Software/interactive sites
Investigating the Concepts of Triangle and Properties of Polygons This two-part example describes activities using interactive geoboards to help students identify simple geometric shapes, describe their properties, and
develop spatial sense. 
Creating, Describing and Analyzing Patterns This interactive site illustrates  how students can create pattern units of squares, then predict how patterns with different numbers of squares will appear when repeated in a grid, and check their predictions
Learning Geometry and Measurement Concepts The three-part ladybug example presents a computer environment in which students can use their knowledge of number, measurement, and geometry to solve interesting problems. 
Tanagram Puzzles In this activity children describe figures and visualizing what they look like when they are transformed through rotations or flips or are put together or taken apart in different ways. 
Number Relationships In this two-part example virtual hundred boards and calculators furnish a visual way of highlighting and displaying various patterns and relationships among numbers.
Estimation Strategies In this multipart video example, the decisions the teacher makes and the class discussions contribute to students' opportunities to connect their understandings
of number, measurement, geometry, and data in order to make estimates.
