      How to Play

      Tap a square or a clue, then type your answer. The cursor moves on by itself. Tap the same square again to switch between Across and Down. “Check answers” shows right letters in green and wrong letters in red. “Reveal letter” fills in one letter for the selected word.

      Why Solve Crosswords?

      A crossword makes you think about meaning and spelling together. The crossing letters give you hints, so each correct answer helps you find the next one.

      Practise with pen and paper as well. Writing out your working helps you remember each method.

      Maths Words: A Quick Guide

      A maths crossword trains you to match a meaning to the correct word. Knowing the exact word helps in exams, because questions and mark schemes use these terms. Clues give a definition, and the number in brackets tells you how many letters the answer has.

      Three worked examples

      Example 1 · Use the length

      Clue: "To take one number away from another (8)". The answer must have 8 letters. SUBTRACT has 8 letters: S-U-B-T-R-A-C-T.

      Example 2 · Use crossing letters

      In the Basic puzzle, ADD (across) crosses SQUARE (down) at the letter A. Once you know ADD, you already have the 4th letter of SQUARE.

      Example 3 · Perimeter or area?

      A rectangle is 5 cm by 3 cm. The perimeter is the distance around the edge: 2 × (5 + 3) = 16 cm. The area is the surface inside: 5 × 3 = 15 cm².

      Three common mistakes

      Ignoring the number of letters. A word that fits the meaning but not the length is wrong. Count the boxes first.
      Mixing up similar words. A factor of 12 divides into 12 (3 is a factor). A multiple of 3 is made by multiplying 3 (12 is a multiple). Perimeter and area are also easy to swap.
      Guessing without checking crossing letters. If a crossing word gives you a different letter, one of the two words is wrong. Fix it before you go on.

      How to use the crossword

      1. Choose Basic, Intermediate or Advanced. Start with Basic if you are unsure.
      2. Tap a clue or a square and type the answer. Tap the same square again to switch between Across and Down.
      3. Press Check answers: green letters are right and red letters are wrong. Reveal letter helps when you are stuck.
      4. Press Start again to clear the grid and try to beat your time.
