Shark Subtract

A foundational lesson introducing early elementary students to calendar concepts, including days of the week, weekdays versus weekends, and the twelve months of the year, contextualized with real-world school, home, and seasonal scenarios.

A fun, puzzle-packed math lesson where students become Grid Detectives, using place value clues (tens and ones, plus-one, minus-one) to solve 100-chart mystery pictures and unlock hidden pixel art drawings.

An introductory lesson to multiplication using equal groups and visual representations. Students learn to connect repeated addition to multiplication using starry-themed groups.

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.

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 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.

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.
