But there are still "real world" things to think about, such as "will it be strong enough? But wait a minute It has been decided the box should hold 0. Well, the formula only makes sense for widths greater than zero, and I also found that for widths above 0. In fact, looking at the graph, the width could be anywhere between 0. By comparing this to the weather on each day they can make a mathematical model of sales versus weather.
They can then predict future sales based on the weather forecast, and decide how many ice creams they need to make Mathematical models can get very complex, and so the mathematical rules are often written into computer programs, to make a computer model.

We know three measurements: The cardboard is "t" thick, and all measurements are outside the box The inside measurements need to be reduced by the thickness of each side: The inside length is l-2t The inside width is w-2t , The inside height is h-2t and now the formula is: Your company uses xx mm size boxes, and the cardboard is 5mm thick.
Someone suggests using 4mm cardboard Let us compare the two volumes: How do we write this as an equation?
As a student learns and gets neater, then using graph paper is no longer needed. One good way is to have things that can be moved and manipulated to work out concepts. For subtraction, you can have objects arranged or available and have students take items away from the group. Then have students relate about how many items or objects are left. Model for your children to examine and read word problems more than one time.
Math has a specific method of expression, and to solve and learn how to solve math problems, you have to follow the methods.
Some children will benefit from drawing a diagram or a picture to show what has happened in the word problem. Consider an alternative to a specific word problem, such as replacing large numbers with small numbers. Once a child can understand HOW to solve a word problem, and then often they can solve other similar problems with ease.
Math is a topic or subject where each step or process is always based on the concepts learned just previous. For example if you are having a problem with simple addition, it will be difficult to teach simple subtraction. One way is to make sure there is a backup help source.
An alternative is to have a teacher resource in another room at the same grade, or with a parent, tutor or other adult that can help the student if they get stuck. If your school has a homework hotline or resource center then these can be a source of assistance also. A way to solve math problems is by doing it mentally, or "in ones head".
Children who learn this method in a basic way are more likely to be able to apply this with more complex problems. One method is when you assist children in a math problem, look for opportunities to prompt them to do it mentally without writing it down.
Teach the basics, but encourage them to master these concepts by working to do the basics swiftly. If a child can answer basic facts in less than five seconds three seconds is considered the benchmark then they have mastered that concept. Show them to start every problem by looking at similar problems, using the worksheet or examining the textbook.
Suggest that they take a sample problem and do it again, and pay attention to each step.
