Select and use appropriate arithmetic operations in practical situations including developing a budget. Pretend you are going on a Mount Everest expedition. When planning a mountain climbing expedition, you did to think about many things. You need to think about equipment, food, clothing and other items that cost money.

Estimate, calculate and compare weight/mass and volume within customary and metric systems.

To complete this activity, you will need to pretend two things: 1) You will be actually climbing Mount Everest; and 2) You are an adult. You have to deal with many physical challenges when mountain climbing. One challenging task is to carry equipment and climb at the same time. You wear some of the equipment plus need to put some into backpacks. Either way, it adds more weight on top of your body weight. Let’s do a quick activity to figure out how much weight you will be "carrying" up the mountain in both metric and customary units.

Using a data set, compare mean, media and mode. Seven out of ten of the highest mountains in the world can be found in Nepal. All ten are in Asia. You can find dozens of mountain peaks in the Himalayas that are taller than Mt. McKinley. You might even say that Mt. McKinley would only be an average mountain in the Himalayas.

Use maps to analyze spatial patterns. Knowing how to read maps is essential in mountain climbing as well as in everyday life. Maps help guide you to where you want to go and help you better understand new places. Three types of maps are very important in any mountain climbing expedition. First, you need to know how to get to the mountain. Second, you need to be able to find the basecamp areas. Third, you need to be able to see the safest and best routes to take to the summit.
