Anchor charts that are given to us can be confusing, so I created my own! These print 2 per sheet and come with the directions in how to round to 10s, 100s, and 1000s, but can also be used to show that no matter what value place is being rounded, the rules still apply. We use the underline and circle method, because the underline shows which value spot needs to be rounded and the circle shows which number will turn into a zero (and all remaining value spots to the right of our underlined number)
