This resource contains problems from the 13 Readiness Standards for Grade 8 Mathematics in Texas. Since problems from the Readiness Standards make up about 60 – 65% of the STAAR test, this makes an ideal take-home review for the test, or a great resource for intervention before the second and third retakes. The questions are written in the style of the Readiness questions on previous STAAR tests. The TEK is at the top of the page, so students can use it to search for additional problems in the Internet if they feel they need more practice in a particular area. A two page answer key is also included.
8.2 D order a set of real numbers arising from mathematical and real-world contexts.
8.3C use an algebraic representation to explain the effect of a given positive rational scale factor applied to two-dimensional figures on a coordinate plane with the origin as the center of dilation.
8.4 B graph proportional relationships, interpreting the unit rate as the slope of the line that models the relationship.
8.4C use data from a table or graph to determine the rate of change or slope and y-intercept in mathematical and real-world problems.
8.5D use a trend line that approximates the linear relationship between bivariate sets of data to make predictions.
8.5G identify functions using sets of ordered pairs, tables, mappings, and graphs.
8.5I write an equation in the form y = mx + b to model a linear relationship between two quantities using verbal, numerical, tabular, and graphical representations.
8.7A solve problems involving the volume of cylinders, cones, and spheres.
8.7B use previous knowledge of surface area to make connections to the formulas for lateral and total surface area and determine solutions for problems involving rectangular prisms, triangular prisms, and cylinders.
8.7C use the Pythagorean theorem and its converse to solve problems.
8.8C model and solve one-variable equations with variables on both sides of the equal sign that represent mathematical and real-world problems using rational number coefficients and constants.
8.10C explain the effect of translations, reflections over the x- or y-axis, and rotations limited to 90°, 180°, 270°, and 360° as applied to two-dimensional shapes on a coordinate plane using an algebraic representation.
8.12D calculate and compare simple interest and compound interest earnings.
