Decimal Addition Puzzle - Tenths
Students must rearrange 16 puzzle pieces so that the addition problems match the solution on each side.
I have included two different sizes of the same puzzle. The smaller size fits onto one page of a4 and the large puzzle requires 6 pieces of paper. The larger puzzle would be idea for group work. For each puzzle I have included shaded and non-shaded puzzle pieces. (The shading helped my students identify the puzzle pieces easier to cut out and work with).

Tips to use these puzzles
1. To increase the lifespan of these puzzles consider laminating and numbering the puzzles to make them easier to sort out if they get mixed together.
2. The puzzle pieces are mixed so students can cut them out before they start answering them – saves lots of cutting time!
3. If working in pair or groups have each student take it in turns to match a card and justify their answer to the group. Alternatively split the cards between the group members and place one in the middle of the table. Pupils work out the questions on that card together then check their own cards to see who has the matching one.
4. Whilst monitoring pupils work have the answer key in your hand to spot any early mistakes and encourage students to check their work.
5. Have pupils identify which three questions they found the most difficult and explain why.
You may wish to extend this further and have pupils create their own puzzles. They can hand write their own questions and then cut it out and mix them up for their peers to try.
