Prior Standard of Learning

8.18             The student will solve multistep linear inequalities in one variable with the variable on one or both sides of the inequality symbol, including practical problems, and graph the solution on a number line. 

Post Standard of Learning

AFDA.5       The student will determine optimal values in problem situations by identifying constraints and using linear programming techniques. 

 

The student will investigate the passage of time and

a) tell time to the hour and half-hour, using analog and digital clocks; and

b) read and interpret a calendar.
