Veintiuno – Integer Card Game | Adding & Subtracting Integers | Classroom Math Game

Bring integers to life with Veintiuno (21) — a fast-paced, strategy-filled card game your students will beg to play again! This classroom-friendly math game helps students practice adding and subtracting integers, building number sense, and strategically choosing card combinations to reach a total of exactly 21.

Perfect for 6th–8th grade math, intervention groups, centers, small-group instruction, or a fun Friday game day.

⭐ How the Game Works

Students are dealt 4 cards and take turns drawing from the deck or the discard pile while trying to build a hand that totals 21.
Direction cards add a fun twist — players may swap cards, skip turns, draw extra cards, or even send someone back to the start!

The game ends when a player reaches 21, or if the deck runs out, the player closest to 21 wins.

Easy to teach, quick to play, and highly engaging!
