STAAR Scores Soar
A recent analysis for Brazosport ISD revealed that their district wide elementary adoption of ST Math has led to significant gains in students scoring Approaches, Meets, and Masters on STAAR. This large-scale study, which included over 5,000 students using ST Math, compared district accountability scores from 2013 (pre-ST Math) to 2019.
TEKS Correlation
ST Math aligns with TEKS to ensure Texas students develop deep, conceptual understanding of math concepts to equip them for the challenges of the 21st century. Below is a small sample of ST Math puzzles that were designed to meet the rigorous demands of the Texas math standards.

Interested in bringing ST Math to your students?
There are several funding options including the Texas Math Innovation Zones* grant.
Grade K Numbers & Operations: K.3.A
Model the action of joining to represent addition and the action of separating to represent subtraction.
These puzzles ask students to model addition and subtraction by joining and separating birds on a telephone line. Students use the manipulative to find the total number of birds.
Grade 2 Numbers & Operations: 2.6.B
Model, create, and describe contextual division situations in which a set of concrete objects is separated into equivalent sets.
In this example the student has determined that if each purple monster eats 2 pears, as shown by the rate in the top left corner, than 8 pears should be separated equally to feed 4 purple monsters.
Grade 4 Numbers & Operations: 4.3.E
Represent and solve addition and subtraction of fractions with equal denominators using objects and pictorial models that build to the number line and properties of operations.
This puzzle asks students to match a collection of fractions represented with a circular model to a single point on the number line. The blue pieces represent positive numbers, the red indicates a negative number.
Grade 7 Expressions & Equations: 7.10.B
Represent solutions for one-variable, two-step equations and inequalities on number lines.
In this example, the student must find the value of variable “a”. This two-step equation, 4 + 3a = 7, is represented on a number line.
