Anyone just getting into astronomy (especially kids) should have a good starter telescope that won't break the bank before they've decided whether or not this is the hobby for them. Celestron's 76mm FirstScope Telescope is what I'd recommend.

It's got a nice wide field of view, decent-enough optics to view Jupiter and Saturn in the right conditions — although you probably won't be able to make out the former's bands or the latter's rings without upgrading either of the included eyepieces and/or adding a 2x Barlow extension — plus it's super lightweight and portable.

Additionally, the Dobsonian-style rotating tabletop stand lets you adjust your viewing angle with ease, and the optical tube is marked with the names of many of history's most notable astronomers and scientists.
