As a teacher who's used multiple test prep resources, this Lumos Learning workbook stands out for its perfect blend of print and digital practice. The physical book feels substantial with clear organization, while the online portal adds that crucial computer-based testing experience kids need.

The answer keys are lifesavers - they don't just give correct answers but explain concepts in student-friendly language. I've caught myself learning new teaching approaches from these explanations!

What surprised me most was how engaged my students became with the online tests. The interface mimics the real IAR testing environment so well that my class treated practice sessions like important missions rather than chores.

The only drawback? Some students finished the online portions faster than expected, craving more questions at the same difficulty level. But with both book and digital resources combined, there's enough material for thorough preparation.

Seeing my students walk into the real IAR test with confidence instead of anxiety? That's made this resource worth every penny. Whether you're a teacher or parent, this workbook delivers exactly what fifth graders need to shine on ELA assessments.
