Multiplication & Division Playground
See multiplication as building an array (rows × columns), see division as sharing a set of items fairly into equal groups, and understand a remainder as the leftover that could not be shared evenly.
Before you try
What if you shared 13 candies fairly between 4 friends? Would everyone get the same amount?

What happened?
Move a control to see what changes and why.
Groups and arrays are always whole objects. Division in real life often leaves parts rather than neat remainders.

Try these ideas
- Build a 6 rows × 6 columns array. Is 36 a square number? Why does that show up as a square shape?
- Switch to Share mode with 20 items and 5 friends. Is there a remainder?
- In Share mode, find two different combinations of items and friends that both leave a remainder of 2.
Why it works
Multiplying two numbers is the same as arranging that many counters into a rectangle: the first number is how many rows, the second is how many columns, and the total is every counter in the array. Build any array from 1×1 up to 10×10 and watch the total change.
Dividing is the opposite: sharing a set of items fairly into equal groups. Switch to Share mode, choose how many friends you are sharing with and how many items there are, and see how many each friend gets. When the sharing is not exact, the leftover items are called the remainder, and they are drawn separately, never handed out unevenly.
Check your understanding
Question 1 of 4
An array has 4 rows and 3 columns. How many counters are there in total?
You share 13 candies equally among 4 friends. How many does each friend get, and how many are left over?
Which of these equals 5 × 6?
You try to share 7 candies equally among 3 friends. Can everyone get the same amount with none left over?

For parents & teachers
- Ask your child to guess the total before counting the array. Were they close?
- Share real snacks among family members and check the remainder together.
- Ask: is 3 × 4 the same as 4 × 3? Build both arrays in Multiply mode and compare.
