In a code, CAT is written as DBU. Using the same code, how is DOG written?

Correct: A — EPH. Each letter moves one place forward: D→E, O→P, G→H, giving EPH.

If MOUSE is coded as NPVTF, which word is coded as IPSTF?

Correct: A — HORSE. The rule is +1, so decode by going back one: I→H, P→O, S→R, T→S, F→E — HORSE.

If SLOW is coded as WOLS, how is FAST coded?

Correct: A — TSAF. The letters are reversed: F-A-S-T backwards is T-S-A-F.

In a code A = 1, B = 2, C = 3 and so on. What is the code for CAB?

Correct: B — 3-1-2. C = 3, A = 1, B = 2, so CAB is written 3-1-2.

Tip for parents: let your child attempt every question before you step in. The explanation appears straight after they answer — read it together, then use Start again a day or two later to check it has stuck.
