To use these cards I recommend printing multiple pages to one sheet of paper.
There are several different ways to use/play this game.
The first way to play this game would be “memory style”. For this style you need the umbrella cards and either the numeral (yellow boots) or number word (blue boots) cards. Lay the umbrella cards and one set of boot cards face down on the table. Each player takes a turn flipping over 2 cards and trying to make a match. The player with the most matches at the end wins.
This same game can also be played using both sets of boot cards to match numeral and number words.
They can also be used as an independent/center activity. For this you stack one (or all) set of cards face down, then pull a card and either draw, write or read the number shown on the card.
