My Take
This app challenges students to fit tangram pieces into a a puzzle. It starts out fairly easy to allow them to learn how to use the app but quickly the puzzles become challenging.
Students are motivated to find solutions to the puzzles and it is easy to move the pieces in and out of the puzzle to find the appropriate solution. Students do not turn or flip any of the pieces but drag them directly into the puzzle.There are multiple ways to solve some of the puzzles others only have one solution. Students are able to choose a background that does not change the puzzle.
You can also earn hints to use with the harder puzzles.
This is a great for working with kids on spatial awareness and harder geometry concepts. It also teaches patience and perseverance as students often need to try multiple solutions until they find one that works.
How I Use It
I use it as an extension activity during math time. I found it to be challenging for many of my student but it provided sufficient challenge for my higher level students in 3rd grade. Students will typically work independently but will often collaborate on the harder puzzles to come up with solutions.
