Submitting Organization: INSPIRE Research Institute for Pre-College Engineering @ Purdue University
Grade Level: 1st Grade
Subject Area: Math
Standards Alignment: Common Core State Standards – Mathematics
1.G.2 Students use algorithms and tangram set pieces (2-D shapes) to create composite shapes. Note: Computer science standards related to computational thinking are also addressed.
Description of the Activity:
- Review what tangrams are and the movements (rotate (turn), flip, and move (slide)) used to position shapes.
- Review the shape names. Students need to also differentiate the triangles by size.
- Have students follow along as you demonstrate how to follow Algorithms 1 and 2. Have them make observations about the results. Point out that you will focus on algorithms that produce the same results.
- Allow students to try Algorithms 3 and 4 one at a time.
- Have students complete the Develop your Own Algorithm sheet.
- Have students state in their own words what they learned.
- Explain in your own words what we learned today.
