Pilot Edition Texas OER K-5 Math, COVID Emergency Release (CER 2.0)
The COVID Emergency Release Pilot Edition V2 K-5 Math is currently called Eureka Math TEKS Edition and was built based on Texas standards. Students develop conceptual understanding, practice procedural skills and fluency, and apply what they learn in real-world scenarios. All topics are linked across modules and grade levels to help students build an enduring understanding of math through rigorous instruction.
The Texas Education Agency developed these learning resources as one option for school districts during COVID. The use of these resources is optional. Prior to publication, materials went through a rigorous third-party review. Review criteria included TEKS alignment, support for all learners, progress monitoring, implementation supports, and more. These are pilot materials and will not be submitted for IMRA Review. These materials have been revised through our continuous improvement process to form our first non-emergency edition which was submitted to the State Board of Education (SBOE) as part of the Instructional Materials and Review (IMRA) 2024 process. Edition 1 can be accessed at the State Board of Education webpage.
For more information regarding these instructional materials please visit the TEA Available Instructional Materials website. If you have questions or concerns about the instructional materials, please email us at openeducationresources@tea.texas.gov.
Determining Slopes from Equations, Graphs, and Tables
Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.
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.
Writing Geometric Relationships
Given information in a geometric context, students will be able to use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
Solutions of Simultaneous Equations
Given a graph of two simultaneous equations, students will be able to interpret the intersection of the graphs as the solution to the two equations.
Comparing and Explaining Transformations
Given rotations, reflections, translations, and dilations, students will be able to develop algebraic representations for rotations, and generalize and then compare and contrast the properties of congruence transformations and non-congruence transformations.
Mean Absolute Deviation
Given a set of data with no more than 10 data points, students will be able to determine and use the mean absolute deviation to describe the spread of the data.
Generalizing about Populations from Random Samples
Given a population with known characteristics, students will be able to use a variety of methods to generate random samples of the same size in order to understand how a random sample is representative of a population.
Evaluating Solutions for Reasonableness
Given problem situations, the student will determine if the solutions are reasonable.
Predicting, Finding, and Justifying Solutions to Problems
Given application problems, the student will use appropriate tables, graphs, and algebraic equations to find and justify solutions to problems.
