Unlock Math

Strong use of worked examples through video instruction where the teacher demonstrates problems step-by-step. Complete solutions are provided after practice exercises.

Video lessons show teacher 'demonstrating with numerous examples' and 'complete solutions are presented after each question in the exercises'

Provides extensive parent support including gradebook guides, QuickStart guides, and live chat with licensed teachers. Strong customer service support for implementation.

Includes 'QuickStart Guide' and 'Gradebook Guide'; 'live chat support with licensed teachers' during homeschool hours; praised customer service

Follows a clear direct instruction model with structured video lessons, guided practice, and independent work. Teacher-led instruction is the primary delivery method.

Consistent lesson format with video instruction, practice problems, and assessments; described as having 'clear explanations' and 'easy-to-follow' structure

Incorporates retrieval practice through daily warm-ups reviewing previous material and Stay Sharp problems for cumulative review. Multiple assessment opportunities available.

Warm-ups include 'five problems based on previously learned material' and Stay Sharp problems provide 'continuous review'; tests can be 'retaken multiple times'

Uses a mastery-based approach with units that must be completed sequentially and minimum grade thresholds before advancing. Includes systematic review through warm-ups and 'Stay Sharp' problems.

Parents can set minimum grade thresholds before students advance, warm-ups review previous material, and Stay Sharp problems provide continuous review

The curriculum appears to emphasize procedural instruction through video demonstrations and practice problems. Limited evidence suggests conceptual development beyond step-by-step problem solving.

Reviews mention 'one problem at a time teaching' and 'step-by-step solutions' but don't describe conceptual exploration or multiple solution methods

Comprehensive progress tracking and reporting but lacks placement tests for initial skill assessment. Parents can view detailed student performance and problem-specific progress.

Extensive gradebook showing 'where students might need additional practice' but 'lack of placement/diagnostic tests' noted as drawback

Uses animated digital screens rather than whiteboards for instruction and includes sophisticated drawing tools for graphing activities. Limited evidence of varied visual models for conceptual understanding.

Teacher uses 'animated screen rather than a whiteboard' and students can 'sketch answers with drawing tools' for graphing coordinate planes

Includes Challenge questions for critical thinking but limited evidence of systematic word problem instruction or real-world application strategies.

Optional Challenge questions 'stretch students' critical thinking skills' but no mention of systematic word problem schemas or strategies
