In this worksheet estimate the number the arrow points to on a number line to 100.
Estimate the number the arrow is pointing to.
Divide the line up into halves, quarters, etc and then take a guess at where you think the arrow is.
The half way point would be 50. The quarters would be at 25, 50, 75.
You could try tenths as well.
Here the answer is 28, but answers of 26, 27, 28, 29, 30 would be accepted.
