A magical introduction to subtraction within 10 using cross-out strategies with glowing stars, pixie dust, and magical gems.

A lesson focused on solving one-step word problems involving addition and subtraction. Students practice recognizing active language cues, modeling their thinking, and writing equations.

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 targeted 2nd-grade intervention lesson focused on adding 2-digit numbers with regrouping. Students use place value block drawings, color-coded numbers, and T-charts to build conceptual understanding and solid arithmetic habits.

Students apply their measurement skills to the metric system, learning about centimeters and practicing precise measurement starting at the zero mark.

Students learn to measure to the nearest inch using custom visual rulers. The lesson emphasizes locating the true starting zero mark instead of starting at the physical edge of the ruler.

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 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 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 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.
