In this next picture my kid pointed to the triangle, but her pencil drew a line to the square. She shook her head no. I erased it. She did the same thing again. I erased it and told her to move on before she got stuck on it. It's a line drawn from lower right corner to upper left corner, tricky. Like x is a trickier letter once you start letters.
