The "Ways to Make 20 With Three-Piece Puzzles in Full Color" learning center features 33 individual puzzle pieces that students have to put together in sets of three to make an addition sentence that equals 20. Each piece features the parts of a dachshund dressed up in different outfits, which makes completing the puzzle more fun, but it also provides students with hints that help them narrow down which pieces go together. For example, one equation features the dachshund dressed up as a bee, while another features him dressed up to play baseball.

Students must put together all the puzzles, but they also have to complete the practice worksheet. It asks students to color in 20 dog bones and match the 6 numbers below to their correct equation, like filling in the number 10 in the equation 10 + ___ = 20.

This learning center helps students work on their math facts up to 20, which can be helpful when it comes to solving more complex math problems in the future. It supports mental math skills and promotes problem-solving and critical thinking skills as they figure out how to arrange all the pieces of the puzzles correctly.
