Explain to students that they will the Patch Tool to model part-whole relationships. The directions for using the
tool should be reviewed prior to this lesson. The students may need to
be guided in how to drag the pattern blocks to the work area. When
making comparisons, the students can drag one pattern block on top of
another one to compare the area of the region. If your technological
resources are limited, you can also create and print pattern block
activity sheets using the Dynamic Paper Tool. Pattern blocks can be found under the Shapes tab.
Have students work in pairs using the Web-based pattern blocks
to explore relationships among the four shapes. Use the same Guiding
Questions found in Lesson One. This will facilitate exploration with a
new tool, help the students focus on the mathematical concepts
demonstrated with this region model, and reinforce the content of the
previous lesson, Investigating with Pattern Blocks.
The students should use the virtual pattern blocks to answer the questions. Provide students with a new, blank copy of the Region Relationships 1 Activity Sheet and ask them to complete it.
Region Relationships 1 Activity Sheet
Encourage students to discuss various options with their
partner. This allows students to articulate their understandings,
making them available for discussion, clarification, and extension.
