Cutting Board Fix?

I made two cutting boards and apparently I did a bad job cutting it or the wood was too roughly cut or something, I don't know, but now they both have gaps in them. I glued one up, and the other one I didn't but could tell it was going to be the same. Is there any way to fix my goof, or if there is not, what is another project that I could use the wood for as to not completely waste it? Thanks!

Did you use a table saw to cut these? If you did then you need a better blade, a new carbide tip blade with lots of teeth, not a rough cut blade. Lower the blade so its comes only a little out of the wood and like Josehf Murchison says don't move your hands when you run the wood through the saw past the fence. You will need to cut both sides to trim them down and get them flat. Take off just a little at a time and make several passes. If you are not using a table saw then it will be extremely difficult to get flat cuts.
It is also possible that your wood might warp after the first few rough cuts. Wood is a dynamic medium and it can change even as you work it.

Do not sand the edges where you are going to join it, just trim it up with a fine tooth blade.

Another thing, be sure to use a push stick when moving it through the blade and put some pressure on it in the direction of the fence so it stays against it. They make these feather board things that are designed to hold the wood against the fence as it moves past the blade if that is a big problem for you.

By the way, the reasons for needing a sharp blade are several. One is that a dull blade tends to shred or tear rather than cut so you get ragged edges. For rough cutting that doesn't matter but for fine work it makes a difference. More teeth on a blade means it makes more cuts which gives you a smoother surface with less teeth marks.
The second reason for a sharp blade is that a dull blade will sometimes vibrate while its cutting, like a bell ringing. This causes the teeth to move from side to side and it cuts out more than it should. I have seen mine make cuts that are twice the width of the blade because of that. if the blade starts to vibrate, and you will notice it, stop your cut and allow the blade to settle down before you push more wood into it.
Although it would take some time, you could file it down, check the piece against the piece where it will be placed, and file it down some more. It will be slow and boring, but it would be with tools you probably already have.
You should have jointed all the pieces - planed them flat on the joining face- after sawing them.
I have seen this before

Here you were cutting short pieces and you moved your hands when they were near the blade during the cut.

Bad cuts can be cured by re cutting down the seams.

Use a cutting guide and if you must use short pieces hold the pieces so you don’t move your hands at the end or beginning of the cut.

Do not move your feet or hands while cutting, you will be surprised at how much even shifting your weight from one foot to the other can mess up a cut.

Wood filler is not good on a cutting board.

Fill the gaps with sawdust and glue or rent a plainer so you can square up the endges allowing them to fit together better.
