The related values can be organized in a table and the ordered pairs graphed on a rectangular coordinate system. Students note that the graph is a straight line and use this to predict other values. Again, starting with an x value of 0 they find the resulting y value of .3. Using this as the new x value gives a value of .33 for y. Use patterns, relationships, and functions to model situations and to solve problems in mathematics and in other subject areas.
Students analyze a given series of terms and fill in the missing terms.
Students develop an awareness of the assumptions they are making. Students compare different pay scales, deciding which is a better deal. They create a table comparing the pay for different numbers of hours worked and decide at what point the hourly rate becomes a better deal. Students supply missing fractions between any two given numbers on a number line. For example, students might label each of five intervals between 59.34 and 59.35.
