01 Opening
Serif beat 1 of 5

Serif was a sharp-eyed mouse with a gift for spotting differences. Some letters looked so alike they tried to trick you — like b and d, or p and q. But Serif knew: look closely, and every letter shows you which one it really is.

02 Serif
Serif beat 2 of 5

Serif lined up a row of letters and found the matching pairs. "Here's an m... and here's another m — they're the SAME." She tapped them together. Matching same-shaped letters was like finding twins in a crowd.

03 Serif
Serif beat 3 of 5

Then came the tricky ones. A young mole mixed up b and d. "They look the same!" he groaned. "Look again," Serif said gently. "The b has its round belly on this side. The d has its round belly on the other side. Little difference, big clue." The mole looked — and saw it.

04 Serif
Serif beat 4 of 5

Serif made a game of the look-alikes. She'd hold up a letter, and the mole had to say if it was b or d, p or q. At first he was slow. But the more he looked for the little difference, the faster and surer he got.

05 Closing
Serif beat 5 of 5

By day's end, the mole could sort a whole pile — same letters together, tricky look-alikes told apart, b here and d there, no more mix-ups.

Serif twitched her whiskers, warm and proud. Telling almost-the-same letters apart took careful eyes. And now the mole had them — he could see the tiny difference that made each letter exactly itself.

  6. Vole: They look the same to me!
  7. Serif: Look close. On the b, the tummy is on the RIGHT. On the d, the tummy is on the LEFT. Same shapes — different directions.
  8. Narrator: The vole looked carefully at each one.
  9. Vole: This one's tummy faces right — so it's a b!

Reading together with a grown-up? A card for the grown-up

For the grown-up: ask one question, then wait. When they answer, add one word to what they said. Tap the button when they have said something — that is one turn each, a circle. Nothing is recorded or kept.

Let them finish it

Say “Serif: look closely — b and d look alike, …” and stop. Let them finish it.

Then say the whole line together: “Serif: look closely — b and d look alike, but they face different ways!”.

Now wait. Count slowly to five in your head. Their answer is worth the quiet.

Circles together: 0
