My kinders loved playing this game and I know yours will, too! It's a simple game that provides great practice with comparing numbers as well as with left and right awareness.
Number cards can be printed in black and white or color. One player is "left" and one player is "right". As they pick their cards for each match, they write the number on their side of the heart. When the numbers are compared, the player with the greater (of lesser) numeral circles their number. When the hearts have all been filled, the players count the circles on their side and compare to determine the winner.
