Use flashcards to teach your kids math with Talking Math, a utilitarian educational tool that speaks the answer aloud to the math problems it presents. While it's not the most polished of programs, it works well and there are a few options for how to use the flashcards. And even though it's free, you won't be hit with any ads.
Talking Math takes up the whole screen when you launch it, although a huge strip of black outlines the actual interface. A flashcard appears automatically on the screen, with a prompt to click it to begin. You can choose one of three modes from the left sidebar: Standard, Interactive, and Timer. Each is easy to follow, although we preferred interactive flashcards, which lets you choose answers, while the standard mode showed the card and the only option was to click the card to hear the answer in the standard Microsoft Anna voice. With one click you can change the cards from addition to multiplication, division, or subtraction. There was little on offer here that you couldn't get with an actual set of flashcards, but Talking Math works well and it's very easy to operate.
Talking Math's rudimentary design doesn't take away from how well it works. If you're trying to teach kids math basics, then this is an ad-free, no-cost tool that can help.
