Introduction
In this activity, we will estimate the number the arrow points to on a number line to 100.
Example
Estimate the number the arrow is pointing to:
Answer
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 25, 26, 27, 28, 29, 30 would all be accepted.
Shall we try a few questions on this?
