About Pirate Math Equation Quest
We developed Pirate Math Equation Quest as an extension of the Pirate Math program developed by Lynn Fuchs, Ph.D., and her colleagues at Vanderbilt University. Our iterations of Pirate Math Equation Quest rely upon the core components of Pirate Math.
From 2015 to 2019, we provided third-grade students experiencing mathematics difficulty with an intensive, individualized word-problem intervention called Pirate Math Equation Quest. During Pirate Math Equation Quest, students received explicit instruction on reading, interpreting, setting up, and solving word problems with a focus on schemas. Students also received modeling and practice related to understanding the equal sign and equation solving within the word-problem intervention.
We identified eligible students experiencing mathematics difficulty as those scoring at or below the 13th percentile on a measure of word problems. During 2015-2018, our first three cohorts of students in Pirate Math Equation Quest: Individual Word-Problem Intervention With Total, Difference, and Change Schemas received the word-problem intervention 3 times per week, for 16 weeks, with sessions lasting approximately 30 minutes.
With our final cohort of third-grade students in 2018-2019, we introduced Pirate Math Equation Quest: Small-Group Word-Problem Intervention With Total, Difference, Change, and Equal Groups Schemas as a small-group word-problem intervention in which groups of 3 to 4 students received the word-problem intervention 3 times per week, for 13 weeks, with sessions lasting approximately 30 minutes. Our final cohort of third-grade students also received a small-group intervention focused on understanding word problems in the State of Texas Assessments of Academic Readiness (STAAR). Students in Pirate Math Equation Quest: Small-Group Intervention for Texas Word Problems in the Grade 3 State of Texas Assessments of Academic Readiness (STAAR) received word-problem intervention 3 times per week, for 6 weeks, with sessions lasting approximately 30 minutes.
From 2021-2024, we designed a new iteration of Pirate Math Equation Quest as an individual intervention for use with students at the fourth-grade instructional level. This version of the program was developed to offer support to Tier-2 and Tier-3 students who require supplemental mathematics support with single- and multi-step word-problem solving. The focus of the Pirate Math Equation Quest Multi-Step Word-Problem Intervention With Total, Difference, Change, and Equal Groups Schemas was single-digit and double-digit additive and multiplicative (single- and multi-step) word problems that included four schemas: Total, Difference, Change, and Equal Groups. The intervention used modeling and practice related to understanding the equal sign, equation solving, and the order of operations. Our three cohorts of students in Pirate Math Equation Quest: Multi-Step Word-Problem Intervention With Total, Difference, Change, and Equal Groups Schemas received the word-problem intervention 3 times per week, for 13 weeks, with sessions lasting approximately 30-35 minutes.
Rigorous evaluations of all four iterations of Pirate Math Equation Quest indicated that third- and fourth-grade students experiencing mathematics difficulty demonstrated improved word-problem performance with Pirate Math Equation Quest compared to students who did not participate in the intervention (Powell, Berry, & Barnes, 2019; Powell et. al, 2021).
Are you wondering which of the four interventions is most appropriate for your students? See the table below for a guide.
Intervention Title | Intended Grade Level | Individual or Small Group? | Schemas Included | Single- or Multi-Step Word Problems? | # of Lessons |
---|---|---|---|---|---|
Single-Step Word-Problem Intervention With Total, Difference, Change, and Equal Groups Schemas | Grade 3 | Small Group | Total, Difference, Change, and Equal Groups | Single-step word problems | 39 |
Multi-Step Word-Problem Intervention With Total, Difference, Change, and Equal Groups Schemas | Grade 4 | Individual | Total, Difference, Change, and Equal Groups | Single- and multi-step word problems | 39 |
Single-Step Word-Problem Intervention With Total, Difference, and Change Schemas | Grade 3 | Individual | Total, Difference, and Change | Single-step word problems | 51 |
Word Problems for the Texas STAAR | Grade 3 | Small Group | Total, Difference, Change, and Equal Groups | Single-step word problems | 18 |

Thank you to the third- and fourth-grade teachers and students of Austin Independent School District who graciously participated in this research project. We also thank the many research assistants at The University of Texas at Austin for their time, effort, and dedication to the project. We have included a few team pictures below.
