This activity allows the user to enter a set of data, plot the data on a coordinate grid, and determine the equation for a line of best fit.  

GeometricSolids 

Geometric Solids

This tool allows you to learn about various geometric solids and their properties. You can manipulate and color each shape to explore the number of faces, edges, and vertices, and you can also use this tool to investigate the following question: For any polyhedron, what is the relationship between the number of faces, vertices, and edges? What other questions can this tool help you answer? 

FactorGame

PanBalanceNumbers 

Pan Balance – Numbers

Use this tool to strengthen understanding and computation of numerical expressions and equality. In understanding equality, on eof the first things students must realize is that equality is a relationship, not an operation. Many students view "=" as "find the answer." For these students, it is difficult to understand equations such as 11=4+7 or 3×5=17–2. 
PanBalanceShapes 

Pan Balance – Shapes

Build up to algebraic thinking by exploring this balance tool using shapes of unknown weight. Challenge yourself to find the weight of each shape in one of six built-in sets or a random set.  
PanBalanceExpressions 

Pan Balance – Expressions

This interactive pan balance allows numeric or algebraic expressions to be entered and compared. You can "weigh" the expressions you want to compare by entering them on either side of the balance. Using this interactive tool, you can practice arithmetic and algebraic skills, and investigate the important concept of equivalence. 

FiveFrame
