Montessori Numbers is designed to help build sound mathematical foundations in children aged 3-7 by using a concrete, visually significant material inspired from the Montessori methodology.

Montessori Numbers offers a sequence of guided activities that gradually help children reinforce their skills. Each activity offers several levels of increasing complexity.

• Learn to count up to 999
• Experiment with quantities and learn their names
• Learn the numerals and their names
• Understand the relationship between numbers and quantities
• Understand the decimal system and place value
• Master the numerical order
• Learn to trace numbers

Montessori Numbers builds on the iPad’s touch feature, and uses verbal feedback for more efficient learning. The app can pronounce any number between 0 and 1009 (American, British and Australian voices available).


Common Core State Standard

This app will help your child in learning the following Common Core State Standards domains:
• Counting and Cardinality (K.CC)
• Operations and Algebraic Thinking (K.OA, 1.OA.1/2/5)
• Number & Operations in Base Ten (K.BNT,1.NBT.1/2/4/5/6, 2.NBT.1/2/3/5/8/9, 3.NBT.1/2). The app is great to deal with place value.



• Hundred Board
A great activity to help your child master the numerical order of 1-1000, and to introduce numerical patterns. The hundred board displays 100 numbers in a square. The first number (1,101,201,...) can be chosen so it can customized for each child

• 1 to 20
This activity is designed to introduce numbers.
3 levels of difficulty: 0 to 5, 0 to 10 and 11 to 20.

• Quantity
In this activity, kids associate quantities to numbers by manipulating units, bars of 10, and squares of 100 to match a given number which is pronounced and optionally displayed.
Levels of difficulty: 0 to 9, 10 to 99, 100 to 999 or custom

• Numerals
In this activity, number names are to be associated with numerals. As a number name is pronounced, kids are invited to build the corresponding numeral. Kids can freely experiment with numerals and hear the names associated with each numeral they build. The quantity representing the numbers built is also displayed to reinforce the association between quantity and numerals.
Levels of difficulty: 0 to 9, 10 to 99, 100 to 999 or custom

• Numerals (from Quantity)
In this activity, a quantity is to be associated with a given numeral. The child must build the number that matches the quantity displayed. This is the most complex activity because the child must count the quantity displayed, and then build the number using the numerals.
Levels of difficulty: 0 to 9, 10 to 99, 100 to 999 or custom

• Number Tracing
Learn to trace numbers with animations that follow the child's touch. Several options (size, difficulty, tracing style, show/hide model) are available to tailor the activity to your needs.

• Building Block Game:
A game can be started at the end of each activity (availability can be modified in settings). There is no “real” goal to this game - kids can play freely with the materials, thus becoming more familiar with them.

Misreading Numbers


This is a good substitute app for when a child is absent from school (Montessori) for long periods or for when reinforcement is needed. However, the numbers I. The hundreds are read incorrectly. The number "643", for example, is read as "six hundred and forty-three". The correct way to say the number is "six hundred forty-three." In math "and" represents the decimal point as in "six and one tenth" for the number "6.1". This is troublesome because is error is repeated with each number in every section. I sincerely hope this will be fixed.

Developer Response

Just choose the US voice in the settings to have the good pronunciation. The app offers several voices (US, British and Australian) because numbers pronunciation is not the same in these countries. You did select UK or Australian voice and that's why the app read numbers with "and".

Exceeded my expectations! I bought these for my 3 year old grandson, who is growing up in a trilingual culture. Amazing graphics. I have enjoyed playing with these games so much. Easily used, clear instructions, inviting play & learn. Better than promised! I bought preschool math, writing & letters individually...because I was sold on it after I tried the math version....JUST BUY THE BUNDLE!...the programs are well worth the price either way!

7 year old daughter focused well on this app


This morning I introduced Montessori Numbers to my seven year old daughter, entering 2nd grade. She started on the beginning levels and proceeded on her own intuitively throughout the app. At one point she turned to me and said, "Look Mom, I counted to 950!". I like the app because it's simple to follow, but has a flexible number of settings for activity, style and difficulty. Adding options for "flowers, diamonds and pearls" admittedly added engagement from a girls' point of view. Congratulations to this developer for consistent, educational, high quality releases. I hope to see more. --Mom of two girls, blogger, and app enthusiast.
