Text Tool for Sketch?

I’m wondering if there is a text tool for sketch? I’m wanting my kids to give an example of a “slope triangle” and writing on the slide with the pencil using a trackpad is kinda ludicrous.

Here is a quick demo of how students could enter an equation into the sketch.
Entering straight text, you could use input rather than expression input.

Sorry, currently no native text tool. Workarounds like above are an option.
