This is how to crack those tables, Flipguarder!
(Keep page 126 of the DMG open while reading this)
During your groups first level adventures, your heroes are supposed to get everything listed under the "Party Level 1" table. This table lists ten treasure "parcels" but that's only a different name for "helpings" or "portions". You certainly don't have to hand out treasure exactly ten times during this level (level 1) - you could save up all ten parcels for when they complete the adventure and give it all out then, if you like.
Okay, so what do they get then. Two things, magic items and money.
Money's easy. That's the gold, art objects and what have you. The table splits it up over six or seven "parcels" but it does also add up the total for your convenience. The "Total monetary treasure" in the table's header, upper right, essentially says "During first level, hand out 720 gold". That's in total, not per character. And it assumes five PCs.
Magic items then. You won't see specific suggestions (like +1 Flaming Longswords), only generic listings such as "Magic item, level 2". This means you the DM (or the adventure designer) needs to select an item appropriate (or not so appropriate) for the group. This could be a sword, an amulet, a holy symbol or anything really. Just as long as it is of the listed level.
Unlike previous editions, 4E doesn't use random generation, as that's only likely to yield stuff your PCs can't use and will be forced to sell. With sale prices being only one fifth of the market price, this won't be nearly as attractive as keeping the item. Assuming someone in the party can use it. In other words, which items and whether they're usable or not is a decision that's entirely up to you as the DM. Not random tables.
Okay, back to the table. Remember we're level 1 here.
If we total the table we get the following:
One level 5 item
One level 4 item
One level 3 item
One level 2 item
...and gold and stuff worth 720 gp.
This is the answer to "what am I supposed to award a team throughout level 1".
Then, the party becomes level 2. And we repeat the same procedure again: decide where and when the party finds treasure, and decide exactly what the four items will be.
You will note that all these tables follow a specific pattern. You get four items (of your level+4, level+3, level+2, and level+1) plus gold equal to the market price of two items of your level.
Let's take level 4 as an example. You get one item of levels 8, 7, 6, and 5, as well as 1680 gp's worth of gold, potions and other stuff. 1680 is exactly double the market price of any fourth level item (840 gp). Check out the table on page 223 of the PHB to confirm this for yourself!
So, again, what should a lvl 5 party of 5 people have in total?
Assuming they started out at first level, and levelled up normally, and they just reached their new level, they should have:
Everything from the "Party Level 1" table (again, page 126 of the DMG)
plus everything from the "Party Level 2" table
plus everything from the "Party Level 3" table
plus everything from the "Party Level 4" table.
Which, if we add it up, I'm sure we reach the summary listed above by Syrsuro.
