Okay Chris... if you want to do math. Choose something small, these are the TEKS that she is probably talking about.
(2) Number, operation, and quantitative reasoning. The student uses fractions in problem-solving situations. The student is expected to:
(A) generate a fraction equivalent to a given fraction such as 1/2 and 3/6 or 4/12 and 1/3;
(b) generate a mixed number equivalent to a given improper fraction or generate an improper fraction equivalent to a given mixed number;
(C) compare two fractional quantities in problem-solving situations using a variety of methods, including common denominators; and
(D) use models to relate decimals to fractions that name tenths, hundredths, and thousandths.
(10) Measurement. The student applies measurement concepts involving length (including perimeter), area, capacity/volume, and weight/mass to solve problems. The student is expected to:
(A) perform simple conversions within the same measurement system (SI (metric) or customary);
(b) connect models for perimeter, area, and volume with their respective formulas; and

(C) select and use appropriate units and formulas to measure length, perimeter, area, and volume.
My suggestion would be to do 5.10C which is using appropriate units and formulas for perimeter, area and volume - if you are comfortable with that TEK. This is a really easy section to come up with gestures for and it will make a big impact. You might also want to look at some released TAKS test questions - since they are getting ready for TAKS and include those into your lesson.
Good luck - let us know if you have more questions!
