Back to school

It is that time of year again, the kids are going back to school.

When you think that their math performance was not optimal or that they show any of the following early warning signs listed HERE take action to make sure you are ahead of any issues.

Our mission is to bring Awareness, Communication, Research and Remediation of Dyscalculia to those who may need it.

A first step is always to do our Dyscalculia Screener. Available FREE in the left navigation panel (free registration required).

If the outcome of that Screener indicates that there may be issues with math, please continue to explore this and consider doing the online Math and Dyscalculia Screening Test at    This will give you an app. five page report that provides a lot more specific insights.

When full testing is recommended, contact us for the available options.

Please ensure that the children have a great year in school and make sure they get the support they need when they have a learning issue.     

What is educational therapy? Do we need it for students with dyscalculia?

Educational therapy is personalized help so students can reach their full potential.

While regular tutoring focuses on helping students with home work and review for tests and quizzes, educational therapy has a different and complimentary focus and works on development and long term retention of basic math skills and can be started when regular math tutoring is not effective or not effective enough. Educational therapy is for students who seem to know it one day and forget it the next.

Educational therapy combines general study techniques and organizational skills for learning with specific attention for a subject, while also addressing psychological aspects like self confidence and persistence.

After getting a good feel for a student’s skills in a specific subject, the educational therapist selects tools and techniques to address the issues that stand in the way of reaching the student’s full potential. These techniques are demonstrated and practiced during educational therapy sessions so that the student learns to apply them in school or when doing homework or studying independently. 

Educational therapy is never ‘one size fits all’, and always personalized. For some students the emphasis lies on study techniques in general, that may carry over and help the student to become successful in several subjects. For some students the emphasis is predominantly on an area of weakness or LD such as dyslexia or dyscalculia. Although there is some overlap and students may have characteristics of both LD’s, it is now a clear that these LD’s need there own approach. Intervention for Math Learning Disability (MLD) and dyscalculia asks for a very different way of teaching new concepts and how to apply them, to develop fluency and check for understanding than intervention for reading and they are usually provided by different specialists.

Ideally, educational therapy should be tailored to fit the educational needs of a student like a glove, making it easier to handle the educational ‘hot potato’


My Favorite Apps for Dyscalculia

Tutoring children with Dyscalculia is most effective when done one on one. As it is valuable that the children continue to explore math between sessions, apps are a real good tool.

Apps come in all kind of forms and varieties. Many are free and some cost lots of money or give options to buy additional options from inside the app.

For an app to be effective for our purpose, I look for these things:

  • What does my student need to learn now?
  • Emphasize conceptual understanding
  • Balance entertainment and learning
  • How ‘busy’ is the screen?
  • How many adds?
  • How are mistakes handled? 
  • Reward for getting things right?
  • Do you see the results?

Below I show some of my favorite apps. I do not get paid to review these apps and I am also not involved in the development of these apps. Just a recommendation from my experience with these apps.

Math Concentration on the App Store on iTunes - Google Chrome 882015 25700 PM.bmp Math Concentration by NCTM, this is an electronic version of the classic Memory game, with multiple levels starting at matching dots with numerals to matching fractions and percent, for one or two players.

Self correcting: numbers don’t stick if you make a mistake. Grade 1 – 3
Make 10 Plus on the App Store on iTunes - Google Chrome 882015 23022 PM Make10Plus to learn the ’10 bonds’: similar to Find Sums, but with numbers instead of apples: all pairs that add up to ten by clicking on the other number that forms a pair with the presented number. Can be a bit fast in the beginning when child is starting to learn the ten bonds. Grade 1 – 2
 Number Rack, by The Math Learning Center on the App Store on iTunes - Google Chrome 882015 23743 PM.bmp Number Rack is the electronic version of the rekenrek (pronounced raikuhnreck), a manipulative from my native country the Netherlands. It has five red and five white beads, that slide on a metal bar in a very realistic fashion. You can add printed and written numbers to show the calculation; for larger numbers just add more bars. KG – Grade 2.
  Number Line from the Math Learning Center, shows the connection between the number and the place on the number line, the size of a number. It has multiple options such as changing the size of the number line, with and without numbers. Addition and subtraction are easy to visualize with forward and backward jumps, multiplication with multiple similar jumps and screen touch to combine multiple jumps. the How to has a clear explanation. App. is a generous donation from Dr David Moursund. Grade 1 – 5.
 Lobster Diver on the App Store on iTunes - Google Chrome 882015 25308 PM.bmp Lobster diver from New Mexico State University Learning Games Lab asks you to use an underwater number line to retrieve your lobsters, you need to be quick and watch out for the electric eel! Apart from learning the number line it also develops planning. Grade 1 – 3
  Visual Multiplication from Visual Math Learning starts with ‘Adding Beads’ a grid to drag balls with a number to their place. Two additional games are Chamber Maze, where you drag a ball with a nifty system to show  the number along a maze that shows the multiplication as an area, and Pool Table, a game where you multiply the numbers on two balls to go in the hole with the number of their multiplication
 Sushi Monster on the App Store on iTunes - Google Chrome 882015 25140 PM.bmp Sushi Monster from Scholastic has addition and multiplication by placing two plates with food and a  number on a round table in reach of a ravenous monster, who asks for a specific number and quickly gobbles up the food when the math is right.

Multiplication foldable arrays to learn multiplication facts greater than five

The fold-able array below has 10 x 10 = 100 dots.  Each of the four colored parts is 5 x 5 =25.

The product of two numbers is shown as groups of 5 plus some extra.  Use the five times multiplication table and add the extra’s. It will help children when you fold the numbers that are not used to the back.

Example 1:

What is 6 x 8? It is 6 rows of 8. Fold back between the 8 and 9 column, so you only see rows of 8. Fold between the 6 and 7 row, so you only see 6 rows.

Count the total: 5 blue groups of five, 3 green groups of five, 1 purple group of five:

5 + 3 + 1 = 9 groups of five. Nine groups of five = 45. Now add the extra red dots: 45 + 3 = 48.

zeskeerachtSome children see immediately that the blue section is 25 + 3 green fives and one purple 5 = 45 and start to count the extra 3 red dots:

                    45 + 3 = 48.

Some children like to color in or connect the groups of five dots with a line to make it easier to count the groups of five.


Example 2:

What is 9 x 7? It is 9 rows of 7. Fold back between the 7 and 8 column, so you only see rows of 7. Fold between the 9 and 10 row, so you see 9 rows.

Count the total: 5 blue groups of five, 2 green groups of five, 4 purple groups of five

5 + 2 + 4 = 11 groups of five.negenkeerzeven

Eleven groups of five = 55.

Now add the extra red dots:

55 + 8 = 63.


Note: this method links multiplication to area and lays the foundation to later grasp the distributive property and FOIL method to multiply polynomials: (5+4)(5+2) = 25+10+20+8
