The accuracy of a measurement is how close the measurement is to the true value. If you were to hit four different golf balls toward an over-sized hole, all of them might land in the hole. These shots would all be accurate because they all landed in the hole. This is illustrated in the sketch below.
As you can see from the sketch above, the four golf balls did not land as close to one another as they could have. Each one landed in a different part of the hole. Therefore, these shots are not very precise. The precision of measurements is how close they are to each other. If you make the same measurement twice, the answers are precise if they are the same or at least very close to one another. The golf balls in the sketch below landed quite close together in a cluster, so they would be considered precise. However, they are all far from the hole, so they are not accurate.
Review the concepts of accuracy and precision. Then play the dart game until you obtain scores that are both accurate and precise.

For the length animation chose measuring "tenths" under the centimeters heading.
First day homework assignment. This is not so much about measuring as following instructions and thinking outside the box. However, careful measuring is important for this assignment so you will make a proper square at the end.
