Recently my friend Amy Climer designed a set of picture cards with images she hand painted. Amy did the legwork to get her creation manufactured into a standard size deck (She funded this project finding supporters with Kickstarter - a wonderful crowd sourced fundraising tool.)
What I love about Amy's deck is it's versatility. First and foremost I can use the picture sides of the Climer Cards with all the activities in The Chiji Guidebook - this gives me the variety I need for the groups I work with multiple times. Using the "other" side of the cards I can sort large groups. "In the deck of 50 cards," Amy details, "are 5 different shapes (groups of 10), 10 numbers (groups of 5), and 6 colors (groups of 8 to 9). The Climber Cards are a powerful pocket-sized tool I highly recommend. Visit Amy's website for details on how you can pick up a deck.
All the best, Chris
