Multiplication with Objects
What is Multiplication with Objects?
One of the easiest ways for kids to picture multiplication is by turning it into a rectangle. Say you want to multiply 5 by 7 — just draw 5 rows with 7 little squares in each, then count them all. Suddenly, multiplication isn’t abstract at all, it’s just a picture of how things are arranged.
There are other ways too. Imagine 5 bags, and in each bag you put 7 pinecones. Counting them bag by bag gives the same result:
1 bag → 7 pinecones
2 bags → 14 pinecones
3 bags → 21 pinecones
4 bags → 28 pinecones
5 bags → 35 pinecones
So we see that 35 = 7 + 7 + 7 + 7 + 7 = 5 × 7.
The number patterns that appear when you keep adding groups of 7 are interesting in their own right. Check out our article on skip counting to explore this idea further.
Why Does It Matter for Kids?
In traditional schooling, memorizing the multiplication table and calculating quickly were once top priorities. In Hans Christian Andersen’s The Snow Queen, there’s this scene where Kay tries to say the Lord’s Prayer but all he can think about is the multiplication table. That story shows how much weight people once put on memorizing math facts. These days, the focus has shifted. Instead of racing through facts, we want kids to understand what multiplication actually means and how it ties into daily life.
Research shows that using manipulatives when learning multiplication is crucial. Children who worked with blocks, counters, or tokens — compared to those who only received oral explanations and written drills — developed a much stronger grasp of multiplication and division. Even after moving beyond physical objects, these kids could carry their understanding into mental and written math.
Of course, objects alone don’t create understanding. Teachers help kids bridge that gap between hands-on actions and the math behind it. The move from concrete to abstract doesn’t happen all at once — it goes step by step from working with clearly structured objects (like 3 rows of 7 apples) through interaction with pictures and diagrams (like dot grids or a number line) to abstract reasoning (like 3 rows of 7 plus 4 rows of 7 equals 7 groups of 7). Objects should be simple and schematic — realistic toys like fancy cars can distract, while plain counters or squares keep the focus on math.
Multiplication, when kids see it as a neat way of counting, often shown with rectangular arrays, suddenly makes sense. They notice that adding 4 + 4 + 4 + 4 + 4 again and again can be written in a shorter way: 4 × 5. It looks almost obvious once they’ve seen it drawn. Research shows that this kind of early, concrete practice lays a strong foundation and makes the later move into abstract math much smoother. Their skills transfer to word problems, division, and even proportions.
Working with objects also builds a solid foundation for multiplicative thinking — the ability to reason with multiplication and division. Consider a simple example: if 4 oranges cost 13, then 8 oranges cost 26. Children who think in terms of multiplication see this immediately, without first breaking it down into the price of one orange. Multiplicative thinking helps kids manage money problems, notice patterns in the times table, and apply their knowledge to shapes, area, perimeter, or proportion questions involving fractions and percentages without relying on rote memory.
How Do We Teach?
When kids first think of multiplication as repeated addition, the commutative property can feel surprising. How can you show that 3 + 3 + 3 + 3 + 3 + 3 + 3 = 7 + 7 + 7?
It looks strange at first, doesn’t it? But if you draw 7 rows with 3 squares in each, the picture becomes clear: both sides represent the same rectangle. You can count the squares row by row to get a sum of sevens 3s, or column by column to get a sum of three 7s.
In our base-10 system, the numbers 2 and 5 play a special role. Counting by 5s lands on every multiple of 10 without skipping: 5, 10, 15, 20, 25, 30… The same happens when counting by 2s: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20… and so on. The final digit follows a repeating pattern in every decade. That’s why we give extra attention to multiplying by 2 and by 5.
Step by step, kids also learn to skip-count by 3s, 4s, and beyond. This helps them see how the multiplication table is organized. For example, they notice where the numbers ending in 0 appear, and how numbers in the same row connect to each other. With this understanding, they can find products without memorizing them. If they know that 8 × 10 = 80, it’s easy to figure out 8 × 9 — it’s just one eight less.
First Steps
Even Numbers and Skip Counting
Kids can be introduced to multiplication as repeated addition quite early. They usually pick up skip counting by 2s quickly — just count without saying the odd numbers: 2, 4, 6, 8, 10, and so on.
Even numbers can serve as anchor points on the number line — every odd number is just 1 away from an even.
If your unit of measure has a length of 2, you’ll need to count by 2s again to find the length of what you’re measuring.
Through practice, kids discover that adding even numbers always gives an even result, while adding odd numbers can produce either an even or an odd.
And of course, objects don’t have to be grouped in pairs — you can group them in 3s, 5s, or any equal-sized sets.

Structures and Patterns
In our base-10 system, the number 5 plays a special role — it’s halfway to 10.That’s why on rulers and measuring tapes you’ll so often see the little marks at every 5. Kids quickly get used to leaning on those “halfway points” when they work on the number line, and it really helps them keep track of where they are.
Counting by 5s is also powerful. It makes it easy to handle larger quantities when they’re organized into groups of 5. Two 5s make a 10, and then you just add whatever is left.

Counting gets easier when things are in neat groups. For example, kids can count by 4s: 4, 8, 12, 16, and so on.
Pictures make this even clearer. Imagine a kid working out the cost of an ice cream: the cone is 10, two strawberry scoops at 5 each makes 20, then two blueberry scoops at 5 each takes it to 28. On paper that’s four steps. But when they see the picture, most kids just do it in their heads without even noticing they’re calculating.
Step by step, kids start handling trickier shopping problems. For example, they might notice that if one pink candy costs 8 more than a green one, then two pink candies must be 16 more than two green ones. These little discoveries help them make sense of the multiplication table — it’s not just numbers on a chart anymore, but something they can reason about.

Multiplication Table
Kids get used to writing multiplication facts and representing them as rectangles.
This way of looking at multiplication is especially important. On one hand, it makes the commutative property clear. On the other, it shows that any number in the multiplication table can be found by drawing a rectangle to the left and upward from that cell — then counting the squares inside.

Equal areas
We explore many different kinds of tables with kids, so by the time they meet the multiplication table, its structure already feels familiar. The table itself invites lots of questions to investigate: How many times does the number 36 appear? Where are the even numbers? Which numbers end with 0?
Square numbers — products of a number by itself — play a special role. Kids tend to remember them more quickly than other products. They also learn how to move from one fact in the table to a neighboring one. For example, knowing that 8 × 8 is 64 makes it easy to find 8 × 9 — just add one more 8.
With the help of visual models, kids begin to record surprisingly complex expressions that combine multiplication and addition.

Big Ideas
Two key ideas for all of mathematics are hidden inside the very definition of multiplication.
If we define multiplication as the number of squares in a rectangle, we arrive at the concept of area. Later on, kids will calculate the areas of more complex shapes, like triangles or circular sectors. For even more complicated figures, mathematicians use integrals.
If we think of multiplication as repeated addition, we can extend that to repeated multiplication — and reach the idea of powers. For example, every power of 10 is written as a 1 followed by a string of zeros. These numbers are fundamental: any number can be expressed as a sum of powers of 10 with small coefficients (from 0 to 9).
In programming, powers of 2 are just as important. Information is measured in bytes, with each byte equal to 8 bits. A kilobyte is 1024 bytes, and so on.
