The classic game of War, reimagined with meaning. Kids decode legendary Yankees into numbers, multiply against their opponent, and race to shout the answer. A print-and-play flash-card game plus a 150-problem practice workbook — four skill levels, answer keys, and a certificate. Ages 7+ · Grades 3–9.
Number Battle turns everyday facts into fast, friendly math duels. Instead of a plain "7," a card reads "Mickey Mantle." Players decode the clue into a number, multiply it against their opponent's card, and the first to shout the correct product wins the round. It builds number sense, memory, and lightning recall — and it's genuinely fun to play.
Yankee Strike is the baseball edition: thirteen collectible-style cards featuring nine numbered Yankees legends (from Billy Martin at 1 to Roger Maris at 9) plus four Wild Cards — Aaron Judge, Gerrit Cole, Anthony Volpe, and Max Fried — that add their value to your opponent's card before multiplying and can flip the whole round.
Every deck comes in four skill levels using the same cards, each revealing a little less so players lean harder on memory as they climb: Level 1 shows the number, picture, and name; Level 2 drops the number; Level 3 is picture-only; Level 4 is the name alone. Start easy and level up, or mix levels for a custom challenge that keeps everyone in the game.
The included practice workbook reinforces everything away from the table: six worksheets and 150 problems spanning multiplication match, association mix-ups, wild-card combos, a brain-buster challenge, plus Double Dash and Sums of 10 drills. Full answer keys make it easy for teachers and parents, and a printable Certificate of Completion celebrates a finished challenge.
Just print, cut, and play. Print the decks on card stock and laminate them for a set that lasts.
