Kids Jigsaw Puzzles with 100 to 150 pieces are generally recommended for ages 5 and up. There are two ways children can build 100 to 150 piece puzzles and this is either by starting with the corners to build a border and then filling in the middle, or by colour categorising the pieces to form areas with them, and then eventually putting them altogether. Whichever they may choose the challenge will help build key skills that form the foundations of reading, writing and Maths skills! Our gorgeous range of 100 piece and 150 piece kids jigsaw puzzles make the perfect birthday gift for five and six year old's.
