Answer 1

1 Ask any contractor or construction worker--they'll tell you just how important math is when it comes to building anything. To create something of lasting value out of raw materials requires creativity, the right set of tools, and a broad range of mathematics.

Figuring the total amount of concrete needed for a slab; accurately measuring lengths, widths, and angles; and estimating project costs are just a few of the many cases in which math is necessary for real-life home improvement projects

2 One of the more obvious places to find people using math in everyday life is at your neighborhood grocery store. Grocery shopping requires a broad range of math knowledge from multiplication to estimation and percentages.

Each time you calculate the price per unit, weigh produce, figure percentage discounts, and estimate the final price, you're using math in your shopping experience.

3 After all, recipes are really just mathematical algorithms or self-contained, step-by-step sets of operations to be performed. The proof is in the pudding!

Working in the kitchen requires a wide range of mathematical knowledge, including but not limited to:

measuring ingredients to follow a recipe

multiplying / dividing fractions to account for more or less than a single batch

converting a recipe from Celsius to Fahrenheit

converting a recipe from metric (mL) to US standard units (teaspoon, tablespoon, cups)

calculating cooking time per each item and adjusting accordingly

calculating pounds per hour of required cooking time

understanding ratios and proportions, particularly in baking (ex. the recipe calls for 1 egg and 2 cups of flour, then the ratio of eggs to flour is 1:2).

Following a recipe can sometimes be tricky, especially if conversions are necessary. We Americans follow our own set of rules when it comes to most forms of measurement. Conversions make it a bit more difficult to follow recipes from other countries as they most likely use Celsius and the metric system.

4 Math comes in handy when traveling.

Think of it: when you travel, math comes along for the ride--from estimating the amount of fuel you’ll need to planning out a trip based on miles per hour and distance traveled. Calculating fuel usage is crucial to long distance travel. Without it, you may find yourself stranded without gas or on the road for much longer than anticipated. You may also use math throughout the trip by paying for tolls, counting exit numbers, checking tire pressure, etc.

5 you can show students how to use their math skills for reading maps. Why? It will make them safer travelers and less dependent on technology.

In order to use any map, you must first orient yourself (e.g., you have to find your current position on the map). This will be point A. The simplest way to orient yourself is to locate the town you’re in. Next, pinpoint nearby crossroads, intersections, or an easily identifiable point such as a bridge, building, or highway entrance. Once you’ve established a starting point, locate where on you want to go (point B). Now you can determine the best route depending on terrain, speed limit, and so on.
