More About This Title When Points Meet Lines


When points meet lines and extend on into space, some fascinating forms take shape: circles and spheres and cylinders, triangles and cones, squares and cubes, among others. A pizza can be a delicious circle. An arrowhead is shaped like a triangle. A five-dollar bill is a rectangle. There are many interesting shapes, whether visible or hidden, to discover in the world around us. Hands-on activities and elementary math concepts relate shapes and space as well as help little ones name and understand both flat and three-dimensional shapes, turning simple geometry into brain-teasing fun.
