Concept 1 of 6

Alphabet Position: A=1, B=2, ..., Z=26

1

Today's big idea

Jump to the nearest anchor (E=5, J=10, O=15, T=20), then count the last few steps.

Landmark letters like E, J, O and T save counting from A every time.

How it works

👀 What's going on?

When your class lines up, you know who is first, who is fourth and who is last. The alphabet lines up in exactly the same way. A stands first, B stands second, and Z stands right at the back in place 26.

💡 Here's the trick

Every letter has a position numberA1B2C3D4E5F6G7H8I9J10K11L12M13N14O15P16Q17R18S19T20U21V22W23X24Y25Z26Anchors: E=5 · J=10 · O=15 · T=20Count forward or back from the nearest anchor

Look at the strip above. Four squares are shaded gold: E, J, O and T. Those four are your anchors, worth 5, 10, 15 and 20. Once you know them you never count all the way from A again.

🪄 How to do it

  1. 1.Find the nearest gold anchor to your letter on the strip above.
  2. 2.Write down that anchor's number: E is 5, J is 10, O is 15, T is 20.
  3. 3.Step forward or backward from the anchor to your letter.
  4. 4.The number you land on is your letter's position.

✍️ Try it

Which letter sits at position 12? Now a harder one: the positions of F and one more letter add up to 20. Which letter is it?

Position 12 is L, because J is 10, then K is 11 and L is 12. For the second, F is 6 and 20 minus 6 is 14, and the 14th letter is N.

⚠️ Watch out

You might be thinking you can just count up from A every single time. That is fine for B or C. For W you would count 23 steps, and one slip ruins every count after it. From the anchor T you only step three places.

🌟 Why this matters

Alphabet positions are the reason a register, a contact list and a library shelf all sort themselves the same way. Knowing O is 15 tells you an O name sits past the middle, so you open the folder near the back.
Exam tip: Class 3 reasoning questions ask for a letter's position directly, so these four anchors save real time.

Watch me solve one

Quanta solves it

“Watch how I think through one of these — then you try.”

THE PROBLEM

“What is the 7th letter of the English alphabet?”

  1. 1

    Pick the nearest anchor

    Anchor: E = 5.

  2. 2

    Count forward to 7

    E (5) → F (6) → G (7).

  3. 3

    Confirm

    5 + 2 = 7 → G

  4. 4

    Answer ✓

    7th letter = G
