Students practice converting between fractions and decimals in two of these puzzles and and practice converting between fractions and percents in the other two puzzles. Puzzles have 2 levels for differentiation in the classroom and answer keys are included for all as well as a recording sheet for students to show their work. In the simpler level, the outside edges are blank, so if students are having difficulty, have them arrange the pieces so the blank sides are on the outside and the letters are all facing in the same direction. In the more challenging level, the edges have additional problems/answers in the border to make solving a little more difficult. Set includes 4 different puzzles with 2 different levels of difficulty for students to practice with fractions, decimals and percents. This is a great activity for students to self-check their understanding and giving them the opportunity to work together. You can use the puzzles on different days, at stations or give the struggling students the simpler variation.
