Just updated my blog post Math Game: War with Special Decks to add a game I missed the first time around:

**Julie Morgan’s Simultaneous Equations War**

Simultaneous Equations War Cards

Math War is the most worksheety of all the math games I play with kids. But you can add a level of choice by playing the Trumps version.

**Math War Trumps:** Instead of playing for the highest sum, as in Julie’s original game, have each player draw 3 cards. The player whose turn it is first names “X” or “Y” as trump, then all players lay down a card. Highest trump value wins the skirmish.

**Variation:** Let the player naming trump also decide whether the highest or lowest value will win.
