Matrix Math

Visualisation Challenge

How many cubes can be added to this solid without changing the front view or side view?

This is a common trap in cube visualisation questions.
Students often count only what they can see, but the key is to ask:

“What is the maximum height allowed at each hidden position?”

Answer: 4 cubes

At Matrix Math, we train students to approach visualisation questions systematically, not by guessing from the 3D picture.

Did you know the Great Pyramid has some amazing math behind it?

Its base is almost a perfect square, with all four sides nearly the same length.

And here’s the surprising part — if you divide its base perimeter by twice its height, the answer is very close to π.

A beautiful example of geometry in real life.

Yenni gives John $2.

Now they have the same amount.

So… how much more money did Yenni have than John at first?

Careful — the answer is not $2.

Think about what happens when money is transferred from one person to another.

Four bags. Three clues. One heaviest bag.

Can your child work it out using logic — not guessing?
