Triangles, rectangles and squares, oh my!

Today we are continuing our exploration of 2D shapes by looking at squares Using the same goals we have been using all week:

The language and features of different shapes.

The name and features of different 2d shapes.

Be able to do:
Explore geometric features and describe shapes using vocabulary such as ‘sides’, ‘corners’, ‘edges’ and ‘faces’.

I want to see if the students can tell me what is so special about squares so I posed them this question.

As you can see, this is a class of very clever cookies!

As a way for the students to physically create the shapes we have been investigating, I gave them some marshmallows, toothpicks, matchsticks (without the heads of course!) and BBQ skewers. We agreed that the marshmallows represented the vertices and the sticks represented the sides.

The students did a very good job of demonstrating their understandings of the features of the shapes through their constructions. AND they all showed incredible restraint by not eating the marshmallows. What a great class!

When they had finished making a square, rectangle, triangle, pentagon and hexagon, they got onto their iPads and started making patterns and shapes using geoboard on their ipad. There are some very creative students in my class.

At the end of the lesson the students reflected on their learning this week.

Today I learnt that a square is a type of rectangle.

– Mr V.

Today I learnt how to make squares and triangles out of marshmallows.

– Miss K.

This week I learnt what a pentagon is. (It’s a house shape – it has 5 vertices and 5 sides)

– Mr A.

This week I learnt about 2D shapes.

– Miss A

I can’t wait to start investigating 3D shapes next week.
