# Pre-Algebra Games and Fun

## Triangle Math

## Middleschool Math and Pre-Algebra

As a final step before Algebra, children are taught fractions, percents, decimals and ratios while perfecting their grasp of the four operations, addition, subtraction, multiplication and division. This mastery of the four operations is what makes the higher levels of math turn into fun puzzles and intriguing patterns of numbers that can explain the universe.

This article will give you an overview of math taught in K-8 as preparation for High School Algebra with an emphasis on games and activities that will help children in 4-8 grades solidify their understanding of pre-algebra concepts while playing fun and challenging games. Come roll the dice and shuffle the cards. It's time for pre-algebra fun...

## Alternatives to Math Textbooks

Of course you could use textbooks. There are many out there and you will be assured of covering all of the subjects thoroughly. However, if you are brave and have confidence in yourself and you child, there are many more exciting ways to learn all the math skills to prepare for algebra lessons.

We homeschooled our oldest until she started 7th grade. When she entered public school for the first time she was beginning Algebra II. The following are materials that we used and found most helpful for learning pre-Algebra.

## Number Sense - What do those number really mean?

Number Sense is understanding what numbers mean. From beginning levels where the number 5 represents five fingers to fractions where 1/4 means that there is one out of four and on to understanding that 2-5=3 does not make sense. This is the beginning of number sense. It is also understanding that 56 is a smaller amount than 65 and that 1/2 is the same as .5. All of these concepts are needed in order to begin to study algebra and there are games that you can play with your child to learn each one of these concepts.

## Teaching Number Sense

## Play finger games with your child

Despite all that you have learned up until now, counting on fingers is a good thing.

- Ask your child to hold up two fingers.
- Now take away five of them.
- It can't be done! It is time to go back and look at the problem again. Was the problem really 5-2 rather than 2-5?
- That is a difficult concept for 6 and 7 year olds but with repetition they certainly get it by the time they are ready for algebra.

Most textbooks stop there but I have found that it makes more sense to continue on and explain negative numbers to your child.

- Ask your child how many people will be eating at your table for the next meal. (Let's say 5)
- Hand him or her items to be placed on the table.
- 4 plates. You need 5. I gave you 4. How many more do you need? One!
- You have negative one plates.

- Hand your child 3 forks.
- Once they have placed those three forks they can be taught the terms that they now have negative 2 forks or that 2 more forks are needed.

Your child is learning the terms that will prepare them to understand algebra.

We started playing finger games when the kids were young. Wherever we were we counted, added, multiplied and figured out problems. It was always fun and it wasn't long before the kids were making up their own problems.

## Hi Ho a Cherry O

## Games that teach Number Sense - Number Sense builds skills needed for learning Algebra

Board games are great for teaching number sense. Counting backward and forward, moving spaces, skipping ten, going back two on the board helps children understand the relationship between numbers.

Snakes and Ladders, Rack-O, Go to the Head of the Class, Hi Ho a Cherry O and Monopoly are just a few of the games that teach children number sense while having lots of fun and family time.

A good sense of just what numbers mean is vital when beginning algebra.

## Snakes and Ladders

## Mancala

At first it might seem that Mancala is just a simple counting game. Very young children can quickly begin to play successfully.

But as with many good games the more you play the more math is involved, the more patterns you notice and you start applying strategies to your game.

Usually we begin with three beans in each pod.

- What happens when you begin in different places?
- Does it matter who begins the game?
- How does your strategy change when you start with 4, 5 or more beans in each pod?

Mancala can involve strategy and complex higher math, putting it on par with chess and similar strategy board games.

## Playing Mancala

## Four Operations on the Hundreds Board

Learn the Four Operations with this variation on the Hundreds Board. Tom DeRosa from the I Want to Teach Forever Blog tells us that The Sequence Numbers Game allows students to practice addition and subtraction number facts in the context of an easy to learn game.

- The game goes like this: each player/team has a handful of these number facts cards.
- The game board, as you can see in the picture, has color-coded numbers that match the cards.
- Each turn, you can put one of your chips on the answer to one of the cards in your hand.
- The object is to get five chips in a row..

This game would be a wonderful addition to any classroom or homeschool family's game closet.

## Adding and Subtracting with Parcheese

## Board Games teach Arithmetic

One of our favorite board games is Parcheesi.

- Roll the dice and count the dots (One to one correspondence)
- Add the two numbers together (Addition)
- Move your playing piece that number of spaces. (Counting)
- Notice how many more spaces are needed to get around the board. (Subtraction)
- You have to get the correct number to get into the home space. (Addition and Subtraction)

As the kids get more and more proficient with the board it is fun to look for more and more math.

- How many spaces are there between circles?
- How many spaces are there to get all around the board?
- Each person needs to move all four of their pawns around the board. Multiply to see how many spaces to get all four around the board.
- How many different geometric shapes can you find on the board?

## Add, Subtract, Multiply and Divide - You must know the Four Operations before beginning Algebra!

Unless you can answer this question with yes, quickly and easily, your child should be playing more games.

Only with a quick, fluent sense of numbers and how to add, subtract, multiply and divide will your child be ready for learning algebra. But this is where the fun begins.

## Learning to Multiply with Yahtzee

## Roll the Dice and Multiply

We always have a pair of dice on the dining room table. If we are in a hurry we might just each take a turn rolling the dice, multiplying the two and cheering the one with the highest number.

Sometimes we will add the two dice, subtract the higher from the lower number, or see if we can roll doubles.

When we have more time, we like to play Yahtzee. Yahtzee involves addition, subtraction and multiplication.

Once the kids were getting proficient we started playing 24 Game. We first learned the game as a board game but one day we decided to try playing it with just 4 dice. Of course, sometimes you can't get to 24 but that just makes the game more fun.

## Game 24

## Add, Subtract, Multiply and Divide with the 24 Game

Use the four numbers around the card to add, subtract, multiply and divide to get to 24. The first one to get to 24 wins that card.

Playing this game is not only fun, but helps your children master the four operations of addition, subtraction, multiplication and division. It is a game that can be played by children and adults. You might be surprised at how much fun it is playing games like 24 and not even realize that you are preparing to learn Algebra.

## Algebra in the Concrete

Mary Laycock found a way to show algebra in a fun and exciting, hands-on way that excites kids to play with first year algebra. My 10 year old homeschooler loved using the Cuisenaire Rods to work out the problems while discovering the relationships between the different parts of equations. She quickly learned to make up her own problems. I wish I knew of a good sequel.

This book was enacted by a group of upper elementary school children as they built the sequences, algebraic expressions, rectangular arrays, and equations of elementary algebra.

Pictures of their work are included so you and your students can see how many different types of manipulatives can be used in constructing some of the fundamental concepts of algebra. Added activities include factoring trinomials to solving quadratics.
