He has tried showing the student a number line, an open number line, a chart, and a rounding rap. He even wrote the steps down for the student. The student doesn't understand how to find the benchmark numbers for the problem. Mr. Davis tried to help the student with skip counting but that still doesn't help. For example, the rounding number is 36 to the nearest ten. The student doesn't understand that 36 is between 30 and 40. What's next? Solution: (Rates are posted for this solution!) My students love the phrase "5 or more, raise the score. 4 or less, let it rest." Another suggestion is putting the number line on the floor and having students walk it out. Or, you could make a curved number line on a table and give students a car. Pretend the number line is a mountain or hill and ask students if they'd roll back or roll forward. You could also make a human number line. Have each student in the number line hold a number. Give a student a number to round and ask the student which student their number is closest too.
