Students practice multi-digit subtraction using the standard algorithm, with a focus on decomposing/unbundling. Focus on ALN HLC 4 and 4.NBT.B.4.
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.
