’s Maths lesson where pairs of children were given either a description of a 2D shape or a specific shape for them to describe using the correct Mathematical terms.  They had to use different materials to make them as accurately as they could.  I was really impressed with the team work shown and their ability to keep working when shapes did not quite come together and when clues had to be puzzled out.  (Sorry for out of focus photos!)

# LEGO Renewables

Emma Chittick, who is a STEM Engagement Advisor for Skills Development Scotland, came in to help us with another STEM wind turbine challenge., but this time we used LEGO!

She set a competition to see which design could generate the most power.  The tricky part was trying to build a strong structure to set the turbine on.  The class also had to consider how they attached their blades and in which direction they were facing.

Everyone was so engaged and worked well on their own or with a partner to complete the task.

Well done P4/5/6!  You did a great job!

# Wind Turbine Challenge!

As part of our topic work, we have been learning about Renewable and Non Renewable energy sources.  We discussed the advantages and disadvantages of these and which ones would work best in Shetland.

Last week, we worked in teams to design and create a wind turbine using a selection of materials.  The turbine had to turn when  we used a hair dryer on it and it also had to lift a plastic cup!  Lots of things to consider in their designs!

It was lovely to watch everyone interacting and taking turns to contribute.  Everyone showed consideration towards the ideas shared and compromises were made as to what the design would look like and how it would work.

It was important to try little tests now and again, to check if any changes needed to be made.  Some groups found that when the hair dryer was switched on, the blades of their turbine were not strong enough and required further reinforcement.  Some found that there blades were the wrong size or shape and some discovered that they needed to attach their cup differently so that it would lift without getting tangled in the turbine blades.  Lots of learning going on!

We tested all the designs and everyone had the chance to add their thoughts on what they thought had worked well and what could be done to improve their designs further.  I was impressed with how the children were able to make suggestions in a such a positive, caring and considerate way.  Look out world…some future engineers here!

# Time to get outdoors!

We grabbed our chalk and headed outdoors last week to show what we had been learning about telling the time!

Some helpers drew clock shapes on the playground ready for our task.  Each person gave their partner a “time” to draw on the clock face.  These varied from o’clock/half past/quarter past,/quarter times to minutes past/to the hour.  We also wrote a digital time to match, sometimes including a 24 hour clock too!

Some pupils gave their partner challenges to find things like 27 minutes after a given time.  This took a bit more thinking!

Keep having fun showing time when you are out and about P4/5/6.  Perhaps you can make a clock on the beach next time!

# Animations

During P6 Bikeability time on Monday afternoons, P4/5 have been busy working in small groups to create their own animations.  The plan was to create an animation to help children in the school learn something that they might find tricky.

Our groups are making animations showing alphabetical order, 3 Times Table, Tricky Words and Telling the Time.

We have a couple of weeks left to tweak our animations and then hopefully we can share them with you!

Some people chose to use words and pictures in their animations…

Some groups chose to use items in the classroom to make their animations…

We can’t wait to see the finished products!

# Blackout!

Today Mrs Douglas did a science experiment with the class to find out which material would work best to black out our windows during an air raid in World War 2.

We had 4 materials to choose from.  We made a hypothesis, writing down which materials would be most effective or which materials would be least effective.

Then we attached the materials to the windows and went outside to test them.  From inside the classroom , Mrs Henderson shone a torch behind each material and we had to see if any light could be seen on the other side of the window.

The red cellophane was the least effective and we were surprised to find that the light was blocked by the white paper!

# Different Ways Of Learning

We have been talking about how, for some pupils, learning times tables comes easily, whilst for others, they are really tricky to remember and recall quickly.  We looked at different learning styles today and talked about how finding a way that suits our individual learning style might just make it easier to learn these tables.  Over the past two weeks, we’ve tried out various ways to see which way we prefer.  We’ve also tried aural learning, chanting our tables to the clave rhythm.

# Outdoor Maths

We have started to explore a new area of Maths this week.  We braved the February weather to take our learning outside into the playground.  The markings on our play areas were perfect for helping us explore parallel and perpendicular lines.  We looked for right angles too.  It’s amazing how many you find when you actively go looking!

# Biosecurity

On Wednesday 5th February we enjoyed an afternoon of Biosecurity activities. Biosecurity is the protection of a species from other non-native invasive species.

We learned about the Storm Petrels on Mousa and the importance of keeping the island clear of any predators who would be a threat to them.

Afra Skene, a Biosecurity Officer in Shetland, provided lots of games and activities to get us thinking more about Biosecurity and how to spread the word to others in our community.

The children were asked to think of the ways in which they enjoyed learning and to invent activities, songs, games and challenges to try and teach others about Biosecurity. Hopefully some of our ideas will appear in a teaching resource being produced for schools in Scotland!

# Electricity

Today we looked at the next aspect of our topic  – electricity.  It was great fun exploring the electricity boxes and trying to make an electrical circuit to light the bulbs!  Lots of exciting discoveries were made  and I’m sure the hilarity could be heard throughout the school as we tried to create a complete circuit with our bodies!
