Montessori number activities – Number names

How should we introduce basic mathematical concepts in an Early Years setting? Let Barbara Isaacs count the ways with these Montessori number activities and ideas…

Many children know number names when they first come to nursery; they hear them in everyday conversations and in nursery rhymes and stories. They also recognise numerals – particularly ones that are relevant to their lives, such as those of their birthday or on washing machines, televisions and cars.

Some can also count in sequence from 1 to 10, and even to 20. This is especially true if they have older friends or siblings. Helping young children make connections between numerical names and symbols is often the task of early years practitioners, who need to establish the link between quantity and these signifiers.

Montessori number activities

In Montessori classrooms we have specifically designed materials that introduce children to the concept of one-to-one correspondence between name, quantity and numeral.

We scaffold the children’s learning by progressing in small steps – starting with counting using wooden rods, spindles, counters and glass beads.

The wooden rods are connected. A red or blue stripe represents each quantity to make the counting easier. When using spindles or counters we make sure that the child has the correct number, corresponding to the set of numerals. We also check that the spindles, counters or beads used are of the same colour.

Both of these pedagogical devices are intentional, so as not to distract children from the task of counting.

The next step is to explore numerals. Do this initially via sandpaper numbers. As the name suggests, these feature textured symbols to ensure a multisensory experience that combines the shape and name (sound) of the number.

This approach lies at the heart of all learning in the Montessori classroom. We eventually replace this with the printed numerals 0–10, then 10–99. Later, the green, blue, red and green printed numerals represent the decimal hierarchies from units to thousands.

The process is always the same. After introducing children to quantity and symbols, they have the opportunity to combine the two together.

Numbers for life

Supplement and enhance these relatively formal Montessori number activities and embed them into nursery life through daily use. For example, you might count how many boys and girls are attending on any one day or sing number songs.

Make sure there are also counting books on the shelf. These can include not only familiar titles such as Counting with Spot but also more unusual offerings like I Spy – Numbers in Art (HarperCollins Children’s Books).

Regular cooking activities and setting the table for snack or lunch time further enhances the daily use of numbers. It also promotes accuracy in counting and number recognition.

These tasks also use mathematical language such as more, less and plenty, as well as words like add and take away. These highlight for children the relevance of numbers in everyday life.

Introduce mathematical concepts such as pairing, sorting and grading in the sensorial areas of your Montessori classroom. They provide the foundation for mathematical thinking. This is not only in relation to counting but also in preparation for study of shapes, patterns and relationships.

There are counting opportunities in the outdoor classroom, too. Children can number the steps of the slide and identify numerals painted on the ride-ons as they return them to their place in a designated ‘parking bay’.

They can also practise one-to-one correspondence when planting out seedlings. Or count out conkers, acorns, shells or pebbles into baskets or pots organised into a number line.

Traditional playground games such as ‘What’s the time Mr Wolf’ and ‘Farmer in the Den’ are engaging ways for children to enhance their counting skills and understanding of mathematical concepts. In fact, if you look you will find joyful number opportunities in every corner of the classroom – so have fun!
