Pre-math skills (referred to in British English as pre-maths skills) are math skills learned by preschoolers and kindergarten students, including learning to count numbers (usually from 1 to 10 but occasionally including 0), learning the proper sequencing of numbers, learning to determine which shapes are bigger or smaller, and learning to count objects on a screen or book.
Preliminary math skills involve learning to count numbers (1-10), recognizing shape order, determining size comparisons, and counting objects in visual aids like books or screens.
