Matching Number and Quantity
The written numeral finally meets the quantity it stands for, counter by counter.
Matching Number and Quantity is a Montessori activity for a child aged 3 to 4 years. Area: Early Math. Time: 10-15 min.
What the activity builds
Connect the written symbol to the real quantity. Children often recite the number sequence and recognize the shape of a numeral, without the two ever meeting. Here, we build the bridge: this curved line means three things, exactly three.
The materials
- Five cards showing the numerals 1 through 5, written large and clear
- About twenty identical counters, in a small dish
- A mat or tray to define the work space
How to do it, step by step
- Line up the five numerals in order, left to right, without saying anything.
- Under the 1, place one counter. Under the 2, two counters, one below the other.
- Continue up to 3, then slide the dish toward your child and pull your hands back.
- They place the counters under the 4 and the 5, counting out loud if they need to.
- At the end, run a finger down each column together, without comment.
The parent's role
Pull your hands back after the third numeral: that's when the activity becomes theirs. If they place four counters under the 5, say nothing and don't fix it. Count along with them, finger by finger, starting from the first column: the column under 4 will be the same height as the one under 5, and it's that equality that will catch their eye, not your correction. Show once, then step back.
Safety
Counters large enough not to be swallowed, never coins or small buttons. An adult present as long as the child still puts objects in their mouth.
You remain the sole judge of what is right for your child. These activities are offered for educational and recreational purposes: they do not replace medical advice or the guidance of an early childhood professional.
Ways to adapt the activity
- Easier: stop at 3, with counters already sorted into three dishes.
- Harder: go up to 10, and shuffle the numerals before putting them back in order.
- Next step: drawing a numeral at random and going to find that many objects around the house.
