Cosmic Base Ten

A 4-week intensive math intervention program set in a space exploration universe, designed for multi-grade students with disabilities in Grades 5–8. It covers additive thinking, place value, and decimal regrouping, anchored in Grades 4–6 standards with a Grade 5 core middle ground.

Solar Grid Sync

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.

Solar Charging Station

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.

Cosmic Cargo Regroup

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.

Nebula Navigation

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.

Stellar Fuel Shares

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.

Wormhole Regrouping

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

Galactic Trade Hub

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.
