Bar Models are called "strip diagrams" in the TEKS.
Story Problem Types
First Grade TEK: use objects and pictorial models to solve word problems involving joining, separating, and comparing sets within
20 and unknowns as any one of the terms in the problem such as 2 + 4 = [ ]; 3 + [ ] = 7; and 5 = [ ]  3;
Second Grade TEK: represent and solve addition and subtraction word problems where unknowns may be any one of the terms in the problem.
