For something fun, particularly directed towards grade fours and grade fives, here is Geo-math to Christmas Eve Rescue. It integrates the subject of Geometry with Social Skills and Language Arts. Specifically, it explores the formation of stars using triangles. These stars will help light the skies for Santa. First, a team of mice in Santa‘s workshop try to make a triangle with a very long stick and two far too short sticks. Cooperating, three other teams experiment using scalene, isosceles and equilateral triangles. Will they get the stars made in time?
