A lesson designed to help students master two-step mathematical word problems by identifying the intermediate and final unknowns. Includes a structured student worksheet and an educator answer guide.

A highly engaging geometric investigation lesson where students step into the role of 'Angle Detectives'. Students use physical protractors to measure angles, discover the 180-degree triangle sum theorem, and classify triangles as acute, right, or obtuse.

A middle-school math lesson focused on identifying and isolating extraneous information in multi-step word problems. It teaches students to separate relevant data from distracting context using an intuitive, column-based graphic organizer.

A comprehensive math lesson designed to master multi-step word problems using all four operations. The lesson features a 'Case File' detective theme, equipping students with a visual CUBES-inspired 'Clue Cracker' strategy, color-coded operation indicators, and differentiated investigation worksheets.

A structured math lesson on 4-digit subtraction within 10,000. It utilizes vertical place value grids to guide students through a multi-step progression from no-regrouping to advanced regrouping across zeros.

A comprehensive assessment lesson focusing on computational fluency across the four operations using multi-digit whole numbers. Students are supported by highly structured grid alignment guides, color-coded operation cues, and dedicated workspace areas.

A math practice lesson focused on 2-digit by 2-digit multiplication using the standard algorithm, featuring blueprint-style grid alignment guides to support student accuracy and place value understanding.

A hands-on STEM project where students design a sustainable playground, using geometry (area, perimeter, surface area) and financial math to stay within a budget and environmental constraints.

A printable, double-sided math worksheet and corresponding answer key designed to help students master reading angles using pre-aligned background protractors and measuring angles using physical plastic protractors.

This lesson guides students to discover and calculate the median as a measure of center. It contains a complete turn-by-turn annotated script and a comprehensive answer key for all pages in the unit pack.

An energetic, neon-arcade-themed multiplication flashcard lesson designed to boost recall speed and mastery for facts 0-12. Includes a whole-class slide deck game, a student response worksheet, and a teacher facilitation guide.

A comprehensive, scaffolded unit on adding and subtracting fractions with unlike denominators (5.NF.A.1 & 5.NF.A.2). Students scale the fraction mountain from basic equivalence to complex mixed-number word problems, supported by progress trackers, teacher rubrics, and targeted practice.

A high-engagement 6th-to-7th grade bridge lesson that connects ratio tables and graphing (NY-6.RP.3a) to the constant of proportionality and proportional relationships (NY-7.RP.2). Students act as detectives solving blueprint puzzles using coordinate planes and ratio analysis.

A math lesson focused on building single-digit multiplication and four-digit addition fluency while integrating self-regulation check-ins to foster a growth mindset.

An engaging elementary math lesson focused on adding and subtracting money, lining up decimals, regrouping across zeros, and solving real-world shopping word problems up to $10.00.

A stations-based decimal addition and subtraction activity where students rotate through virtual storefronts to buy school supplies, tech, sports gear, and room decor within a set budget.

Students explore and master the Marley Park Elementary STAR expectations for 5th-grade leaders. Through scenario analysis, modeling, and justifying correct and incorrect behaviors, they prepare to set a positive example for the school.

Students learn to translate word phrases into numerical expressions and interpret expressions without evaluating them, building critical algebraic reasoning skills for subsequent grades.

Students master the order of operations, including parentheses, brackets, and braces. They learn to evaluate numerical expressions systematically, modeling calculations like structural blueprints.

Students transition from concrete partial quotients to standard long division steps, solving problems with up to four-digit dividends and two-digit divisors. Emphasizes interpreting remainders in real-world contexts and debugging calculation steps.

Students connect conceptual area models to standard multi-digit multiplication, developing procedural fluency with the standard algorithm while maintaining strong place value understanding. Includes error analysis and architectural design challenges.
