2D Marshmallow shapes



This week as part of our Maths we are exploring shape. We made lots of different 2D shapes from cocktail sticks, straws and marshmallows. The shapes we made were
  • Triangle (3 marshmallows + 3 cocktail sticks)
  • Square (4 marshmallows + 4 cocktail sticks)
  • Rectangle (4 marshmallows + 2 cocktail sticks + 2 straws)
  • Pentagon (5 marshmallows + 5 cocktail sticks)
  • Hexagon (6 marshmallows + 6 cocktail sticks)
  • Octagon (8 marshmallows + 8 cocktail sticks)
When we were finished we counted the total number of corners (marshmallows) in all the shapes. There were 45 altogether so each child got 2 each and one was left for teacher!
(22X2) + 1 = 45 marshmallows
Who ever said that maths was not delicious!
