Hi, in order to get the most out of the hour and not get distracted I would map time slots to activities in blocks of 10 minutes and carefully focus for that entire time for example trills are very beneficial and one of pebbers recommendations is to start with about 2 minutes of time per string. I think spiders and ladders are good for warming up and ensuring that you have correct teqnique do 10 minutes of those. Then do 30 minutes of scales in G in all positions repeat 5x with no mistakes including intervals - this will extend the ladders but also be musical for example using 6ths the sequence would be 16,27,38 etc all the way up and down the position. Do some arpeggios, do some chord work, the point is to make sure that you have a plan for what you need to improve and not get distracted 1/2 through by flaking out and playing hendrix. Then save some time at the end to jam with a backing track while you are hot - that is your reward.
The point is to have a plan, and stick to it what is in that plan is really up to you and your teacher.
Also do not play too fast, set the metronome and play everything correctly at whatever speed you can handle so that you an concentrate on what you are doing. Use the trills to develop speed and strength until you know the fretboard.
Learning songs is important too, use some tabs to help you focus and pick 2 songs per week to work on 10 minutes each per day repeating 5 - 10 times playing correctly.
If you do these things you will improve on what it is that you practice.
Set you goals for the week and make a video as if it is a lesson with your teacher where you play everything that you have been practicing, you can use these to review your progress in the future.
