War Activeness For Practicing Absolute Value, Opposite, Reciprocal, Together With Contrary Reciprocal

I powerfulness convey went a fleck crazy when I started making activities for our starting fourth dimension science of the twelvemonth inwards Algebra 1. So, you'll convey to pose upward amongst quite a few posts involving activities for practicing absolute value, opposite, reciprocal, in addition to reverse reciprocal.

Today, I desire to portion a nation of war activity I created. My sis in addition to I loved playing nation of war when nosotros were kids. Most games weren't that exciting. Whoever had the most aces almost ever won. But, in that location was merely something exciting virtually throwing downward a menu to meet whose menu had the highest value.

While the traditional menu game is exclusively played amongst 2 people, this do activity tin plow over the sack function amongst two, three, or fifty-fifty iv students inwards a group. Each grouping gets a laid upward of cards. The cards are printed on 2 dissimilar colors of newspaper in addition to laminated.

The yellowish cards are criteria cards. There are xv cards. Three each of 5 types: original number, absolute value, opposite, reciprocal, in addition to reverse reciprocal.

The criteria cards larn shuffled in addition to placed inwards the pump of the playing area. The residuum of the cards are distributed evenly according to the unwrap of players.

The transcend menu on the deck of criteria cards is turned over. This menu tells the players how the winner volition endure decided. The histrion whose original unwrap is the greatest volition win. Original unwrap is the easiest because students don't convey to create anything to their numbers to determine the winner.

Each histrion turns over the transcend menu on their deck.

8 is the highest original number, in addition to then the other 2 players plow over their cards to the histrion who had 8. These cards are placed on the bottom of the winner's stack.

Now, let's modify the criteria menu in addition to flip over some novel numbers. This time, students convey to uncovering the reverse reciprocal of their numbers.

1/3's reverse reciprocal is negative piece the others are positive, in addition to then that histrion doesn't win. 1/3 > 1/8, in addition to then the face-up cards are given to the histrion amongst -3.

Up next: Opposite

The reverse of -7 is vii which is the highest value of whatsoever of the opposites (7, 6, 1/4).

Next Round: Absolute Value

My students actually enjoyed this game! They had quite a fleck of problem comparison fractions to determine which was larger. I spent a lot of fourth dimension going roughly in addition to helping students figure out which values were bigger when fractions were involved. This is something they should convey mastered inwards middle school, but we'll merely convey to proceed practicing comparison numbers until they larn it!

Here are a few activity shots:
