Enhance your lessons or reinforce key ideas with these interactives. Each is featured in a TeacherLine course with instructions for how it might be adapted to a particular class setting. Learn how you can enroll in a course.

	Floor Tiles This interactive allows users to explore tessellations on quadrilateral figures by dynamically changing the shape of the figure. — From Shaping Up: Teaching Geometry Using Technology
	Frog in a Well This problem and interactive demonstrate how to identify number relations and patterns and alter variables to change patterns. They can be used together or separately. — From Patterns and Relations
	Histograms This animation and interactive can be used together to demonstrate how different interval sizes affect the shape and presentation of various data. — From Data Analysis and Probability/Making Comparisons with Data Analysis
	Isometric Geoboard This interactive allows students to explore and use a virtual geoboard. — From Measurement of Surface Area and Volume
	Make a Rule This interactive demonstrates the relationship between a real-life situation, the values it presents and the mathematical equation that generates those values. — From Linear Functions
	Mixing Orange Juice This problem addresses proportions and highlights the difference between part-to-part and part-to-whole ratios. Within the problem there is a link to an interactive that provides a visual for thinking about ratios. — From Proportional Reasoning
	Number Cruncher In this interactive game, users guess which function the Number Cruncher has selected by suggesting an "in" number and watching as the machine produces an "out" number. — From Developing Algebraic Thinking
	The Race This problem provides a visual and a graphical comparison of actual speed and average speed over an entire race. Within the problem there is a link to an interactive that relates a visual image of a race with its graphical representation. — From Calculating the Mathematics of Motion
	Real-life Data The following three applets use real-life situations to show how changing the values affect a table and graph. Use them separately or download instructions for using them together. Real-life Data, Example 1 Real-life Data, Example 2 Real-life Data, Example 3 — From Linear Functions
	Space Blocks This interactive offers a series of activities to help students understand surface area. — From Measurement of Surface Area and Volume
	Surface Area This interactive allows users to explore the relationship between volume and surface area of a given shape. — From Measurement of Surface Area and Volume
	Tesselate! This interactive allows students to deform a triangle, rectangle or hexagon in order to create a polygon that tiles a plane. — From Shaping Up: Teaching Geometry Using Technology
