You're trying to plan an activity for your third graders, who will be arriving around 2:30 in the afternoon. Today you want to do something associated with mathematics. Which one of the following activities would be appropriate?

A. Keeping track of the weather
B. Making a prism
C. Sorting objects according to weight
D. Studying the composition of rocks.

I chose C, can someone tell me if I am correct.

For math, yes.

Thanks for your help.

You're welcome!

To determine if sorting objects according to weight is an appropriate mathematical activity for third graders, let's analyze each option:

A. Keeping track of the weather: While observing the weather can involve some measurement and data collection, it is not directly related to mathematical concepts such as sorting or measurement.

B. Making a prism: This activity could involve identifying and classifying different shapes and their properties, which aligns with mathematical concepts. However, without additional information on how the activity connects to specific mathematical skills, it is difficult to determine its appropriateness.

C. Sorting objects according to weight: Sorting objects based on weight can be a great activity for developing measurement and comparison skills, which are important mathematical concepts. It involves observing, comparing, and ordering objects according to a specific attribute (weight). Considering these factors, this activity seems like an appropriate choice.

D. Studying the composition of rocks: While studying rocks can be an interesting and educational activity, it is not directly associated with mathematics. This topic falls more within the realm of geology or earth science than mathematics.

Based on the analysis, it appears that your choice of C, sorting objects according to weight, is indeed an appropriate mathematical activity for third graders.
