A high-elevation math lesson where Grade 3 students master ordering 3-digit and 4-digit numbers within 10,000. Through standard ordering lists, visual height challenges, and an interactive cut-and-paste sorting activity, students build strong place-value skills.

Introduces early 3-digit numbers (100-120), visual skip-counting (2s, 5s, 10s) using constellation maps, and ordering cosmic objects to build sequential logic.

Focuses on identifying double-digit numbers (10-99), representing them using ten-frames and printable base-ten icons, and writing numbers in expanded place value charts (tens and ones) with clear physical boundaries.

Covers single-digit subtraction (1-9) with cosmic countdowns, crossing-out stars or rocket fuel cells, embedded touch-points for backwards counting, and structured workspace templates.

Focuses on single-digit addition (1-9) using embedded touch-point numbers, pictorial representations of spaceships and stars, a persistent 1-20 number path, and large guided workspace boxes for physical alignment.

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 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.
