Type in the Input. The Function Machine applies the function and produces the Output. If you choose [Random], you will have to use some brainpower to figure out the hidden function.
Linear Function Machine
Students play a version of Connect Four, gaining the chance to place a piece on the board by answering questions about simplify fractions, converting fractions to decimals and percents, as well as algebra questions involving fractions.
Practice estimation skills by determining the number of objects, the length of a line, or the area of a shape. Choose the problem type, or choose 'Random' to see a mixture of all three types of estimation questions.
Play a "Connect-Four" style game, earning a game piece each time you answer an estimation question correctly. This game asks the players to estimate the answer to addition, multiplication, and percentage questions. Choose difficulty level, question types, and time limit. Estimator Four is one of the Interactivate assessment games.
Here is a similar interactivity that doesn't have the Connect Four interface.
In this interactivity, you can choose 'Counting' where the students have to estimate the number of stars.
More or Less Estimator
Roll or choose a number in Pascal's Triangle and then click on all entries that are multiples of the number, thereby practicing multiplication tables, investigating number patterns, and investigating fractal patterns.
Arithmetic Four is a Connect Four variation where you have to answer an arithmetic question correctly before you can play a chip. You get to choose the category, the operation, the difficulty level and the time limit.
Arithmetic Quiz is similar but without the Connect Four interface.
Use logic (ie your BRAIN) to drop the ball over the correct tools in the correct order.
This is a clever and engaging version of Galton's Quincunx. It shows the underlying theoretical distribution (a normal curve) as well as the results of dropping mice into the quincunx.
Here is a similar activity (not as cute though). Set them both running and compare...
