Exact letter conservation
Letter Inventory Detectives
Solve anagrams by keeping a letter inventory. A tempting word is only a solution when it fits the clue and uses every supplied letter exactly once. Players take turns proposing a word and checking its spelling against the inventory.
Work together, or form two small teams and rotate the writer. Age and time are planning estimates; choose the reading and arithmetic support that suit your group.

Print one player sheet per team and one host guide for the adult. Both are black and white. Keep the host guide separate to avoid revealing answers. No cutting, folding, special props or account required.
No printer? Copy the grids and prompts onto plain paper. The full activity is below; hints and answers stay closed until selected.
Set up and rules
Bring pencils, an eraser and one sheet of paper per team. Print at 100% / actual size. Read the rules together, try the warm-up, work through two rounds, and finish with the final challenge.
- Rearrange all the letters of each supplied word. Do not add, lose or replace a letter; repeated letters must keep their counts.
- Use the clue to choose the intended everyday English word. A different word may use the same letters but miss the clue.
- Check a proposal by crossing out one supplied letter for each answer letter. Cross out on the page; no letter tiles or cutting are needed.
Warm-up: a clue selects the word
Rearrange EARTH to name the organ that pumps blood.
Hint 1
The answer starts with H.
Hint 2
Place H first and T last.
Check the answer and reasoning
HEART
EARTH and HEART each contain A, E, H, R and T once. The clue selects HEART; another rearrangement would still need to fit the clue.
Round 1: use both copies
Rearrange RESCUE to mean safe or firmly fastened. Keep both copies of E.
Hint 1
Start with S.
Hint 2
The last two letters are RE.
Check the answer and reasoning
SECURE
Both words contain C, E, E, R, S and U. A six-letter answer with only one E cannot use the inventory correctly.
Round 2: hear the clue
Rearrange SILENT to mean pay attention with your ears.
Hint 1
Start with L.
Hint 2
The answer ends with TEN.
Check the answer and reasoning
LISTEN
SILENT and LISTEN both use E, I, L, N, S and T. They describe different actions even though they share their letters.
Final: three checked answers
Solve all three: (1) BELOW → a joint in your arm. (2) DUSTY → spend time learning a subject. (3) NIGHT → a single object or item. Show a complete letter inventory for each.
Hint 1
The answers begin E, S and T.
Hint 2
They end BOW, UDY and ING.
Check the answer and reasoning
1 ELBOW; 2 STUDY; 3 THING
ELBOW uses B,E,L,O,W; STUDY uses D,S,T,U,Y; THING uses G,H,I,N,T. Each inventory exactly matches its source word.
Offer support
Write the letters in alphabetical order before solving, and allow an adult to explain the clue. If a player offers a different answer fitting both letters and clue, discuss it rather than treating every unlisted word as wrong.
Finish together
Finish by checking all three final answers letter by letter. Ask which tempting answer was rejected by a clue, and which was rejected by its letters.
If you disagree about an answer, return to the stated rules and compare the written steps. Keep the activity cooperative; a hint is part of play, and nobody needs to be eliminated.
