Get yourself a free Prowise account. Loads of gizmos (birthday songs, working board compasses, dice, spinners). Seriously, just explore.
Prowise also has a Voting system - prowise connect. Kids go to prowise page on ipads, you click on connect logo - code displayed on board.
Kids enter name and the code and then you're all able to contribute. Make mind maps ( type subject, its displated on boards kids type words, the appear on screen) they love that. (Just warn them, no emojis they dont show up. And it says [poo!] If they hit the one they insist is "Ice cream Miss!" )
You can also set questions (true/false, colours, a-e, yes/no) option on ipads, kids click theit choice it displays on board.
(These can be saved in presentation - used carefully it can be a record of formative assessment, zero additional time).
There are some fun maths races (monkeys climbing a vine, rockets taking off) where the things moves with each correct answer and they're racing each other.
Love Prowise. It's the best bits of smart and promethean software, Web based so you can create the things you need at home and access in school.
GoNoodle - again, free account. Great for a 'brain break' Last year's class loved the Zumba Kids, pop-se-ko and DiscoBrain. This year we're more into secret handshakes and trolls. They love it, and it's a 2-3 minute video that gets them up and moving and they'll do almost anything to be allowed to choose a video! (Last year my class had adult supervision on indoor plays - Indoor recess videos were amazing. I got my coffee, they got 13 minutes of jumping, dancing, running on the spot. Came back to a much more settled class than after 15 minutes of drawing/reading/ being bored. I don't allow it without adult presence though. )
Also very easy to build a presentation in SmartNotebook. Use shapes to hide answer so they can self check (change colour to match background if you want to do a 'reveal' yourself while talking.)
Display a model piece of work. Have kids annotate it (best for writing) using different colours for different aspects (red= topic sentences, green = connectives, etc)
Not a smartboard thing, but my noisy/chatty class adore "the secret person" - I choose a random person (class dojo randomiser). If that person is working and behaving well for their 90min slot, the whole class gets a teamwork dojo. (I might add a 'secret person' category) we all cheer, person gets a Sticker. If person broke a rule, was too loud, didn't work I just say, "Our secret person didn't make good choices " reiterate expectations. I don't name unsuccessful secret people.
