"The word mathematics makes many adults think of rote procedures for getting correct answers, a holdover from our own school days. But mathematics is essentially the search for sense and meaning, patterns and relationships, order and predictability." - Juanita V. Copley
"Everything around us can be better understood with mathematics. Preschool is a good time for children to become interested in counting, sorting, building shapes, measuring, and estimating." - Douglas H. Clements
MeasurementYoung children develop an intuitive notion of measurement through natural everyday experiences. They explore and discover properties such as length, height, volume, and weight as they look for a longer block, measure who is taller, pour sand from a small bucket to a larger one, or try to pick up a heavy box and ask for help. They make comparisons to see which is longer, taller, heavier, larger, or smaller. - California Preschool Curriculum Framework, Vol. 1
Inchworm Ruler to measure items by inches or inchworms.
Rulers for measuring plant growth. Print, laminate, and cut out these rulers. Use double stick tape to adhere to a paint stiring stick. Place in the soil to measure plant growth over time.
Geometry is more than just shapes…
Geometry and spatial reasoning offer a way to describe, interpret, and imagine the world.
During the preschool years, children develop a growing understanding of shape and spatial relationships. They learn the names of shapes and start to recognize the attributes of two- and three-dimensional shapes. They also develop an understanding of objects in relation to space, learning to describe an object’s location (e.g., on top, under), direction (e.g., from, up, down) and distance (e.g., near, far).
"Geometry is the study of space and shape" - Douglas H. Clements
Number sense refers to children’s concept of numbers and their relationships. It starts early on with an infant’s ability to visually recognize the number of elements in a small set and continues with children’s verbal counting, as they further develop the sense of quantity, number relationships (e.g., less than, greater than), and the fundamental understanding of addition and subtraction. - California Preschool Curriculum Framework, Vol. 1
