I added the lessons in this unit to the existing math curriculum. The
fractions lesson was a good review of the previous math unit while
the lessons on area and spatial pattern recognition complement the
unit that I am currently teaching. Some of the websites in this unit
were too difficult for my third grade class. Therefore, those
activities were modified to either shared reading lessons or exploratory
activities followed by oral directions.
Understand math concepts through manipulation of tangram
Create new puzzles using the 7 tangram pieces.
Understand and use math vocabulary connected to the concepts
was integrated using the Internet as a research tool, developing
spatial relationships, and publishing creative tangram designs.
Students were assessed through a combination of teacher observations,
activity sheets, and student-created tangram puzzles on Hyperstudio
Some students may find it difficult to give explicit directions on how
they solved the tangram puzzles.
Support each math lesson with other activities to reinforce
Reorder chart in lesson 2 to help students see the relationships
among different shapes and to build upon by starting with
simpler relationships to more abstract ones.
