Area Perimeter War

This game is an old favourite. I used to play it when I was at school! It is good as a mental maths or early finishers task. They will be working on area, perimeter, addition and multiplication, all in one game!

Area Dice Game

• A game for 2 or 3 players.
• Each player chooses a colour pencil or texta they will use in the game.
• Players take turns rolling the dice, using the numbers that they rolled to draw the perimeter of a rectangle or square & writing the area in the middle of the shape.
• Game ends when players run out of room to draw.
• Winner is the player who has used the largest area/most squares.

To make it War

When for four consecutive rolls neither person can draw an area of land that fits, WAR Begins.

Roll both dice and the perimeter of a shape with these dimension makes the distance of the bomb

The bomb is launched from that distance from your land and try on land on the oppositions land.

If successful, role the two dice again to find the area of the explosion and destroy appropriately.

AMAZE YOUR STUDENTS WITH THIS MATH MAGIC TRICK!

Posted by Brittney Field on Aug 27, 2015

Want to show off a little ‘magic’ in math class tomorrow?  Want to watch your students’ jaws drop when they see you guess their secret number correctly again and again?  Let me teach you how to do the coolest (and simplest) math trick around!

I think you’re really going to love this one.  It’s easy to prepare and so much fun to do, even as adults.  Here’s how it works:

1. Click here to download a free PDF of the Magic Math cards. Print out the Magic Math cards page and cut out each of the cards individually.

2. Place all 6 cards face-up in a pile and put the “Pick a Number Between 1 and 30” card on top.  The order of the other 5 number cards does not matter.

3. Show your student the “Pick a Number Between 1 and 30” card and ask him/her to pick a number between 1 and 30.  Be sure that the student does not tell you what it is.

4. Show the student the first number card in the pile and ask, “Is your number on this card?”  Be sure that the student looks carefully before responding.

• If the student says “yes,” make a mental note of the number in the top lefthand corner of that card (it’s either 1, 2, 4, 8, or 16).
• If the student says “no,” just continue.

5. Show the student the next number card in the pile and do the same as you did before.

6. Repeat until you have asked the student for all 5 number cards.

7. You should have kept a mental note of the top lefthand corner numbers for all of the cards to which the student responded “yes.”  Add those numbers together.

• TIP: Keep a running total in your head as you move through the cards instead of waiting until the end to add them.  It’s much easier to remember a running total than to remember a bunch of different numbers.

8. The sum that you just calculated is the student’s secret number!  Now’s the fun part – blow the student away by sharing what his/her secret number is!

How cool and simple is that trick?  You can repeat it with your students again and again, but I guarantee that they will quickly want to learn how to do it themselves…

Dominoes

IN pairs, students grab 10 dominoes and put them face down. As quickly as possible (timed by partner) student turns each domino over and adds the numbers shown. Can be used for subtraction or multiplication also.

Input and Output

Start with a number you pick and write on the board. Then come up with a rule in your head and write the result on the board.

Now leave it to students to figure out what operation you performed to come up with your result.

You can adjust this mental math activity based on the level of your students. The rule you use can be very simple, such as basic addition or subtraction or it can be more complicated, such as raising a number to an exponent or a series of operations.

For example, let’s say you begin with the number 7 and you get these results for different levels of students.

• 7 yields the result 10 (You added 3.)
• 7 yields the result 2 (You subtracted 5.)
• 7 yields the result 49 (You multiplied by 7 or raised 7 to the 2nd power.)
• 7 yields the result 121 (You multiplied by 17 then added 2.)

Fast Multiplication Facts

Do the students in your class need review of their basic multiplication facts? You may not think of multiplication facts as mental math, but each time a student is asked for a fact, he or she has to go through the following steps:

1) What fact is my teacher asking for?
2) Do I remember that fact?
3) Student pauses for a ½ second.
4) The answer to that multiplication fact is ______. I think I know the answer (and I didn’t have to use a calculator or count with my fingers or toes!)
5) Teacher, the answer to 6 x 8 = 48. I got it right!

This fun game will give kids another way to practice their facts and make their ability to provide the answers to multiplication facts more automatically.

Divide your class into teams of three and give each team a deck of cards with the face cards removed.

Give each team a number to use as a factor. They will keep that factor until they go through their entire stack of cards.

Let’s say you give the first team the factor 7 to work with. Two players will play against each other and the third member of the team will keep a record so that everything is fair and square!

Player 1 turns over the 6 of diamonds. He or she multiplies 6 times the constant factor of 7 and gets the answer 42.

Player 2 turns over the 9 of hearts. He or she multiples 9 times the constant factor of 7 and gets the answer 63.

Since Player 2 had the largest product, he or she collects all four cards for that round.

In the event of a draw, which would happen if the players turned over the same number in different suits, they simply choose again. Whoever wins that round takes all 8 cards.

The rounds continue in this fashion until all the cards in the deck are used. The player in each team who collects the most cards wins.
