Rounding

February 20, 2020

Today we looked at a number line strategy for rounding. Here we are rounding to the nearest 100. We count by 100s until we find the 2 “100s” that sandwich the number we’ve got. Here we have the number 573. We count up and sandwich 573 between 500 and 600. We make a number line, and mark the center of the interval (550), and then we place our fraction, and look at which end it’s closest to. We would round 573 to 600 since it is the closest 100.
