3rd grade geometry, measurement, data, and financial literacy

Connect math to shapes, measurements, graphs, and everyday decisions with the TEKS-aligned Mathtastico Units 11–15 e-book. This resource also revisits multiplication and division problem solving, giving Texas teachers materials for lessons, intervention, and targeted STAAR math review.

• Grade: 3rd grade
• Scope: Units 11–15 of the Mathtastico multi-unit series
• Format: Digital e-book in English; no printed book is shipped
• Teaching uses: Classroom instruction, small groups, tutoring, and review

What students will practice

• Multiplication and division: Model and solve one- and two-step problems within 100 and describe relationships in number-pair tables.
• Geometry: Classify two- and three-dimensional figures, identify quadrilaterals, and explore their attributes.
• Area and perimeter: Find rectangular area, break composite figures into rectangles, and calculate polygon perimeters and missing side lengths.
• Measurement: Solve time-interval problems and choose appropriate tools and units for liquid volume and weight.
• Data: Read and organize categorical data in frequency tables, dot plots, pictographs, and bar graphs, then solve related problems.
• Financial literacy: Explore income, resource availability and cost, borrowing responsibilities, and reasons to save.

What is included

• Planning support: TEKS-based unit planning, math vocabulary, and guided questions for lesson goals.
• Pre-assessments: Check prerequisite skills before introducing new learning.
• Guided and independent practice: Teach each skill, then give students opportunities to apply it through practice and word problems.
• Daily spiral review and Problem of the Day: Revisit previously taught skills throughout instruction.
• Homework and games: Reinforce lesson concepts through additional practice and activities.
• Checkpoints and assessments: Use writing prompts, problem-solving questions, practice assessments, and unit assessments to monitor understanding.
• STAAR-style questions: Integrate test-preparation practice into instruction and review.
