Tie a bead (I use a different kind bead so it's obvious) as a stopper to one end of your string/elastic thread).
Add 4 beads (or any even number beads) to the string.
Note: If you use an odd number beads the pattern will not work out, there is a way to weave with an odd number, but it's a bit more difficult and can be confusing for beginners or young children. You can use any even number, for a bracelet, this will define the width of your bracelet, 4 is a pretty good size for kids arms. You can use this technique for any size projects, 12-16 beads for coasters, or even 50 beads or more for placemats.
Add another bead and put the string through the 3rd bead of the first row.
Add one bead and put the string through the first bead of the first row.
(You can totally do Step 2&3 in one step, I just separated it for clarity, this is how the kids I did this with understood)
Pull tight. Now you have the basic set-up for the weave pattern.
1-2-1-2 or low-high-low-high.
Add a new bead at the low position and pull the string through the blue bead (high) of the last row. Repeat.
Got it? Always add a bead to the low position and pull string through the high of the last row. For a 4 bead wide bracelet you will add 2 beads with each row, switching direction from left-right to right-left and back...
It's much easier and quicker to do this with a needle, as you can see in the picture to the left.
You should pull tight after every row, but you can loosen up the last row a bit to make it easier to put the string through the beads, this is especially helpful if you (or your kids) do this without a needle.
