Addition is relatively simple, but tedious. You need a systematic repetitive approach to ensure accuracy.

Here's Superhero Mom explaining conventional addition to 'not-so-enthusiastic' Junior. (We've all been there, right?) 

	Write down one value (addend), say 16.67%. (Junior replies: Okay...)
	Write the second value, say 33.33%, below. Align the columns (tens with tens, units with units, and so on), and the decimal points. Then draw a line below. (Mom, what's the point?) Junior, stop it!
	Start with the first column on the right. Add the two units together. (But what are units?)
	If the total is 9 or less, write it on the total line in the units column. (Mom, I need a drink!)

And the saga continues....

If the total is 10 or more, write the units in the units column in the total line, and 'carry' the tens digit over to the tens column. (What do you mean 'carry'?) Repeat this process for the tens column. Don't forget to include any tens 'carried over' from the units column addition. (Mom, I don't get it...) Repeat this process for the hundreds column (if any), etc. (Mom, can we stop, please?)

"This is relatively simple, but it does sound complex, doesn't it?" 

Of course it isn't complex, but there are many steps and lots of opportunities for error. You must pay attention to detail or risk making mistakes!

In fact conventional addition challenges many kids and adults. And while you focus on process, you can easily miss the basic principles involved.

Traditionally math is taught using spoken and written language. Notice just how much language is needed above. So good readers and writers have immediate and lasting advantages in math over their less literate peers.

Often language and process are so demanding that they prevent true understanding, especially of abstract math concepts.

Now let's see a simpler visual method using the Pizza Pursuits cards.

"Here's how you can add percentages without using math - visually!"

Here are two cards, one valued at 33.33% (1/3rd) and one valued at 16.67% (1/6th) that together total 50% (1/2).

The visual addition process is simple and intuitive:

Overlap and offset the two cards. Align two tags, one from each card end-to-end. Align the start of the second tag with the end of the first tag. Read the total percentage on the measure on the overlapped card.

You can total a complete hand of cards in this way too. Just overlap and offset each successive card and align all tags end-to-end in a row. Use the end of the last tag to read the total value on the first card measure. 

"Visual addition is so simple, that even a child can do it!"

The above example uses percentage values. It works in exactly the same way for decimals, fractions and degree values too!

	Not convinced? Try explaining how to add 1/3 + 1/6 using conventional math to your kids.
	Or adding mixed measurement system values together such as 33.33% + 1/6, or 0.3333 + 60°, etc.
	And you can add two groups of cards together just as easily. For example, add group A (1/12 + 1/6), to group B (1/12 + 1/5 + 1/20) and group C (1/12 + 1/20).
	Use visual math to subtract individual cards or groups too!

Okay, these are just a few examples of the power of the Pizza Pursuit cards. But you really need to experience visual math for yourself. You can immediately 'see' answers that elude you with conventional math. It's like someone drew open a curtain that prevented you from 'getting it' before.

You know a good physical workout stretches, exercises your body and builds physical fitness. Similarly, a good mental math workout stretches, exercises your brain and builds brain power. Playing card game tactics, strategies and play help develop and build intellectual power also.

Pizza Pursuits is a powerful fun-filled mental workout for your family. It could help develop your children and give them a competitive advantage in life.

Enjoy!
