Composition of a MASSI • Real-life Application • Build Essential Understanding • Grade-Aligned Skills • Final Tips

Topic: Equations • Elementary- Select an expression that matches a word problem; match an expression to a representation; and determine if an equation is true. – Application: Gathering materials for an art project • Middle- Write an equation when given a story problem and solve for variable; solve a multiplication equation for variable. – Application: Solve story problems about spending money at the bowling alley • High- Use a variable to represent an unknown number, write expressions with variables, and simplify expressions. – Application: Filling orders at a hardware store

Real-life Activity Middle: Bowling Elementary: Art Activity High School: Hardware Store

Essential Understanding 3 -5 6 -8 HS • Symbol Use • Combining sets to add and decomposing sets to subtract • Symbol Use • Identifying numbers in story problems • Creating sets • Using a variable to represent an unknown

Adapting for Unique Needs in the Equations MASSI

Final Tips • Use real-life materials to make the lessons meaningful and fun • Be sure to identify how student will respond; program responses into their AT • Have everything ready so can teach at a brisk pace • Teach to a stop sign until get progress; then move on; remember skills repeat in next section • You probably will need to move to new MASSI after 3 -4 weeks for student to cover enough standards to do well on the alternate assessment
