Adding and Subtracting Integers Unit Grade 7 Math 5 Days Tools ...

Lesson: Students will practice adding integers by playing addition math warTime: 45 minutesObjectives:• The students will be able to add integers using the rules that they have created.Materials:• Deck of playing cards, for each pair of studentsActivities:1. On the board will be the following problem of the Day, for the students tocomplete as they sit down (5 min).• Sally was on floor two in an elevator. She needs to go done 6more floors to get off. What floor did she get off at?• We will go over the Problem of the Day.2. We will review the rules that we created for adding and subtractingintegers.3. We will play Addition Math War.• Each pair of students will be given a deck of playing cards.Each student in the pair will be dealt half of the cards. The redcards are negative integers. The black cards are positiveintegers. The A = 1, the number cards are equal to theirnumber, J = 11, Q = 12, and K = 13. To play each player turnsover their top two cards and adds them together. Whoever hasthe larger total points wins all the cards. If the total is equalthan there is a war and another card is flipped over and addedto their previous total until someone has a greater value.Whoever has the larger total wins all the cards. The game isplayed until someone wins all the cards.Closure:For a better understanding of adding and subtracting integers we will discuss thesimilarities between positive numbers and addition signs and negative numbers andsubtraction. I will make sure that every student understands that - - = + .Homework:NoneStudent Handouts:None23
