Number and Operations

Broad Expectation*	Topic	Link to Applet and Description	How good for teacher demos (1-3)?	How easy for students (1-3)?	How good for exploration (1-3)?	Available activities
Understand numbers, ways of representing numbers, relationships among numbers, and number systems

Understand meanings of operations and how they relate to one another	Addition	Adding with Base Ten Blocks - Use base ten blocks to represent addition. Use the "selection marquee" (drag a rectangle) to group up blocks. Base Blocks - base ten block introduction.	3	2	3	built in
	Subtraction	Base Blocks Subtraction - model subtraction with base ten blocks.	3	3	2	built in
	Repeated Operations	Number Patterns and Relationships (<100) - Has a 100 chart and a calculator for pressing, for example, 4+4=,=,=,=. Number Patterns and Relationships (100+) - Same as above but goes to 1000.	3	3	3	Questions Questions

Compute fluently and make reasonable estimate

Algebra

Broad Expectation*	Topic	Link to Applet and Description	How good for teacher demos (1-3)?	How easy for students (1-3)?	How good for exploration (1-3)?	Available activities
Understand patterns, relations, and functions

Represent and analyze mathematical situations and structures using algebraic symbols

Use mathematical models to represent and understand quantitative relationships

Analyze change in various contexts

Geometry

Broad Expectation*	Topic	Link to Applet and Description	How good for teacher demos (1-3)?	How easy for students (1-3)?	How good for exploration (1-3)?	Available activities
Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships

Specify locations and describe spatial relationships using coordinate geometry and other representational systems

Apply transformations and use symmetry to analyze mathematical situations	Patterns & Shapes	Pattern Blocks - Same as the physical blocks, just virtual. Nice tool. Another option.	3	3	3

Use visualization, spatial reasoning, and geometric modeling to solve problems

Measurement
