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 comprehensive math lesson focused on 3-digit addition with regrouping, utilizing visual base-ten block models and place value charts to guide students from conceptual understanding to standard algorithm mastery.

A highly visual, hands-on lesson that introduces double-digit addition with regrouping using base-ten blocks. Students learn to draw ones blocks, group ten of them together to trade for a tens rod, and record the regrouping process in the standard algorithm.

A set of high-structure math worksheets featuring one-step word problems across all four basic operations, designed specifically with distraction-free layouts and large workspaces for third-grade special education students.

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.

A targeted subtraction without regrouping intervention lesson using base-ten block pictorial representations. Designed for RTI small groups to build conceptual understanding by physically crossing out represented tens and ones before moving to abstract vertical subtraction.

A rigorous math worksheet pack themed around solving detective cases. Students solve 10 single- and multi-step word problems involving 2-3 digit numbers across all four operations, using visual operation checkboxes and spacious dedicated workspaces.

A comprehensive lesson containing high-yield, retro-themed multiplication flashcards for rapid mental recall. Features a fold-and-cut design that guarantees perfect double-sided alignment on any printer.

A math lesson focusing on two-digit addition and subtraction with and without regrouping using dedicated place-value work grids to support 3rd-grade special education students.

A review lesson that connects the standard subtraction algorithm with concrete base-ten blocks and expanded form subtraction, helping students understand the 'why' behind regrouping.

Week 4 of the ESY Wildlife Detective curriculum. Focuses on a comprehensive mixed spiral math review (NJSLS operations, place value, and measurement) through a culminating multi-day outdoor expedition challenge.

Week 3 of the ESY Wildlife Detective curriculum. Focuses on the foundations of multiplication (NJSLS 2.OA, 3.OA) through repeated addition, skip-counting animal clusters, and creating grid-based habitat arrays.

Week 2 of the ESY Wildlife Detective curriculum. Focuses on place value, estimation, and measurement (NJSLS 1.MD, 2.MD, 3.MD) by measuring nest diameters, estimating burrow lengths, and understanding animal sizes.

Week 1 of the ESY Wildlife Detective curriculum. Focuses on addition and subtraction mastery within 20 and 100 by tracking animal footprints, counting steps, and analyzing forest trail data. Scaffolded for grades 1-4.

A collection of three clean, distraction-free 3-digit addition worksheets and answer keys, each containing a mixed set of 5 regrouping and 5 non-regrouping vertical calculations formatted for print.

A collection of mixed 3-digit addition and subtraction worksheets and answer keys, featuring mixed operations with and without regrouping. Excellent for cumulative review and operational fluency.
