ESTAR II Intervention Modules
ESTAR II intervention modules are designed for students in grades 3 and 4. A total of eight modules containing lessons, student books, and teacher masters are available for download.
Kinetic Molecular Theory
This resources allows students to explore the postulates of the Kinetic Molecular Theory in order to better understand why gas particles behave the way that they do.
High School Algebra I Intervention Modules
These intervention modules are designed to supplement core instruction and develop the conceptual understanding and procedural knowledge of algebra-readiness skills.
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.
Defining Similarity
Given similar figures, the student will use critical attributes to define similarity.
Generalizing Proportions from Similar Figures
Given a pair of similar figures, including dilations, students will be able to generalize that the lengths of corresponding sides are proportional.
Graphing Proportional Relationships
Given a proportional relationship, students will be able to graph a set of data from the relationship and interpret the unit rate as the slope of the line.
Analyzing Scatterplots
Given a set of data, the student will be able to generate a scatterplot, determine whether the data are linear or non-linear, describe an association between the two variables, and use a trend line to make predictions for data with a linear association.
