Grade 4 rounding to nearest 10, 100, 1000.

Stage 1- Student uses a number line to visually see if the number given is closer to 0 or 10. Student needs visuals to round numbers to nearest 10, working up to 50.

Stage 2- Student uses a rounding poem or song or “rule” to round numbers to nearest 10 or 100 or 1000.

Stage 3- Students do not need to refer to number line or poem or rule, they just know how to round to nearest 1000.

Stage 4- Students can round 4 digit numbers to the nearest hundred, 3 digit numbers to the nearest ten, etc. They can do this because they have a solid understanding of place value.

Stage 5- I’m actually not sure where to go from here!!
