Primary/Junior Mathematics Part 1 – Discussion Post #8
Select one manipulative and describe how it could enhance the understanding of a mathematical concept or big idea. Align the tool to a grade and suggest a hands-on task.
Tangram is a puzzle made from 7 differently-sized shapes that, when placed in a specific order, create an image. Tangrams are a great way to reinforce themes within geometry, such as shapes, sides, angles, and vertices. Additionally, through the continued use of tangrams, students are encouraged to recognize shapes and mathematical themes in their everyday life. The different sizes, shapes, and colours add to the sensory stimulation that engages students and keeps them attended to the activity at hand.
I have seen great success in using tangrams in grades as early as kindergarten. Students can be prompted to create an object using tangrams, contributing to their spatial awareness, creativity, and problem solving. Students can also be provided with silhouettes in which they must make their tangram pieces fit. This type of activity has now be enhanced through the use of the Osmo tangram application. The Osmo uses an iPad, tangram shapes, and a mirrored lens over the iPad’s camera to create a digital game that has students align their shapes on the table into the shape displayed on the iPad. The application then takes them through levels and different tangram puzzles using the same shapes. Here’s some more information about this engaging task:
