Teachers may want to consider introducing Montessori Numbers to a small group or in a full-class lesson before setting kids to work solo.
The activities require a bit of self-motivation as they present basic tasks, but no goals. Kids who are not familiar with the rods and blocks may need further guidance before they understand the system. Teachers may also want to supplement with concrete items to represent the individual objects students are working with onscreen; anything from small crackers to buttons will do. For solo student play, the Tracing and Building activities may be especially easy to catch on to, encouraging kids to play often for excellent practice on number writing and free play with numbers.Continue reading Show less
Montessori Numbers is a set of five math-related activities that follow the Montessori method. Maria Montessori's hands-on approach ("What the hand does, the mind remembers") is definitely incorporated. The app includes counting, block manipulation, stacking, number cards, and number matching. There's also a fun, engaging tracing activity for teaching kids the proper way to write numbers zero to nine while encouraging them to practice many times as they see the impressive, visually animated results of their work. Teachers can set the number range that kids can work with, as zero to nine, 10 to 99, or 100 to 999. Many Common Core standards are addressed directly or indirectly, including Counting & Cardinality, Operations and Algebraic Thinking, Number & Operations in Base Ten, and place value.
Montessori Numbers does an excellent job of taking one specific set of Montessori tools -- the blocks and number rods -- and incorporating them into an app. The rods can be changed from basic wooden blocks to cupcakes, cars, flowers, diamonds, and more, adding to the fun. Reinforcement of number names and counting occurs throughout visually and via voice recording; you may want to encourage students to count along. On the downside, there's no student user tracking. Also, this app may not appeal to every student, especially those who prefer working toward an end goal, such as completing a level or earning points or stickers.
Montessori Numbers provides many opportunities for young students to play with numbers in ways that bring abstract numeric ideas to concrete objects, even via an iPad screen. This is a real digital translation of a hands-on method, and classrooms that don't already have access to many sets of Montessori materials will benefit.
Key Standards Supported
Counting And Cardinality
Understand the relationship between numbers and quantities; connect counting to cardinality.
Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.
Count to 100 by ones and by tens.
Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
Number And Operations In Base Ten
Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
Count within 1000; skip-count by 5s, 10s, and 100s.
Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
Operations And Algebraic Thinking
Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
