Fill in the blank. The length of the crayon is about what centimeters? Hint, use the halfway mark on the ruler to measure to the nearest centimeter.

The question is asking us to estimate the length of the crayon. And it tells us to do this by rounding the length to the nearest centimeter. And the hint tells us to use the halfway mark on the ruler to help us measure to the nearest centimeter. The two pink arrows on the ruler show us the length of the crayon.

We can see that the crayon is between six and seven centimeters long. The hint tells us to use the half way mark on the ruler to help us measure to the nearest centimeter. Halfway between six and seven centimeters is six and a half centimeters, or 6.5 centimeters. This is because if the crayon measures more than 6.5 centimeters, we can round it up to seven centimeters.

And if the crayon measures less than the halfway mark, we would round it down to six centimeters. This is the length of the crayon. It’s two divisions past the halfway mark, or two-tenths past the halfway mark. So, the nearest centimeter is seven centimeters. The crayon measures more than six and a half centimeters, so the length of the crayon is about seven centimeters. We used the halfway mark on the ruler to measure to the nearest centimeter.
