Wrong port
By default, your motors must be connected to ports A and B. So, if your robot is not moving, the first place you must look at is the ports. Do the cable connections correspond to the ports selected on the move block in the programming software?
Cable is not reliably connected
Push the cable up until you hear a "click" sound. So, if the ports are correct, check the cable connections in the ports.
A way to demonstrate to someone that the cable is not reliably connected is to shake the robot, and the cable will come out of the port.

Level A1 - Space Adventure - Robotics with LEGO SPIKE Prime
That is the first level of the LEGO robotics curriculum for second, third, and fourth-grade students.
A "space adventure" but with robots. Different robot structures are built in Level A1. The motors are controlled so that the robots perform precise movements around the "Earth", "Moon" and "Sun". We use the force sensor to overcome various obstacles we bump into. We learn interesting facts about the solar system and space vehicles.
