Target 10 – Like a Word Search but with Numbers

title

It is great fun when you have precocious grandchildren who have creative and inventive minds.  One of my grandkids is really into word search puzzles.  He loves finding the names of states, or capitals, or astronomy words, or anything else that might be the theme of a word search puzzle.  But the gears in that creative mind started spinning one day and he created a search type of puzzle with numbers.  The gist of the idea was to write an array of random numbers on graph paper and then pick a random target number and try to find numbers in the array that add up to the target number.  This concept gave birth to an iOS and tvOS app named Target 10.

The screen above shows the main game board for Target 10.  The object of Target 10 is to earn 10 stars by finding sets of numbers in the grid that add up to the target number.

Target 10 offers four levels. On an iPad simply tap the Settings icon and then from a screen similar to the one show below, choose a level.  If you are using Apple TV you swipe to get to the Settings Icon and then swipe and click to choose a level.

Automatically a new puzzle is generated at the level you selected.  Study the puzzle to find chains of numbers that add up to the target number.  There’s a fun little twist.  The position of any two numbers can be switched.  When you can’t find any more sets of numbers to make the target sum, try using the Switch icon to move numbers.  To do a switch tap the Switch icon and then navigate to the two numbers whose positions you want to switch. If you are still stuck, you can tap the New Board icon for a new grid.

Continue finding sets of numbers that add up to the target number until you have earned 10 stars.

In designing this app I wanted to motivate elementary age students to get quicker at mental math.  It is my intention that by using Target 10 on your iOS device or Apple TV you will be able to engage students problem solving and strategic thinking activities that they will enjoy. The tvOS version of Target 10 offers the same great features as the iOS version, and additionally can be controlled using tvOS compatible game controllers so maybe the kids will think they are playing a video game.

Target 10 is available with a volume discount for educational institutions.  Target 10 is available worldwide exclusively through the Apple’s App Store.  It also available through Apple’s volume purchase program. Schools get a significant discount when purchasing multiple copies of Target 10. Contact Apple Education for more information about the volume purchase program.  Please visit Ventura Educational Systems’ website for more information about this and other iOS and tvOS apps for education.

Math Widgets IV Financial Literacy

title

Finding out just how much things cost is a right of passage that all teenagers must go through as they transition into adulthood.  Math Widgets IV help students understand personal finances by presenting four typical scenarios that involve savings accounts, automobile purchases, home purchases and using credit cards.

screen_2Cartoon characters pop up while using the app in order to set up a scenario involving personal financial decisions.

character_2

Rather than performing difficult calculations, the app is more about deciding which numbers should be used in the formulas.  Help screens give some background information for the various calculations.

screen_5

Numbers are entered into fields. Calculations for missing values are performed by moving the target to the desired field.

screen_4

Tapping the ‘info’ button reveals the formula used for the target calculation.

Fraction Builder

I submitted Fraction Builder to iTunes yesterday and it was approved in less than an hour!  It is so amazing to me what great service Apple offers to developers.  I certainly appreciate the way that the App Store provides access to my work to students and teachers all over the world.

title

In most of my math apps I try to make them icon-based so that language skills are not critical for working with concepts.  Fraction Builder has a series of icons across the top of the screen.  Tapping each icon results in a specific function.

For example, tapping the red dice generates a random fraction.  Denominators range from 1 to 12.  Once the denominator is set, numerators can be any number that results in a proper fraction.

icon_dice

When the question mark is tapped, a question is generated and displayed on a moveable note.  To answer the question students drag number tiles to make the fraction.  Usually it is best to start with the denominator.  If using this app in a classroom, the teacher should explain that the denominator represents the number of equal parts.  For this example, the student would first slide the three tile to the denominator position.  Next, the student should slide a one to the numerator position.  Once the numerator and denominator have been properly set, the students should tap the check mark.  When this icon is tapped the app compares the students answer to the correct answer for the question.

screen_2

A scoreboard displays student progress as they work with the app.  It shows the topic, number of questions attempted and the percent correct.  Quiz questions are based on three main topic areas:

• Naming Fractions

• Equivalent Fractions

• Comparing Fractions

Various other functions are performed when other icons are tapped.  This chart explains the other functions.notebook

I hope that teachers will let me know if they are interested in evaluating this app for use at their school.   I have a limited number of download codes for FREE evaluation copies of this app.   For some students learning about fractions is difficult.  It is my hope that this colorful interactive app will help them in their journey to master fraction concepts.

 

Save the Galaxy!

I guess I am on a monsters kick lately.  My latest strategy game involves monsters that have invaded the galaxy.  Your job is to use logical thinking skills to save the galaxy!

title

To solve the puzzle the player must swipe in the direction that they wish the monster to move.  The app is available for both iOS and Apple TV.  On an iPad the player swipes the screen to specify the direction.  If you are playing on an Apple TV either the Siri remote or a bluetooth compatible game controller can be used.

screen_4

The galaxy is divided into 20 sectors so there are 20 puzzles in the app.  The app has a 3-D look to it and animation adds to the effect that you are traveling through space.  As you might of guessed I am a StarTrek fan doing an app with a space theme was fun for me.

I hope you enjoy playing Space Monsters! Save the Galaxy. A limited number of free promotional codes are available by request.  The app is offered exclusively by the iTunes App Store and sells for $0.99.  Please visit our website for more information about this and other apps for education.

Line Design (a.k.a. String Art)

In general, one of my goals in designing the Hands-On Math apps was to create ways to simulate learning experiences that students would have if using actual manipulatives.  Simulated manipulatives can offer additional learning opportunities.

line_design.png

Special features, in the Line Design app, take the learning opportunities beyond what can be down with physical manipulates.  For example, a grid with the x and y axes labelled can be added to the image.

line_design_2

Line Design can be used for exploring the relationship between geometry and art.  In addition to calling line designs, string art, sometimes it is referred to as aesthenometry, Using the term, aesthenometry, refers more to the aesthetic beauty of the designs.

line_design_3.png

It is always fun for students to use boards, nails and various colors of embroidery thread to make string artworks to hang on their wall.  The process involves lots of careful planning, measuring and some materials (boards, nails and string).  The Line Design app can be used to plan the project and to provide help in choosing the colors and design patterns to be used.

Personally my favorite pattern to use for instructional purposes is the circle.  When the circle design is selected a slider appears.  Using the slider the number of points on the circle can be set to any number between 3 and 36.

line_design_4

There are lots of mathematically interesting explorations that are available in this mode.  Here are a couple of suggestions:

  1. With the number of points set to 12, what shape will result if lines are draw to connect every other point?
  2. What shape results when the number of points is set to 10 and every other point is connected.  What about connecting every fourth point.
  3. What’s the difference between setting the number of points to a prime number versus a composite number?
  4. Set the number of points to 24.  Explore connecting every 4, 6, or 8 point.

The learning environment gets even richer if the circular protractor is added to the iPad display.  In this mode students can measure angles. Here we have the number of points set to 36.  The screen shows a 30° angle.  Two legs of the triangle are radii of the same circle and therefore congruent.  What is the measure of the other two angles?

Election 2016

With the presidential election coming up in November of this year, I thought it would be beneficial for teachers to have an app that helps to explain the election process and the meaning of the Electoral College.  The world’s attention is focused on the U.S. Election since the outcome will have a profound effect all countries.  It is important for U.S. citizens to understand how the process works.

title

The app has historical data from 1976 to present and by tapping icons the user can manipulate the U.S. map to show which states cast their votes for the Democratic candidates and which voted Republican in previous elections.  It’s interesting to tap through the years and watch the map change dynamically.  At any point the user can tap the issues icon to display  a short list of the major issues of the day.

If desired, as the user taps through the presidential election years the symbol for the winning party can be displayed.

symbol_democraticsymbol_republican

One of the best features of the app is the Electoral Vote scorecard for the 2016 election.  Here the user can predict which states they think will be red Republican States and which will be blue Democratic states.  User can test different scenarios to see how their favorite candidate might win.  Will 2016 be a landslide or a narrow victory.  Only time will tell…

Get your students involved in the political process and help them better understand the Electoral College using Election 2016.
