Can you build those quads?

This week’s challenge - Can you build those quads?

A lesson about muscles and skeletons? A Year 3 geometry lesson? A class visit to the local gym for a workout or a visit to the local quad centre?

Quad means four and this week my Year 3 children set off on their expedition to find out more about polygons and quadrilaterals.  The destination or key questions for the week were:

Polygon Power

Can you spot the difference between a regular polygon and an irregular polygon?
Are all regular polygons also a quadrilateral?

Meet the Quadrilateral Family

Can you describe your shape? 

Can you make your shape?

The children started the week investigating powerful polygons using a simple PowerPoint. Allowing the children to link their learning to real life examples is essential and the children explored the classroom for real life examples and doodled polygons in their maths books.

It was then time to Meet the Quadrilateral Family. I’m a big fan of anchor charts. Like an anchor, the chart holds teachers’ and children’s thoughts and ideas in place. It can be displayed as a reminder and built upon. The children can use it, for example, to access vocabulary. I make clear, simple anchor charts using PowerPoint, which focus on the main facts and then we add to these during the expedition, a bit like a guidebook. A recording is added, accessed via a QR code, for those children who find reading a challenge.

 

With the main teaching points covered, it was time to set off on their own journey. Asking children to express their ideas in a single way does not allow all children to effectively showcase what they know, so I set up different activities or places of interest for them to explore.

The more decisions the children get to make in their learning the more likely they are to be engaged and motivated. So children always have the option of taking a detour and coming up with their own activities that they think will show what they have learnt. As usual this happen during this expedition and their idea is included below.

Geoboards

In the past I would have grabbed the peg boards and elastic bands and let the children experiment making shapes. I would then spend the rest of the lesson collecting elastic bands from around the classroom as they pinged here and there! Old elastic bands would snap, and children would focus more on the colours and thickness of elastic band they craved rather than the task in hand.

But now I use an app called GeoBoards by The Maths Learning Centre. The app allows the children to make shapes using a variety of ‘elastic bands’. Once they have made the shapes, they can label the shape. The children loved this app and quickly learnt how to use it. The children could work at their own level and loved the challenge of making such shapes as the rhombus and trapezium!

ChatterPix Kids

Children benefit from different ways to express their understanding - not all children thrive expressing their ideas in writing. ChatterPix Kids is a fantastic app that allows all children to achieve, no matter what their writing ability is, and I love activities like this that engage both sides of the brain.

Each child chose a quadrilateral and then designed a new member for the family.  Photos were taken, scripts written and recorded and then stickers added. The resulting videos allowed me to assess not only if the children recognised the shape and were able to describe its properties but also their use of the correct vocabulary.

 

Shape Table

Giving children an opportunity to play is something that disappears from the curriculum as children progress through the school. So, a table full of shapes, all shapes, and sizes, provided a range of play opportunities. They were sorted, described, made into pictures. The children found some shapes tessellated and a giant honeycomb (complete with bees) appeared. Paper copies of the shapes allowed the children to explore symmetry and the children used these to create a unique set of emojis named after their shape!

Seesaw

Follow the diversion! Some children asked if they could use Seesaw to draw some pictures using quadrilaterals. They decided to use the shapes and it proved to be more challenging than they thought! There was so much discussion about which shapes could be used and those which could not. What could a trapezium become? A skirt, a lampshade, a roof, a car, the list was endless. The squeals of delight when someone discovered two trapeziums could make a hexagon!

The rucksack has now been packed ready for our final geometry expedition of the half term - straws, lollipop sticks, play dough, I wonder where this expedition is heading towards?
