Creating Our Own Polygons

[youtube]https://www.youtube.com/watch?v=TbR_rakilds[/youtube]  [youtube]https://www.youtube.com/watch?v=yVgP3AZCfdU[/youtube] This morning the children continued exploring polygons and their attributes.  They enjoyed listening to two songs that we watched on YouTube at the start of our working period.  Their task today was to create a polygon with more than 4 sides and draw it onto their geoboard paper.  Once they completed this part, they […]

Exploring Our Knowledge of 2-D Shapes

  [youtube]https://www.youtube.com/watch?v=aE0yle-z5uE[/youtube] (Video taken from YouTube) Ms. Claire joined us last Friday for a read aloud that got us thinking about shapes we know and their attributes.  The children explored their prior knowledge of some shapes they already know and worked together to create a list of specific attributes about the different shapes.  The enjoy […]

What Do You See?

We had an exhilarating learning time this afternoon as we explored the image above.  The children were engaged and eager to share their ideas of what they saw.  After we brainstormed what they saw and all agreeing they saw squares,  the children then went off to work in pairs to see if they could come […]

Tuning In: What is Geometry?

This week we launched our new math unit ‘Geometry‘?  To find out what the children already know we complied a splash of ideas that come to their minds when they hear or think of the word geometry.  Above you will find the Spy Ninja’s ideas.  Followed by this discussion and share time, the children then […]

Polygons

Students have been inquiring and exploring what geometry is all about.  We’ve had discussions about 2D and 3D shapes.  After reading the story “The Greedy Triangle,” (see the links below) students created their  polygons using geoboards and rubber bands. Students were quite creative with the pentagons, hexagons and heptagons they made. They  had to count […]

Glorious Geometry

Last week, we read The Greedy Triangle by Marilyn Burns. After listening to the story, the children made the different polygons from the story using geoboards and elastics. After that they recorded each polygon on geoboard paper, labeled it and showed its angles. Here are some of the vocabulary words we have discussed and been […]

Geometry Project December, 2012.

The students are noticing all the different shapes that make up the buildings that surround us. In spite of the complexity of some buildings, the students can recognise and identify the simple basic shapes and angles that make up the structures. Some students can explain the safety aspects of constructing buildings that are safe and durable, as well as […]

fancy professor words unfold in geometry class…

When is a line segment NOT a line segment?? What is a ray?? Should we actually be saying to the class “everybody, walk in a straight line SEGMENT” (not LINE)??!!

Going..going…gone!! Decimals make way for geometry!

It was a short unit as it followed on the tail of fractions, which followed on the tail of division (see the connection?!!). We used visuals, we played games and we practised the concepts using place value manipulatives. Imagine word study fitting in to math?? Of course… add the suffix –th and you instantly have […]
