Here's one of the ways I have had students keep track of their nightly reading... Reading Clocks! It's very easy for kids (and their parents) to complete and eliminates the ordinary reading log. Students simply color the clock (in 5 minute increments) to equal their minutes read. It's also a great way for them to practice telling time and counting by 5's!!
I just added this to my TpT store... which as you have already read is one of my summer projects!! Tomorrow I will show you what I use now, a RAH chart!
