6 Targeting the 2 Percent
This resource provides reading intervention lessons for teachers who work with students in grades K–5. Targeting the 2 Percent (T2%) aims to improve the instruction, content knowledge, and academic achievement of Texas students transitioning from assessments based on modified standards to the general state assessment, the State of Texas Assessments of Academic Readiness (STAAR®).
For more information about this project and other materials available, visit the T2% Support Center.
Quantifying Changes in Chemical Reactions: Empirical Formula
Given the descriptions or chemical formulas, students will use relative masses of elements in substance to calculate and determine the ratio of atoms of each element in a compound so as to determine percent composition or empirical formula.
Stoichiometry
Students will model real-world formulas and chemical reactions to investigate the meaning of limiting reactants.
