SK68 clone, the one Flydiver linked above is a great example:

Note that complicated page has a lot of “bundles” associated with different descriptions at far higher prices.
If you want to make it the best for kids, then buy Energizer AA lithium primary cells. Each one costs almost as much as the flashlight — and worth it. They last a long time. They DON’T CORRODE AND LEAK and RUIN THE LIGHT. Seriously. And they work when it’s freezing cold, unlike alkaline batteries. Alkalines get very weak when it’s cold. That matters a lot, outdoors.

Yeah, there are better lights — people have suggested several. But these things are going to get traded away for something a kid wants more at the moment, lost, whatever. What costs kids nothing, they won’t hang on to — that’s how it works.
The ‘zoom’ feature is neat enough kids like that. And the lens can be just unscrewed and it becomes a very wide area light, very useful. Those features make it worth hanging on to.
Note these SK lights are going to be very inconsistent, you never know for sure what you’re getting. Look at the reviews for this one, someone actually lists many of the suppliers and what they claim they’re selling, a useful list:

ALTERNATIVE: try looking at dorcydirect.com
and contact Dorcy and ask them to offer you something good for this purpose.
There are real people there, I’ve gotten consistently good products, and the one time something failed they sent a replacement immediately. They have lots of choices. Not what the flashlight addicts will recommend, but for kids like you’re serving, several of Dorcy’s lights would be good — and consistent, reliable, predictable.
Stay with the Energizer Lithium AAs — for cold weather.
2xAA light for $4 (actually less, contact them for their discounts)
Or — go with AAA cells (also Energizer Lithium) and a simple low powered light:
(Dorcydirect always has significant discounts from list price, contact them and ask)
