This week we have been learning about the properties of 2D shapes, using words such as vertices, sides, regular and irregular. The children conducted an investigation using lolly sticks. The aim was to make a pattern of triangles, and then develop a formula for how many more sticks each row would require. E.g. 1st row needs 3 sticks, 2nd row needs 6 more, then 3rd row needs 9 more…

The children really enjoyed the practical aspects of this activity and collaborated well. Lots of mathematical discussion taking place!
