During the launch of this unit, students have been having an awesome time exploring, composing (making), and decomposing (breaking apart) shapes. They have discovered that rectangles can be broken – decomposed – into two triangles. They have also uncovered the reality that two squares can be combined (composed) into a rectangle. These are just two of the many discoveries happening in 101!
This investigation has also stirred up some content specific vocabulary (with more to come!) and there have been many in-depth noticings about shapes, their properties and defining characteristics.
Some words that have already come up:
- vertex (vertices)
- angles (corners)
Below is the article that explains part of our unit. Also, we have been using the top of page 3 as a main part of our geometry exploration thus far! (Feel free to cut out the 7 shapes within the rectangle on top.) Students can use these shapes to play, make new shapes/patterns and explore. Feel free to make observations with them, name the shapes they are making and PLAY with them! You might just be amazed at what they come up with.
