I created this Valentine's Day Math pack for my kindergartners. It includes printables in color (to laminate for centers) as well as black and white for individual copies. Enjoy!
-- Addition and Subtraction (to 10) worksheet with hearts to use as manipulative. (in color and black/white)
-- A roll and record game--students roll a die or dice and cover that # of hearts with a counter or cube. Student who covers the most hearts is the winner. (best played in partners with each student getting a designated color counter)
--- Measuring activities (both standard and nonstandard units of measurement)
--- Story problems (addition and subtraction within 10) & a page of hearts to use as manipulatives--4 strips of 10
