Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
The five answers
What they say
The tallest sees nobody taller and says 0. The next says 1, then 2, then 3.
An answer that ignores the order
Shuffle them and nothing changes
Let the children rearrange and say their numbers again. The order of the answers changes.
What parity means
Two kinds of whole number
Every whole number is either even or odd: an even one splits into two equal halves and an odd one leaves one over.
And often exactly enough
A very small piece of information
Knowing a number is 24 tells you a lot. Knowing only that it is even tells you almost nothing.
Nothing is left over
Two evens
Take 6 and 8. Each splits into equal halves, so nothing is left over when they are put together.

A number that describes an arrangement, and grids
A number can answer a question about a group rather than measure anything, and the rule behind it is part of the information. Some answers survive rearranging, which makes them facts about the group. In a grid, work out…
- A number can answer a question about a group without measuring anything.
- Five children of unequal height answer 0, 1, 2, 3 and 4 in some order.
- Rearranging them changes the order of the answers, never the values.

Picking parity
Parity is which of the two kinds a whole number is. Two evens or two odds add to an even. One of each adds to an odd. A long total is odd exactly when an odd count of its numbers are odd.
- Parity is which of the two kinds a whole number is, even or odd.
- An even number splits into equal halves; an odd one leaves one over.
- Two evens add to an even, and two odds also add to an even.

The Virahanka numbers, and digits in disguise
A sequence can look back two steps: each term is the sum of the two before it. The Virahanka numbers come from counting verse rhythms, and a reason for the rule covers cases nobody counted. In a digit puzzle, rewriting b…
- Each term of the sequence is the sum of the two terms before it.
- The first ten terms are 1, 1, 2, 3, 5, 8, 13, 21, 34 and 55.
- They are named after Virahanka, who studied the rhythms of verse.
