### 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 Operations (e.g. +) Pan Balance - Numbers or numeric expressions (e.g., 2+3 or 5-1) can be put on each side of the pan balance. 3 2 3 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 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

 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 measurable attributes of objects and the units, systems, and processes of measurement Apply appropriate techniques, tools, and formulas to determine measurements Time Judy Clock - Interactive clock. Click the circles in the upper left and right to show the time written out and digitally. 3 3 3

### Data Analysis and Probability

 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 Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them Select and use appropriate statistical methods to analyze data Develop and evaluate inferences and predictions that are based on data Understand and apply basic concepts of probability

### Explanation of Column Headings

(This page is organized using the five content areas in school mathematics, as articulated in the NCTM Principles and Standards, 2000.)

• Broad Expectation - from NCTM Principles and Standards (2000) for each of the five NCTM Content Standards
• Topic - Mathematical topic
• Link to Applet and Description - A description of the applet and hyperlink to the page.
• How good for teacher demonstrations (1-3)? - Is this applet good for the teacher to use in a class demonstration?

3=Excellent for class demonstrations of mathematics
2=Fair to Good for class demonstrations of mathematics
1=Not designed for class demonstrations of mathematics

• How easy for students (1-3)? - How easy is the applet for students to use, without instruction?

3 = No advance instruction needed (very easy to use).
2 = Short demonstration helpful (pretty easy to use).
1 = Extensive demonstration needed (hard to use without an explanation).

• How good for exploration (1-3)? - Is this applet designed for student exploration?

3=Excellent for student exploration of mathematics.
2=Fair to Good for student exploration of mathematics.
1=Not designed for student exploration of mathematics.

• Available activities - Are there student activities already written to accompany this applet? If so, links are provided.
