This is an anchor chart that helps students visually see the rules for adding and subtracting positive and negative numbers. It creates a relationship between numbers that are red cards (hearts and diamonds) and positive numbers and numbers that are black cards(spades and clubs) and negative numbers. Kids will see the outcome more clearly.
Follow up activity: Students can shuffle a deck of cards and play with a partner after the chart is explained. Students can work in pairs and pick two cards per turn. Add or Subtract based on what cards are drawn. Play for High score or just for a certain amount of time.
