Solving Math Word Problems in Numbers Using Algebra Part 2

High School Algebra, High School Mathematics

This is the fourth part of the Word Problem Solving on Number Problems and this is the continuation of the Solving Word Problems in Numbers in Algebra.  In this post, we discuss more examples on how to solve number problems. We start with the fourth example.

Example 4

The sum of three consecutive numbers is 78. What are the three numbers?

Solution

In the previous post in this series, we have already discussed how to solve problems about two consecutive odd integers. In this example, there are three consecutive integers, not odd and not even. As we can see, 11, 12, and 13 are consecutive integers and we only add 1 each time to get the next number. This means that if x is the smallest number, then x + 1 and x + 2 are the next two integers. » Read more

Video Games—Helping Students Develop Their Mathematical Skills

Games and Puzzles, High School Mathematics

Matthew C. Winner, a teacher and co-author of the book “Teach Math with the Wii,” shared that “in grade school we’re always trying to relate math to the real world. Some kids have been good at video games their whole lives and never realized they were doing math the whole time.” To meet the goals of K-12, schools are already adopting game-based teaching strategies to better engage students and teach Math effectively. With gaming tools like the Nintendo Wii and even smart devices, it’s now easier for them to relate mathematical concepts with real things.

Now, it’s really common to see students glued to handheld gaming devices or console controllers inside the classroom. If you check out the specs of the recently-released iPhone 5C on http://www.o2.co.uk, you’ll see that it was built for gaming. In fact, Bill Gates, billionaire-philanthropist and founder of Microsoft, revealed in an interview with The Atlanta Journal-Constitution that “imagine if kids poured their time and passion into a video game that taught them math concepts while they barely noticed, because it was so enjoyable.” Today’s technology is actually helping math-phobic students overcome their fear of math and improve their skills. » Read more

How to Print Screen on iPhones

Teaching Tools, Web 2.0 Technology

There are numerous and excellent iPhone apps that we can use in teaching mathematics as well as any subject that you can think of. Sometimes, we need to take a screenshots of these apps and show them to students through a projector or a large screen. Although iPhone is very popular, this feature is not.  In this post, we are going to learn how to perform print screen on iPhones. For newbies those who are not familiar with the term print screen, it only means that you are taking a picture of what is displayed on your screen.

Print Screen on Phones

How to Print Screen on iPhone

1.) Open the app or image that you want to capture.

2.) Hold the Home button of your iPhone.

3.) While holding the Home button, press the Sleep/Wake button. If you did it right, you will hear the camera shutter (only if the shutter sound of your phone is enabled).

4.) To open the screen capture, open your iPhone’s Camera Roll.

You can also use the steps above for taking screenshot on iPod Touch. Of course, it is also possible to do print screen on iPads.
