Less than greater than

I am periodically going over < and > with Megan.  She did a page of this with various numbers from in the tens place, 19 -90 was the range of numbers compared. I am teaching her that the tens place is used at first, but if this place value is the same, say 23 and 29, then the units place determine which number is bigger. Did page 198 in complete book of numbers and counting.  She also practiced writing " eight" .
