Debugging Number Errors

A comprehensive review and assessment of all four fraction operations. Students demonstrate their mastery through an interactive review, final unit assessment, and student reflection.

Multiplying and dividing fractions using area models, understanding scaling, and dividing unit fractions by whole numbers. Visual models help conceptualize these concepts.

Adding and subtracting fractions with unlike denominators, including mixed numbers and standard real-world word problems. Students learn to find equivalent fractions with common denominators to add and subtract.

Mastering equivalent fractions and simplifying. Students discover visual equivalencies, identify common denominators, and reduce fractions to their simplest form using step-by-step mathematical reasoning.

An exciting path-based board game where 4th graders practice dividing five-digit numbers by single-digit divisors. Students roll a 10-sided die to determine divisors or navigation, solve division problems, and accumulate remainders as bonus points to win the game.

A Grade 4 math lesson introducing multiplication of a whole number by a unit fraction using visual models including repeated addition, fraction strips, and number lines.

A highly structured, scaffolded lesson designed to help students master three-digit by three-digit multiplication using color-coded grids, a step-by-step task-analysis checklist, and sequential progress monitoring.

A single-digit multiplication lesson centered around animal counts and habitat scenarios. Students solve word problems using visual representations like arrays, equal groups, and tape diagrams.

A complete outdoor learning experience where students explore mathematical concepts in the natural world. This lesson bundle connects geometry, measurement, estimation, and word problems directly to physical nature finds, followed by an indoor data-analysis session.

A math lesson focused on solving and interpreting 4-digit by 1-digit division word problems with remainders in a mountain climbing theme. Includes task cards, a recording sheet, and a detailed teacher answer guide.

A sweet, bakery-themed math lesson where students analyze five-digit division problems to identify, explain, and correct common calculation mistakes.

A Grade 4 math lesson built on Building Thinking Classrooms (BTC) principles and thin-slicing. Students use highly progressive tasks at vertical surfaces to discover, identify, and draw lines of symmetry in geometric figures.

Week 4 is the capstone week where students synthesize their additive and subtractive decimal skills in the context of money. They solve multi-step commercial transactions, balance credit records, and purchase starship upgrades.

Week 3 focuses on partitioning, equivalent fractions, and adding or subtracting fractions with like and unlike denominators. Students practice fair-sharing reactor cores, dividing cargo weight, and mapping stellar orbits using fraction bars.

Week 2 focuses on mastering whole-number regrouping and multi-column carrying in the context of starship cargo inventories. Students use base-10 blocks to bundle ones into tens and tens into hundreds, bridging visual modeling directly to standard vertical algorithms.

Week 4 focuses on standard algorithm decimal addition and subtraction, multi-step problem consolidation, and direct assessment of skills to confirm crew flight readiness.

Week 3 focuses on multi-step additive reasoning, decimal subtraction, and aligning coordinates using star charts and compass tools to plan flight vectors for the fleet.

Week 2 focuses on decimal addition and subtraction with and without regrouping, using visual decimal grids and standard plastic base-10 blocks to represent tenths and hundredths in solar charging grid scenarios.

Week 1 focuses on deepening place value understanding and multi-step addition of decimals and whole numbers in space grid systems. Students practice regrouping tenths and wholes, balancing battery loads, and tracking fuel payload readings.

A standard division lesson where students solve 3-digit by 1-digit problems to decode a funny prehistoric riddle. Includes grid-aligned layout sheets for the standard algorithm.
